Why does my Tsurumi Pump Water Pump stop automatically?
- K
  Kelly PaulAug 14, 2025
  Your Tsurumi Pump Water Pump may be stopping automatically because: * The pump casing is filled with mud. * The voltage is too low. * The pump was operated dry for too long because the suction strainer of the bottom plate is clogged, or it's pumping too much mud. * A 50Hz pump is being operated at 60Hz. To resolve this: 1. Disassemble and clean the pump, detach the suction cover, remove the mud, and manually turn the pump. 2. Raise the voltage to the rated voltage. 3. Remove debris. 4. Check the nameplate and replace the pump or the impeller.
