Trouble Shooting
Symptom
Fluid discharged from exhaust outlet
Air bubbles in fluid discharge.
Motor blows air out main exhaust when stalled
on either stroke.
Low fluid output volume.
Possible Cause
●
Ruptured Diaphragm (20)
●
Diaphragm Nut loose (4A)
●
Leak in suction side plumbing
●
Leak at Inlet Collar (4C)
●
Leak at Diaphragm Nut (4A)
●
U-cups inserted incorrectly, damaged, or
missing.
●
Ceramic valves damaged or contaminated
with debris (7).
●
Pilot valve not correctly oriented.
●
Low or blocked incoming air supply.
●
Outlet plumbing blockage.
●
Pump not primed.
●
Suction pipe too small or suction hose not
rigid (kinks or collapses).
●
Leak in inlet suction plumbing.
●
Pump blocked internally with debris.
* Add a a medium grade thread locking compound to the diaphragm rod threads.

Repair
●
Replace Diaphragm (20)
●
Tighten loose Diaphragm Nut (4A)*
●
Check connections of suction plumbing.
●
Check torque of Inlet Collar (4C)
●
Check torque of Diaphragm Nut (4A)
●
Check (2B & 2D) U-cups on major valve
spool.
●
Check (7) ceramic valves for debris or
damage.
●
Be certain to load the pilot valve in the
proper orientation per diagram found within
the center-body.
●
Check air supply.
●
Check for any obstruction in the outlet
plumbing.
●
The pump must be mounted vertically for
checks to properly work.
●
Check for pump cavitation - the suction
pipe should be sized at least as large as
the inlet thread diameter. The suction hose
must be rigid or non-collapsible.
●
Check all inlet plumbing for possible
suction leaks.
●
Inspect the pump for debris that could
block internal flow or foul checks.
