CAUTION

  Never run pump dry or shut off a suction valve during operation. Otherwise the pump 

fails in a short period.

  Check the rotational direction of the pump. Clockwise seen from the motor end is a 

correct direction. Operation in the reverse direction may cause pump damage. Always 
carry out rotation check with the pump full of liquid.

  Stop the pump within one minute if cavitation occurs.

  Do not run the pump when air enters the suction line.

  Stop the pump immediately when the magnet coupling is disconnected. The magnet 

force reduces if the pump keeps on running for more than one minute in this condition.

  The maximum number of ON/OFF operation should be within six times an hour. 

Frequent ON-OFF operation can reduce the pump life.

  Keep liquid temperature change within 80

˚

C through operation and stopping.

  Start the pump with a discharge valve full close in order to avoid water hammer.

  Closed-discharge operation should be within one minute. If the pump runs with a dis-

charge valve closed for a long time, the liquid temperature inside the pump rises and 
it damages the pump.

  If power is interrupted when the pump is running, switch off and close a discharge 

valve.

  Take extra care so that the discharge pressure does not exceed the pump limit.

  When high temperature liquid is transferred, the pump surface becomes very hot. 

Take a protective measure against burn. See below.

Liquid temperatuer

Surface temperature

80°C

75°C

  Noise level is 90dB (A scale - one meter)

In case the pump noise affects human health or the communication to secure a safety, 
provide a noise reduction cover. Be careful not to reduce cooling effect by a motor fan.
