  Thomas FloresAug 7, 2025
  If your Teral Water Pump doesn't start, several issues could be the cause. First, check the wiring and connections for any disconnections or breaks, and repair or replace as needed. Also, verify if the power fuse is blown and replace it with an appropriate fuse if necessary. Additionally, check the thermal relay and ensure the power voltage is not too low; if it is, contact the power company. Poor connection of power wires can also prevent starting, so ensure they are properly connected.

  If your Teral Water Pump starts but doesn't reach the specified discharge rate and head, several factors could be responsible. Make sure the sluice valve is fully open. Check the piping for any clogs caused by foreign matter, and clean it thoroughly. Also, inspect the strainer in the suction port for clogs and clean it as necessary. Ensure that the suction port is not exposed above the liquid level; if it is, replenish the liquid or lower the pump's mounting position. Finally, check the discharge pipe for any leaks and repair them.

  Christopher McdonaldAug 16, 2025
  If the motor of your Teral Water Pump experiences overload and overcurrent, there are several potential causes. Begin by checking the power voltage to ensure it's within the correct range; if it's too high or too low, contact the power company. Inspect the wiring for any open-phase failures. Ensure that the liquid you are using does not have a high dynamic viscosity; if it does, switch to a liquid with lower viscosity. If the discharge rate is too high, throttle the sluice valve to meet the specifications. Also, check the rotating speed with a tachometer.

  Tanya DavisAug 20, 2025
  If your Teral Water Pump starts but fails to achieve the specified discharge rate and head, consider these potential causes. First, ensure that the liquid being used does not contain excessive air bubbles and prevent the suction of air bubbles. Verify that the rotation direction is correct by checking the wiring. Inspect the piping for high losses, examining the diameter, route, and length. Also, check for any foreign matter clogging the piping and remove it, ensuring all connections are clear. Check the rotating speed with the tachometer.
