- 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.

  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.
