  If the motor of your Calpeda Water Pump doesn't start, several issues could be the cause. First, ensure the mains frequency and voltage are suitable. Verify the power supply cable is correctly connected. Check if the engine overload protective device has activated, and if so, examine the power supply and ensure the pump shaft turns freely.

  If your Calpeda Water Pump has insufficient flow, it could be due to several reasons. Ensure that the pipes and accessories being used are suitable for the specific application. Clean the impeller and install a suction filter to address any deposits or solid bodies. If the rotor is deteriorated or worn, replace the impeller and the pump casing, respectively. For gases dissolved in the water, perform opening and closing maneuvers through the feeder gate. Note that the pump is unsuitable for liquids with excessive viscosity. Check and correct the direction of rotation by inverting the electrical connections in the terminal board.

  If there's leakage from the mechanical seal rings of your Calpeda Water Pump, ensure that the pump casing is full of liquid and that all the air has been expelled. Another cause could be mechanical seal rings scratched by abrasive parts in the pumped liquid, so install a suction filter.
