Alarko Circulation Pumps are developed for the heating and water circulation systems for houses, commercial andindustrial applications. These high technology products are born out of an industrial experience of half a century.
Connect the pump to the installation as shown in the figure by making it parallel to the ground.
Use isolating valves in the inlet and outlet in order to facilitate the removal of pump during repair or
maintenance.
Use a thermic relay when connecting the pump to electric supply.
INSTALLATION POSITIONS
CORRECT OPERATION
✓
✓
✓
When there is cavitation in a circulation pump, the following problems arise:Low performance: Since the required flow conditions are not met, pumpcannot create the necessary flow rate and pressure. Upper floors cannot beheated.Vibration: Turbulent flow caused by air bubbles causes vibration.Pump life is reduced: Air bubbles in the system or in the pump corrode thepump material causes erosion.Noise: Air bubbles, turbulence and striking of water on surfaces create noise.
PERMITTED
Pump shaft must be parallel position.
NOT PERMITTED
Pump shaft must not be vertical position.
When the pressure at the suction end ofthe circulation pump is not enough, waterchanges phase to turn into gas. Gasbubbles are carried to high pressure areasby the flow. Vapour turns into water againand gas bubbles causes turbulence in theflow and water strikes the surfaces. Thisprocess is called cavitation.
Do not operate the pump without water.NEVER LUBRICATE THE PUMPRods and bearings of ALARKO circulation pumps are water lubricated and they do not needmaintenance. New or idle pump rods may be throttled due to the pollutants and particles inthe water. In such cases, close the main electric switch. Remove the rotor end cap and rotatethe shaft a few rounds via screwdriver. Put the rotor end cap in place and operate the pump.Single speed pumps can be modified into three speed pumps by way of an adaptor. Notify thisin your orders.

It is essential to know the flow rate (Q) and necessary pressure (Hm) value for the selection of circulationpump. These values are given in the heating project of the building and circulation pump selection ismade according to these values. If no heating project is available, the following evaluation methods canbe applied for pump selection.
Evaluation of the Necessary Flow Rate (Q)The pump should be able to carry the heated water from the boiler to the radiators with a suitable flowrate. Flow rate is determined using the formula below;
Q : Necessary pump flow rate (m3/hour)
Qk : The capacity of the boiler (kcal/hour)
Tg : The temperature of water flowing out of the boiler (°C)
Td : The temperature of water returning to the boiler (°C)
QkQ = (Tg – Td) x 1.000
Evaluation of the Required Pressure (Hm)The pump should have sufficient pressure to be able to push the water to the most distant point of theinstallation by defeating the resistance of the heating installation. Here, the pump should defeat thetotal pressure that is caused by the resistance of the pipes, connection components, valves, radiators.While the same water height will be at the inlet and outlet of the pump, the height of the building hasno effect to the pump selection procedure.
H : Pump pressure (mWc)
R : Pressure loss per square meter at pipe diameter (mWc/meter)
L : Total lengths of pipe components in the installation (meter)
Z : Resistance of connection components, valves and special devices (mWc)
H ≥ ∑ (R x L) + ∑ (Z)
If the project of the building is not available, it is almost impossible to determine correctly the valuesmentioned above.In this case, following tables can be used to determine the required pressure approximately.

It is essential to know the flow rate (Q) and necessary pressure (Hm) value for the selection of circulationpump. These values are given in the heating project of the building and circulation pump selection ismade according to these values. If no heating project is available, the following evaluation methods canbe applied for pump selection.
Evaluation of the Necessary Flow Rate (Q)The pump should be able to carry the heated water from the boiler to the radiators with a suitable flowrate. Flow rate is determined using the formula below;
Q : Necessary pump flow rate (m3/hour)
Qk : The capacity of the boiler (kcal/hour)
Tg : The temperature of water flowing out of the boiler (°C)
Td : The temperature of water returning to the boiler (°C)
QkQ = (Tg – Td) x 1.000
Evaluation of the Required Pressure (Hm)The pump should have sufficient pressure to be able to push the water to the most distant point of theinstallation by defeating the resistance of the heating installation. Here, the pump should defeat thetotal pressure that is caused by the resistance of the pipes, connection components, valves, radiators.While the same water height will be at the inlet and outlet of the pump, the height of the building hasno effect to the pump selection procedure.
H : Pump pressure (mWc)
R : Pressure loss per square meter at pipe diameter (mWc/meter)
L : Total lengths of pipe components in the installation (meter)
Z : Resistance of connection components, valves and special devices (mWc)
H ≥ ∑ (R x L) + ∑ (Z)
If the project of the building is not available, it is almost impossible to determine correctly the valuesmentioned above.In this case, following tables can be used to determine the required pressure approximately.

SELECTION OF THREADED THREESPEED CIRCULATION PUMPSFor Q= 1,5 m3/h, H= 5 mWcA vertical line is drawn from point1,5 of the Q axis of the “GeneralSelection Chart for Threaded ThreeSpeed Circulation Pumps”. Ahorizontal line is drawn from point5 of the H axis. The intersection ofthese lines is marked as (A). PointA belongs to the pump type NPVO63-32 P. After choosing this pumptype, it is necessary to determinethe speed of the pump by referringto the “Independent CharacteristicCurves for Threaded Three SpeedCirculation Pumps”. Point A on thecurve of the 63/32 P type is marked.For the values in the example, pointA is between the speed curves IIand III. This is a suitable choice.

It is essential to know the flow rate (Q) and necessary pressure (Hm) value for the selection of circulationpump. These values are given in the heating project of the building and circulation pump selection ismade according to these values. If no heating project is available, the following evaluation methods canbe applied for pump selection.
Evaluation of the Necessary Flow Rate (Q)The pump should be able to carry the heated water from the boiler to the radiators with a suitable flowrate. Flow rate is determined using the formula below;
Q : Necessary pump flow rate (m3/hour)
Qk : The capacity of the boiler (kcal/hour)
Tg : The temperature of water flowing out of the boiler (°C)
Td : The temperature of water returning to the boiler (°C)
QkQ = (Tg – Td) x 1.000
Evaluation of the Required Pressure (Hm)The pump should have sufficient pressure to be able to push the water to the most distant point of theinstallation by defeating the resistance of the heating installation. Here, the pump should defeat thetotal pressure that is caused by the resistance of the pipes, connection components, valves, radiators.While the same water height will be at the inlet and outlet of the pump, the height of the building hasno effect to the pump selection procedure.
H : Pump pressure (mWc)
R : Pressure loss per square meter at pipe diameter (mWc/meter)
L : Total lengths of pipe components in the installation (meter)
Z : Resistance of connection components, valves and special devices (mWc)
H ≥ ∑ (R x L) + ∑ (Z)
If the project of the building is not available, it is almost impossible to determine correctly the valuesmentioned above.In this case, following tables can be used to determine the required pressure approximately.

CORRECT OPERATION

When there is cavitation in a circulation pump, the following problems arise:Low performance: Since the required flow conditions are not met, pumpcannot create the necessary flow rate and pressure. Upper floors cannot beheated.Vibration: Turbulent flow caused by air bubbles causes vibration.Pump life is reduced: Air bubbles in the system or in the pump corrode thepump material causes erosion.Noise: Air bubbles, turbulence and striking of water on surfaces create noise.
PERMITTED
Pump shaft must be parallel position.
NOT PERMITTED
Pump shaft must not be vertical position.
When the pressure at the suction end ofthe circulation pump is not enough, waterchanges phase to turn into gas. Gasbubbles are carried to high pressure areasby the flow. Vapour turns into water againand gas bubbles causes turbulence in theflow and water strikes the surfaces. Thisprocess is called cavitation.
Do not operate the pump without water.NEVER LUBRICATE THE PUMPRods and bearings of ALARKO circulation pumps are water lubricated and they do not needmaintenance. New or idle pump rods may be throttled due to the pollutants and particles inthe water. In such cases, close the main electric switch. Remove the rotor end cap and rotatethe shaft a few rounds via screwdriver. Put the rotor end cap in place and operate the pump.Single speed pumps can be modified into three speed pumps by way of an adaptor. Notify thisin your orders.
