DAFA : Transfer Pump Runaway A

Refill or replace drum.

Condition material temperature per manufacturer's recommendations before spraying.

Inspect the transfer pump lower for wear or fatigue.

  • Worn seals can cause pump to run excessively fast and/or not generate the desired supply pressure.
  • A broken top pin in the pump lower will cause the pump to easily move in both directions without generating pressure
  • A broken bottom pin will cause the pump to only generate pressure while moving down.  The pump will easily move upward while not generating pressure
