    AM SERIES 5. Notes for Operation 5.1 Dry-Running (1) Our pump use the transfer fluid as its internal cooling system, therefore, dry-running the pump can cause the temperature to rise to a dangerous level that may seriously damage the pump.

  • Page 14: Operating Procedure And Notes

    AM SERIES Should foreign matter enter the pump, it may cause pump damage or failure. Turn off the power at once and remove the obstruction. 5.5 Minimum Flow Our pump uses the pumped fluid as its cooling and lubricating system. A low flow rate may result in increasingly high temperature within the pump, and increased radial and axial force, thus, affecting the pump’s performance and service life.

    AM SERIES (3) During power outages, shut off the pump’s power supply and close the outlet valve. (4) When switching on the pump with the outlet valve closed, the outlet pressure should increase. If the pressure fails to rise, or if the pressure is too low, shut down the pump and check the piping and wiring.
