1. Safety instructions


Only gerotor pump units of series 143

tested and

approved by SKF in accordance with ATEX

Directive 2014/34/EU are permitted to be

used in potentially explosive atmospheres.

The relevant class of explosion protection is

indicated on the gerotor pump unit’s rating

plate.

1.1 Special safety instructions regarding

explosion protection

○ Always behave so as to avoid explosion hazards.

○ A written work authorization from the operator is required prior to initiating work in potentially explosive atmo-spheres. Unauthorized persons must be kept away.

○ There must be no evidence that parts of the explosion protection are missing or non-functional. If this is not excluded, switch off the machine/gerotor pump unit and immediately notify the supervisor.

○ Explosion protection measures must never be deactivated, changed, or bypassed.

○ The introduction of ignition sources such as sparks, open flames, and hot surfaces into potentially explosive atmospheres is prohibited.

○ Inspect the product at regular intervals for damage that may present a risk of ignition.

○ The lubricant’s ignition temperature has to be at least 50 kelvin above the maxi-mum permissible surface temperature.

○ Use only tools and clothing approved for use in potentially explosive atmospheres (ESD).

○ Transport/assembly/repairs and work on electrical components may be performed only if it is ensured that there is no ex-plosive atmosphere present.

○ Repairs or modifications to explosion-proof machinery may be performed only by the manufacturer or a workshop rec-ognized by a notified body and accepted by the manufacturer. If the work is not performed by the manufacturer itself, the repair must be accepted and approved in writing by a recognized expert. The repair is marked by a repair sign on the machine containing the following infor-mation: - Date - Executing company - Type of repair - If applicable, mark by expert

○ Shipping damage may lead to the loss of explosion protection. If there is apparent shipping damage, do not install/put into operation the product.

○ All parts of the grounding concept must be properly present and connected with the main machine.

○ If lifting eyes are removed after installa-tion, seal the threaded holes according to the protection class.

○ Handle components of the product in such a way that no sparks may arise from tilting, dropping, slipping, rubbing, or striking. If necessary, cover compo-nents by appropriate means.

○ Fill level monitoring with min. pre-warn-ing and max. must be provided or appro-priate organizational measures taken to monitor the temperature of the bearings.

○ Prevent/immediately remove accu-mulated dust. Accumulated dust has a thermal insulating effect and promotes the formation of a potentially explosive atmosphere when agitated/swirled.

○ The product must be integrated into the operator’s lightning protection scheme.

○ All parts must be inspected for corro-sion on a regular basis. Replace affected parts.

○ Terminal boxes must be securely closed and the cable glands properly sealed.

○ Any additional electrical monitoring equipment must be securely connected and correctly configured.

○ The motor bearings must be replaced once they reach their nominal service life or they must be inspected to verify suit-ability for further use. (see Chapter 9 as well as operating instructions from the motor manufacturer).

o Electrical circuits such as electrical fill

level monitors must be established by an

intrinsically safe circuit, e.g., through the

installation of an ATEX-compliant isolat-

ing switch by the customer.

o Any components connected or flanged

to the ATEX gerotor pump unit must be

ATEX-compliant.

o The motor connection of the gerotor

pump unit is connected in accordance

with the enclosed instructions from the

ATEX motor manufacturer. These instruc-

tions are stored in the motor’s terminal

box.

o The customer must install adequate

overload protection (motor circuit break-

er) for the power consumption of the

gerotor pump motor.

o When installing the gerotor pump unit,

make sure that the setup location is flat

and low-vibration.

o To limit the maximum system pressure,

the customer must install a pressure

regulating valve immediately after the an-

nular gear.

o Only lines that are made of corrosion-

resistant material may be used. These

must also be grounded.

o The user must make sure through the

choice of the lubricant to be delivered

that no reactions capable of serving as an

ignition source will occur in conjunction

with the potentially explosive atmosphere

expected.

2. Lubricants

2. Lubricants

2.1 General information

Lubricants are used specially for specific

applications. To fulfill the task, lubricants

must meet various requirements to varying

degrees. The most important requirements

for lubricants are: ○ Reduction in friction and wear

○ Corrosion protection

○ Noise reduction

○ Protection against contamination/ingress of foreign matter

○ Cooling (primarily for oils)

○ Durability (physical/chemical stability)

○ Compatible with as many materials as possible

○ Economic and environmental aspects

2.2 Selection of lubricants

SKF Lubrication Systems considers lubri-

cants to be an element of system design.

The selection of a suitable lubricant should

reasonably be made during the design of

the machine and forms the basis for plan-

ning the centralized lubrication system.

The manufacturer/operator of the machine

should preferably make the selection with

the supplier of the lubricant on the basis of

the requirements profile of the specific task.

If you have no or little experience selecting

lubricants for centralized lubrication sys-

tems, please contact SKF.

We gladly assist our customers in the selec-

tion of suitable components for feeding the

selected lubricant and in the planning and

design of a centralized lubrication system.

This may spare you potentially costly

downtime due to damage to the machine/

system and/or damage to the centralized

lubrication system.

Only lubricants specified for the

product may be used (see “Tech-

nical data” chapter). Unsuitable

lubricants lead to failure of the

product and possibly to property

damage.

Do not mix lubricants. This can

have unpredictable effects on the

usability and this function of the

centralized lubrication system.

Due to the large number of pos-

sible additives, it is possible that

individual lubricants that meet

the required specifications ac-

cording to the manufacturer’s

data sheet are not suitable for

use in centralized lubrication sys-

tems (e.g., incompatibility

between synthetic lubricants and

materials). To avoid this, always

use lubricants tested by SKF.

2.3 Material compatibility

The lubricants must be compatible with

the following materials: ○ Steel, gray cast iron, brass, copper,

aluminum

○ FKM (FPM), ABS, PA, PU

2.4 Aging of lubricants

In case of extended machine downtime,

check before re-commissioning that the

lubricant is still suitable for use in terms of

chemical/physical signs of aging. We recom-

mend performing this inspection after 1

week

of machine downtime.

In case of doubt regarding the suitability of

the lubricant, replace it before re-commis-

sioning and, if necessary, perform an initial

lubrication manually.

It is possible for lubricants to be tested in the

company's laboratory for their suitability for

pumping in centralized lubrication systems

(e.g., "bleeding").

Please contact SKF if you have further ques-

tions regarding lubricants.

An overview of the lubricants we have

tested is available on request.

2.5 Lubricants in potentially explosive

atmospheres

The lubricant’s ignition tempera-

ture has to be at least 50 kelvin

above the maximum permissible

surface temperature.

3.4 Functional description of gerotor

pump units

)See Figure 3

SKF gerotor pump units of product series 143 are used in circu-

lating-oil and total-loss lubrication systems in a flow rate range of

0.85 to 50 l/min.

The standard permissible ambient temperature is between 0 and

+40°C. Higher ambient temperatures are possible, though they lead

to a reduction in motor performance and thus the delivery rate. In

this case, the maximum permissible temperature of the pumped

medium must be reduced.

The permissible temperature of the pumped medium is between 0

and +60°C.

The gerotor pumps include a gasket set made of FKM (FPM).

SKF gerotor pump units feed lubricating and hydraulic oils from a

reservoir and into the pipe system of a centralized lubrication sys-

tem. In doing so, they increase the energy of the pumped medium

(pressure increase) to overcome flow resistance in the pipelines

(pressure loss), the components (filters, valves, distributors), and the

bearings and friction points.

SKF gerotor pump units of different types and performance ratings

are used depending on the type and size of the centralized lubrica-

tion system and the lubricant (see pump code or “Technical data”

chapter).

3.5 Operation of the gerotor pump units

)See Figure 4

SKF gerotor pump units of product series 143 have a constant dis-

placement volume and one delivery circuit.

The annular-toothed feeding element, also referred to as the gero-

tor, is equipped with a cycloid contour, which creates a large

tooth meshing length. This yields a low volumetric flow pulsation

and thus very smooth running, low noise production, and good suc-

tion characteristics.

SKF gerotor pumps consist primarily of pump housing (1), the shaft

(2), the displacement elements toothed rotor (3) and annular gear

(4), and the lid (5).

They are driven by attached AC motors of frame sizes 71 to 132 with

flameproof enclosures.

The motors are designed for a rated motor voltage of 230/400 V or

400/690 V for 50 Hz networks with mains voltage fluctuations of

up to ± 10% and frequency fluctuations from -5% to +3% accord-

ing to EN ISO 60034-1.

The normal coils used for this purpose in motors are tailor-

made and meet the IE3 efficiency level according to EU Directive

2009/125/EC.

Special voltage versions with special coils for 50 Hz and 60 Hz net-

works are available for order.

Suction and displacement process

See Figure 4

The shaft drives the centrally mounted toothed rotor in the indicated

direction of rotation via a feather key. The toothed rotor meshes

with the outer, eccentrically mounted annular gear and rotates with

it. The openings between teeth arising in the suction area (S) draw

the pumped medium in. The suction and pressure area is separated

from the tooth meshing area (Z) by a radial gap (R) formed by the

tooth profiles of the annular gear and the toothed rotor as they slide

onto one another. In the pressurized area (P), the fluid is fed to the

pressure port through increasingly small chambers.

Delivery rates and characteristic curves

The indicated nominal delivery rates refer to the nominal output

multiplied by the speed 1400 or 2800 rpm. The actual delivery

rate changes with operating viscosity and back pressure and can be

found in the following characteristic curve diagrams. These diagrams

are based on viscosity data in the range between 20 and 1000

mm2/s in increments of 20, 140, 750, and 1000 mm2/s.

Each gerotor pump has a characteristic curve represented as a func-

tion of the delivery rate above the delivery pressure (back pressure).

It is important to note that temperature influences can render lubri-

cating and hydraulic oils extremely thin or viscous.

Please consult with SKF in advance if you will use lubricating and hy-

draulic oils with an operating viscosity outside the specified range.

See Chapters 4.7.1 to 4.7.2

The curves shown in both figures are based on a viscosity index (VI)

of VI ~ 95, approximately corresponding to standard mineral oil. The

viscosity index describes the slope of the curve and thus the viscosi-

ty-temperature relationship at temperatures other than +40°C.

The lines appear straight because a logarithmic scale was selected

for the ordinate so that the slope of the curves can be determined

easily based on 2 measuring points.

Temperatur °C

The change in the viscosity of oils is disproportionately greater in

lower temperature ranges than in higher temperature ranges. For

example, an oil with a rated viscosity of 100 undergoes the following

viscosity change in different temperature ranges at the same tem-

perature difference:

at +80°C = 18 mm2/s

at +10°C = 875 mm2/s

versus:

at +75°C = 21 mm2/s change of 3 mm2/s

at + 5°C = 1450 mm2/s change of 575 mm2/s.

Foot design IM B34


IMPORTANT NOTE

The information listed in Chapter 5.5 “Transporting the gerotor

pump unit” also applies without restriction to the assembly of the

gerotor pump unit.

6. Assembly

6.1.3 Attachment

The product should, to the extent possible, be protected from hu-

midity and vibration, and should be mounted so that it is easily

accessible, allowing all further installation work to be done without

difficulty.

During assembly and especially when drilling assembly holes on the

system, always pay attention to the following:

○ Check the gerotor pump unit for any shipping damages and for completeness.

○ The IP safety class must be observed.

○ The gerotor pump unit and its ground connection must be con-nected to the equipotential bonding of the main machine.

○ Other units must not be damaged by assembly work.

○ The product must not be installed within range of moving parts.

○ The product must be installed at a sufficiently large distance from sources of heat or cold.

○ Maintain safety clearances and comply with statutory regulations for assembly and accident prevention.

○ Drill the assembly holes for the gerotor pump unit as specified in

this chapter.

○ The various designs of gerotor pump unit are secured using 4 screws according to the specific installation conditions at the location.

○ See the connection diagrams below for the measurements and port dimensions.

○ No radial or axial active forces may occur at the gerotor pump unit.

○ The gerotor pump unit must be installed in a stress-free position.

○ The pump may only be commissioned and operated with an oil supply; the pump must not run dry.

WARNING

Explosion hazard

The lubricant’s ignition temperature has to be at least

50 kelvin above the maximum permissible surface

temperature.

WARNING

Explosion hazard from non-ATEX-compliant attach-

ments and monitoring equipment

Only ATEX-compliant screw unions, lines, attachments,

and monitoring equipment may be installed on the ATEX

gerotor pump units.

- 27 -

EN

6. Assembly

WARNING

Explosion hazard at excessively high temperature

increase

A volumetric flow meter must be used if the viscosity is

<30 mm2/s and the pressure (P) is greater than 30 bar.

If the pump unit is used in systems lacking open delivery lines,

pressure-regulating valves must be provided to limit the maximum

system pressure. The selected cross-section of the intake tube must

be equal to or greater than the cross-section of the suction port

on the gerotor pump unit. SKF recommends the use of filters for

trouble-free operation of the pump unit. Effective filtration prevents

malfunctions while also increasing the service life of the gerotor

pump unit.

A pumped medium of at least the purity class 20/17/14 according to

ISO 4406(c) is recommended. This corresponds to the U.S. standard

NAS code (1638) class 8 and SAE AS 4059 class 8.

A filter rating of approx. 5 to 10 µm meets this requirement.

The filter rating used is always based on the most sensitive compo-

nent in the entire system. This is not necessarily the pump.

The following applies in general:

o Prior to beginning installation, inspect the full scope of delivery for

the gerotor pump unit for any damage or corrosion.

o A fill level indicator with pre-warning min./max. must be installed

on the customer’s system.

o The maximum permissible operating temperature (lubricant

temperature) must not be exceeded. Install a heat exchanger if

necessary.

o Carefully clean screw unions and tubing prior to beginning

installation.

o Lubricant exiting from the return line must not be immediately

resuctioned under any circumstances.

o The intake and return lines in the lubricant reservoir must be

below the minimum lubricant level in all operating states. This

prevents air and foam from being suctioned.

o It must be ensured that screw unions, connections, and connec-

tion elements are leak-free.

o SKF recommends the installation of return line or pressure filters.

However, suction filters should only be used in conjunction with

electric negative pressure switches or contamination indicators.

o Different lubricants must not be mixed together.

o Connect the gerotor pump unit as indicated by the rotation arrow;

see page 15, Fig. 1.

o The gerotor pump unit may only be commissioned and operated

with an oil supply; the gerotor pump must not run dry.

o Ensure cleanliness; components must be installed without

contamination.

o Do not use any cleaning wipes containing lint.

o Existing supply lines must not be damaged by assembly work.

o Other units must not be damaged by assembly work. ○ The gerotor pump unit must be set up at a location with the

specified ambient temperature (see “Technical data”) and max. 1000 m above sea level. Different ambient temperatures and altitudes must be specified on the motor’s rating plate. The motor must not be exposed to direct sunlight at ambient temperatures above 30°C.

○ Air inlets and outlets on the motor fan cowl must not be ob-structed, as this could cause the temperature to rise above the approved temperature class and reduce the service life of the winding insulation.

○ Air inlets and outlets on the motor fan cowl must be checked for cleanliness in a regular inspection.

○ Assess vibrations of the machinery in accordance with ISO 10816-3. However, the maximum permitted vibration velocity is 3.5 mm/s due to the pressure-resistant design of the motors.

○ Drill assembly holes in such a way that no lines, units, or moving parts are damaged or their function impaired. Maintain safety clearances and comply with regulations for assembly and accident prevention.

WARNING

Excessive switching voltage hazard

An isolating amplifier must be inserted if an electrical ATEX

fill level indicator will be used in a potentially explosive at-

mosphere. The maximum permissible voltage Ui must not

be exceeded.

WARNING

Explosion hazard

In case the gerotor pump fails, there must be no risk of

explosion from the gerotor pump unit, the machine, or the

system. The customer must therefore provide a monitor-

ing function, for example in the form of a volumetric flow

meter.

6.3 Setup and attachment

)See Figure 14

The product should be protected from humidity and vibration, and

should be mounted so that it is easily accessible, allowing all further

installation work to be done without difficulty.

Ensure that there is sufficient air circulation to prevent excessive

heating.

For the maximum permissible ambient temperature, see the Chap-

ter 4, “Technical data.”

The mounting position of the product is as shown in the assembly

drawing.

Gerotor pump units in design IM B34 (foot design) are installed

horizontally.

Gerotor pump units in design IM B14 (flange design) can be in-

stalled both horizontally and vertically.

Depending on the model, they can be mounted separately from the

lubricant reservoir or flanged to a lubricant reservoir.

When set up separately, the suction port of the pump may be con-

nected to a lubricant reservoir that is situated higher

(max. 2000 mm).

To flange the gerotor pump unit to a lubricant reservoir horizontally

below the oil level, use a sealed pump in a special design. Consult

SKF's Service department.

Installation examples, Fig. 14

6.2 Minimum mounting dimensions

To ensure enough space for maintenance work and for any disas-

sembly of the product, ensure that the minimum mounting dimen-

sions (Figs. 15 and 16) are maintained.

IMPORTANT NOTE

Observe the technical data (Chapter 4).

CAUTION

Slipping hazard

Centralized lubrication systems must always be free of

leaks. Leaking lubricant is hazardous due to the risk of

slipping and injury.

Beware of any lubricant leaking out during assembly, op-

eration, maintenance, or repair of centralized lubrication

systems. Leaks must be sealed off without delay.

6. Assembly

Be sure to connect the motor so as to guarantee a continuously safe

electrical connection (no protruding wire ends); use the assigned ca-

ble end fittings (e.g., cable lugs, wire end ferrules). Select connecting

cables conforming to DIN VDE 0100, taking into account the rated

current and the conditions of the specific system (e.g., ambient tem-

perature, type of routing, etc. in accordance with DIN VDE 0298-4).

Details regarding electrical connection of the motor to the power

supply, especially terminal and connector pin assignment, can be

taken from the terminal diagram in the terminal box.

WARNING

Electric shock / damage to pump motor

The available mains voltage (supply voltage) must match

the speciications on the rating plate of the motor or of the

electrical components.

It may connected only via a safe galvanic isolation (PELV).

Check the fuse protection of the electrical circuit.

Use only fuses with the prescribed current intensity,

Monitoring equipment that has been triggered (e.g., mo-

tor circuit breaker/fuse) must not automatically switch on

again.

6.7 Electrical motor connection

Consult the motor rating plate for the electrical characteristics of the

motor, such as rated voltage, rated frequency, and rated current.

Observe the guidelines in EN/ISO 60034 (VDE 0530-1) for operation

at the limits of the B ranges (combination of ±10% voltage deviation

and +3/-5% frequency deviation).

This applies especially with regard to heating and deviations in op-

erating parameters from the ratings on the motor rating plate. The

limits must never be exceeded.

IMPORTANT NOTE

Refer to the enclosed operating instructions from the motor manu-

facturer to connect the ATEX motor of the gerotor pump unit. The

information contained therein must be observed.

WARNING

Electric shock

Electrical connections for the product may only be estab-

lished by qualified ATEX personnel authorized to do so by

the operator. The local electrical operating conditions and

local regulations (e.g., DIN, VDE) must be observed.

WARNING

Mains connection for explosion-proof motors

A mains connection in a potentially explosive atmosphere

requires a motor circuit breaker or equivalent protective

device, such as a PTC thermistor with triggering device.

This must be indicated on the motor rating plate together

with release time tA.

WARNING

Damage to pump motor/pump

When establishing the electrical connection of the pump

motor, be mindful of the correct direction of rotation. The

direction of rotation must match the arrow on the motor.

6. Assembly

6.8 Lubrication line arrangement

When arranging the main lubricant lines and lubrication point lines,

observe the following instructions in order to ensure that the entire

centralized lubrication system functions smoothly.

To prevent cavitation and thus early failure of the gerotor pump unit,

ensure that the suction line is sufficiently large.

Only grounded steel tubing may be used.

The suction line and thus the suction performance should be kept

to a minimum and the admission pressure must not exceed max.

0.2 bar.

The main lubricant line must be dimensioned in accordance with the

maximum operating pressure occurring in the lubrication unit used

and the displacement of that lubrication unit. If possible, the main

lubricant line should rise upward from the gerotor pump and be

ventable at the highest point on the lubrication line system.

Lubricant feeders at the end of the main lubricant line must be in-

stalled such that the outlets of the lubricant feeders point upwards.

If the system configuration requires that the lubricant feeders be

arranged below the main lubricant line, they should not be placed at

the end of the main lubricant line.

The pipes, hoses, shutoff valves, directional control valves, fittings,

etc. that will be used must be designed for the maximum operating

pressure of the lubrication unit, the permissible temperatures, and

the lubricants that will be delivered. The lubrication line system also

needs to be protected from excessive pressure by means of a pres-

sure-limiting valve. The use of plastic tubing may cause electrostatic

6.7.1 Establishing grounding connection

for motor

)See Figures 15 to 17 and Fig. 18

The product has ports for one protective earth conductor and one to

two equipotential bonding connections.

The port for the protective earth conductor is located in the motor’s

terminal box (1) and is intended for the electrical line and the electri-

cal connections.

Depending on the motor size, there are one or two equipotential

bonding connections attached to the motor housing (see Figs.

15/16, position “- EK” and Fig. 19 (2) (3)).

The gerotor pump unit must be connected to the equipotential

bonding of the main machine using the provided equipotential

bonding ports.

• Establish equipotential bonding using the provided equipotential

bonding ports (2) (3) to the main machine.

In case of terminal clamps with cable lugs, select their size according

to the required conductor cross-section and the bolt size. Installation

in a slanted position is permissible only if the required air and creep-

age distances are maintained.

Strip conductor ends so that the remaining insulation extends al-

most to the cable lug.

The current-carrying connection is ensured by direct contact be-

tween the cable lug surfaces and the contact nut or contact screw.

WARNING

Hazardous contact voltages on unit

The protective earth conductor (in the motor terminal

box) and the equipotential bonding (on the motor hous-

ing) must always be connected. Ensure that the contact

is secure and that the connector diameter is adequate

and standard-compliant.

charges. Stainless steel tubing is recommended to achieve sufficient

equipotential bonding.

All components of the lubrication line system such as pipes, hoses,

shutoff valves, directional control valves, fittings, etc. must be care-

fully cleaned before assembly. No seals in the lubrication line sys-

tem should protrude inwards in a way that disrupts the flow of the

lubricant and could allow contaminants to enter the lubrication line

system.

Lubrication lines should always be arranged so that air pockets can-

not form anywhere. Avoid changes in the cross-section of the lubri-

cation line from small to large cross-sections in the direction of flow

of the lubricant. When the cross-section does change, the transition

should be gentle.

The flow of lubricant in the lubrication lines should not be impeded

by the incorporation of sharp bends, angle valves, or flap valves.

Unavoidable changes in the cross-section in lubrication lines must

have smooth transitions. Sudden changes of direction should be

avoided if possible.

6.9 Lubrication line connection

The lubrication line must be connected to the lubrication unit in such a way that no forces can be transferred to the assembled lubrication unit (stress-free connection).

The fittings used to connect the lubrication line should be rated for

the maximum operating pressure of the lubrication unit.

For operating pressures up to 45 bar as can occur especially in

single-line piston distributor systems, SKF fittings for solderless pipe

unions can be used (double tapered sleeves or tapered sleeves). For

higher operating pressures up to 250 bar as can occur especially

in progressive centralized lubrication systems, SKF cutting-sleeve

screw unions conforming to DIN 2353 can be used. If using fittings

from other manufacturers, pay careful attention to the assembly in-

structions and technical specifications provided by the manufacturer.

WARNING

Environmental pollution

Lubrication lines must always be free of leaks. Lubricants

can contaminate soil and waterways. Lubricants must be

used and disposed of properly. Observe the local regula-

tions and laws regarding the disposal of lubricants.

6.10 Note on the rating plate

)See Figure 19

The rating plate provides important data such as the type designa-

tion, order number, barcode, and serial number.

To avoid loss of this data in case a rating plate becomes illegible,

these characteristics should be entered in Figure 20.

• Enter characteristics from rating plate in Figure 19.

7. Commissioning, operation


WARNING

To ensure safety and functionality, the person speci-

fied by the operator is required to inspect certain

areas of the centralized lubrication system prior to

initial commissioning. Any detected deficiencies must

be reported immediately to the supervisor and rem-

edied prior to initial commissioning.

The correction of deficiencies must be done exclu-

sively by a specialist in maintenance/servicing in po-

tentially explosive atmospheres.

No potentially explosive atmosphere may be present

during initial commissioning.

7.1 Commissioning

IMPORTANT NOTE

Different lubricants must not be mixed together. Doing so can

cause damage and require costly and complicated cleaning of the

gerotor pump unit/the lubrication system.

It is recommended that an indication of the lubricant in use be at-

tached to the lubricant reservoir (provided by customer) in order

to prevent accidental mixing of lubricants.

WARNING

Hazard due to excessively low or no lubricant

The gerotor pump unit may only be commissioned

and operated with an oil supply; the gerotor pump must

not run dry.

The lubricant fill level in the lubricant reservoir should be

subjected to visual inspection on a regular basis.

Inspect all electrical and hydraulic connections before initial com-

missioning of the gerotor pump unit.

The intake and return lines in the lubricant reservoir must be below

the minimum lubricant level in all operating states.

• Place an oil tray under the gerotor pump unit.

• -See operating instructions from system manufacturer, Chapter

“System ventilation”

• Prefill the pump unit with filtered lubricant via the suction or

pressure port.

• Vent the pump unit according to the operating instructions from

the system manufacturer.

If switchable or automatic venting is not available, the gerotor pump

unit must be manually vented as described below.

• Switch the centralized lubrication system to pressureless circula-tion mode according to the operating instructions from the sys-tem manufacturer.

• Disconnect the pressure port.

• Prefill the gerotor pump unit with oil via the pressure port and

briefly switch the unit on and off in jogging mode.

• Repeat the procedure until bubble-free lubricant discharges.

• Firmly reconnect the pressure port.

The process of venting the centralized lubrication system can be

facilitated by filling long pipe sections before connecting to the lubri-

cation point.

• Allowing the gerotor pump unit to run until bubble-free and

foam-free lubricant discharges at the end of the lubricant lines.

Ensure that the pump does not run dry in the process.

• Turn off the gerotor pump unit.
