What to do if the discharge capacity of my IWAKI PUMPS MX is too low?
- M
  Misty GarciaAug 1, 2025
  If the discharge capacity is too low, several factors could be responsible: * The strainer may be clogged with foreign matter: Remove the foreign matter. * There could be an air pocket in the suction line: Check and correct the suction line. * Foreign matter may be clogging the impeller inlet: Remove the foreign matter. * Air may be entering from a suction line or sealing surface: Check the suction line connections and retighten if needed. * The discharge line may be clogged with foreign matter: Remove foreign matter or scale from the pump/piping. * There may be resistance, such as an air pocket in the suction line: Check for arched pipework. * The actual head may be too high, or pipe resistance may be too large: Check the actual head and pipe resistance.

  If the pressure drops sharply after starting when you open a discharge valve, check these: * Air ingress: Ensure suction line connections are completely sealed to prevent air from entering. * Magnet coupling: Check the amperage to see if the motor is overloaded. * Impeller or magnet capsule: Check if foreign matters do not lock the impeller or magnet capsule. * Voltage: Check if voltage is normal.

  Brooke AllenAug 18, 2025
  If the pump isn't discharging liquid: * Check the priming liquid level: If it's too low, stop the pump, prime it, and then resume operation. * Inspect the foot valve: If it's clogged with foreign matter, clean both the foot valve and its seat.

Why is the discharge capacity of my IWAKI PUMPS MX Water Pump rapidly reducing?
- J
  Jason VelezAug 23, 2025
  If the discharge capacity is rapidly reducing, it may be because a suction line is clogged with foreign matter. Remove any foreign matter to resolve this issue.

Why is the pressure low and vacuum very low in my IWAKI PUMPS Water Pump?
- K
  Kevin BellAug 27, 2025
  If the pressure is low and the vacuum is very low, it's possible that the motor is rotating in reverse. To correct this, interchange the motor wiring.
