Troubleshooting

Observation Cause Solution
  • Pump not operating
  • No power.
  • Restricted liquid discharge.
  • Piston drive disconnected.
  • Check to see that the power supply is on, and that all connections are sound
  • Open discharge valve.
  • Pump driver operating (cycling), but not pumping liquid.
  • Restricted liquid discharge.
  • Piston drive disconnected.
  • Check for closed valve, clogged discharge or any other obstruction.
  • Remove obstruction and restart pump.
  • Make sure drive rod is connected.
  • If separated at compression fitting, a replacement drive rod ferrule will be required. (Ferrules cannot be recrimped).
  • Driver cycles properly but pump not pumping liquid.
  • Plugged bottom intake.
  • Disconnect liquid discharge hose/pipe from pumps discharge tee. Hold latex glove (or other inflatable object) over discharge tee mouth. Seal with a tight grip. Allow pump to operate. Pull pump and raise out of mud.
  • Glove does not inflate or deflate as pump cycles.
  • Downhole drive rod may have been cut incorrectly.
  • Riser pipe string may have a leak.
  • Drive rod disconnected from drive motor.
  • Remove and re-cut or adjust rod length as per installation instructions.
  • Check pipe connections and check for cracks or leaks. Repair or replace compromised pipe or fittings.
  • Glove inflates more and more as pump cycles.
  • No liquid at pump intake (downhole) to pump.
  • Check to make sure that there is liquid to pump.
  • Glove inflates on up stroke and deflates on down stroke, and does not inflate more and more with every stroke.
  • Plugged intake
  • Raise pump
  • Foot valve assembly/pipe string not water tight.
  • With drive rod and drive piston out of riser pipe, fill riser pipe with water. Water drains out quickly.
  • Remove riser pipe and foot valve assembly and inspect, replace, and/or repair.
  • Water stays in riser pipe (and drive rod and drive piston have been deemed OK).
  • Foot valve assembly/pump intake clogged.
  • Remove riser pipe and foot valve assembly and inspect. Clean piston and foot valve. Raise pump out of mud.
  • Drive rod/drive piston assembly tough to remove from foot valve assembly riser pipe. Suction pull back.
  • Pump intake may be clogged.
  • Follow directions for clogged intake foot valve.
  • Pump driver moving erratically when operating.
  • Loose connections.
  • Downhole drive rod length incorrect.
  • Check all connections to be sure they are tight.
  • Check rod length and adjust as per installation instructions.
