Why does my Tsurumi Pump HS3.75S start but stop?

  Joshua DavisAug 4, 2025
  If your Tsurumi Pump Water Pump starts but then stops, several factors could be at play. The motor windings or cable might be damaged, so check them. An impeller could be blocked or choked. Also, wrong voltage or frequency could be the reason. Check the voltage under load if it seems too low. If a generating set provides power, the frequency may be inexact. Excessive viscosity or density of the liquid could also be the reason. Finally, there might be a wrong setting or thermal overload at the power source.

  If your Tsurumi Pump Water Pump fails to start, there are a few things to check. If a level control exists, ensure it's calling for the pump to start. Use a multimeter, portable lamp, or electric tool to verify power availability. Remove the pump casing and confirm that the impeller rotates freely and without noise. At the pump cable's end, check the insulation value of the earth lead (it should be over 20 M Ohm) and the winding's continuity.

What to do if Tsurumi Pump Water Pump head and flow are lower than expected?

  Ashley AllisonAug 13, 2025
  If your Tsurumi Pump Water Pump's head and flow are lower than originally, several issues could be responsible. There might be a restriction in the piping or excessive resistance in the discharge conduit (perhaps it's too high, too long, too small, or dirty inside). The impeller could be worn, partially choked, or severely narrowed by hard deposits. The strainer or inlet might be blocked, or the pump could be drawing air. Also, the liquid might be partly volatile or contain a high level of gas in solution.

Why does my Tsurumi Pump Water Pump generate noise or vibration?

  Leslie RobinsonAug 16, 2025
  If your Tsurumi Pump Water Pump generates unusual noise or vibration, it could be due to a few reasons. The impeller might be severely damaged, or a bearing could be failing. Repair it at once. Also, check that the pump isn't lying on its side and drawing air. This could also indicate a high wear rate.
