handling.

1-2 Cautions for Use Condition

Caution

The pump should not be used other purpose except for liquid injection, otherwise, accident ordamage may be occurred.The pump should never be used for kinds of liquids which caused liquid end parts to be damaged.Please keep as followings or may be caused trouble.

- Ambient temperature : 0~40℃- Temperature of handling liquid : 0~80℃- Viscosity of handling liquid : 1~30cp- Improper liquid to use :

Liquid included particles as like Fe, Ni etc. affecting magnet. Organic solvent liquid to expand PP material obviously and slurry liquid .

1-3 Cautions for Installation

Warning

Install the pump at place not touch by outsider or children except authorized person.Do not touch with wetted hand. Electric shock may be occurred.

Caution

Do not install the pump in place which ambient temperature is high (above 40℃) or lowsdown below freezing point, pump internal may be damaged.Do not install pump in place with heavy moisture and dust. Electric shock and trouble maybe caused.Install suction side of pump at lower place than liquid level of tank because of not self-suction.Check voltage constant and frequency of moter prior to wiring, and connet to specifiedpower.Electric shock may be occurred unless earthing to earth line, connect to earth line certainly.Entrust to electrical technician for wiring.Install specified magnetic switch and thermal relay to control and maintenance, etc. of pump.Do use standardized good for wiring and be carefully safety in accordance with technicalstandard and wiring regulations.Please check out if the motor is being rotated correctly by accurate wiring connection.If the motor is rotated backward, it can be a cause of pump damage.

8 Principle of Operation

As indicated in the figure, the impeller embedded the

magnet(impeller) is rotated by the magnet (driving)

attached to the motor shaft. It is called a magnet driven

pump. The pump chamber is mainly composed of a

polypropylene(PP) and isolated from the exterior. There

is no need of a pump shaft and mechanical seals

because of the rotation of the impeller by the magnets,

not by the motor.

9-1 Place of Installation

Warning

Install the pump at place not to touch by outsider or children except authorized person.

Caution

Do not install the pump in place which ambient temperature is high (above 40℃) or lows downbelow freezing point, pump internal may be damaged.Do not install pump in place with heavy moisture and dust. Electric shock and trouble may becaused.Install suction side of pump at lower place than liquid level of tank because of not self-suction.

Install pump at easy place for maintenance and inspection. In case of pump installs at higher than level of tank, foot valve attaches on suction side and liquid shouldbe filled up in pump head prior to operation.

9-2 Piping

Caution

Use special heat-proof hose for transfer of liquid of high temperature.

Use corrosion resistance as like vinyl hose for piping of hose type and use flange of plasticseries for MX-135, 250, 300. Especially hose type uses wired hose(blade hose) to protectdistortion by suction pressure. Use hose band on connection part of hose for hose type and insert gasket and fully tighten

with bolts between flange not to leak liquid. Especially in case of connecion on suction sideis not safe, drop off capacity of pumping up.Shorten length and do not bend piping to reduce friction resistance of liquid.

9-4 Wiring

Warning

Do not touch with wetted hand. Electric shock may be odcurred.

Caution

Check Voltage constant and frequency of motor prior to wiring, and connet to specificatedpower.Electric shock may be occurred unless earthing to earth line, connect to earth line certainly.Install specified magnetic switch and thermal relay to control and maintenance, etc. of pump.Do use standardized goods for wiring and be carefully safety in accordance with technicalstandard and wiring regulations.Please check out if the motor is being rotated correctly by accurate wiring connection.If the motor is rotated backward, it can be a cause of pump damage.

Warning

Do not empty operation. Internal parts may be damaged.

Caution

In case of using a dangerous liquid, be sure to wear safety equipments like gloves, gogglesand mask, etc.Some water may be remained in pump head after final performance test.Remove the water in pump head and dry the pump necessarily, to avoid the problem thatmay be caused by abnormal phenomena of some liquid which may be occurred by areaction with water.Do not touch with bare hand on motor part when operation.A burn caused by high temperature may be occurred.Do not suddenly open and close for valves of suction and discharge. Impellar can not be rotated due to confusion of magnetic polarities.

Fill water up in pump room, close valve on discharge side, power on, and then open valve slowly. (Fill water up in suction hose and pump room and then power on in case of using foot valve.)

Check transfer of liquid without malfunction of pump. If not transfer immediately power off and removethe cause.Do not insert alien material in pump. If insert alien material, impellar may be locked. Motor rotateswithout transfer at case of lock, immediately power off and please remove alien material afterdisassemblying of pump.
