Common Questions / Problems
The pump is failing to operate.
- Dirty or worn air motor; clean and service

Service & Repairs
Pump does not move
- Air motor stalled; close the needle valve and bleed down air pressure to the motor, if possible move the piston rod manaully a short distance and then close the bleed valve and slowly open the air needle valve to the air motor
- Springs are damaged; replace
- Low air supply; increase air supply with air regulator/open air needle valve/close bleed valve
- Fluid outlet is blocked; check downstream hoses or check for closed valves
Air leaks along piston shaft
- Worn packing; replace
Air leaks from piston shaft holes
- Contamination by debris in air motor piston; check and service
Slow air motor operations
- Icing of the air motor; allow the build-up to thaw
- Clogged muffler; clean or replace
Low output on both strokes
- Restricted hose access; clean, clear or replace
- Bad fluid seals foot valve or piston cup; replace
Low output on the upstroke
- Bad or damaged piston cup; replace
Low output on the downstroke
- Bad or damaged foot valve or ball; replace
Leaking fluid through packing at the air motor
- Packings damaged or not seated properly; replace or set the packings
- Packing nut too loose; tightening down the nut
- Scored or scratched displacement rod; replace
Abnormal or rapid operation
- Low or no fluid supply; replenish fluid supply and reprime the cup
- Broken spring in air motor; replace
Jerky movement of the pump
- Packing nut too tight; stop the pump operation, relieve fluid with the drain valve and loosen packing then re-tightening it

Service & Repairs
Pump does not operate
- Air supply or pressure is inadequate or the air lines are restricted; increase air pressure and check for any restrictions in the air line
- Dispensing valve is not open or it is clogged; open and/or clear valve
- Clogged fluid lines, valves, hoses, etc; follow the pressure relief procedure to clear obstruction
- Damaged air motor; service the air motor
- Depleted or exhausted fluid supply; refill fluid and prime the system or flush it
Non-stop air exhaust
- Worn or damaged air motor, gasket, packing, seal, etc; service the air motor
Erratic pump operation
- Intake valve or packings are worn; refill the fluid and prime the system
- Intake valve is not completely closed; clear the obstruction and service the pump
Low output on the upstroke
- Clogged or worn piston valve; clear the obstruction and service
Low output on the downstroke
- Clogged or worn intake valve; clear the obstruction and service
Low output on both strokes
- Restriction in air lines or pressure is too low; increase the air pressure or supply
- Closed or clogged valves; open or clear the valve
- Fluid supply is insufficient or exhausted; refill fluid and prime the system
- Obstructions in fluid lines, hoses, valves, etc; follow the relief procedure to clear the obstruction
