TROUBLE SHOOTING
Product discharged from exhaust outlet.
Check for diaphragm rupture.
Check tightness of (6) diaphragm screw.
Air bubbles in product discharge.
Check connections of suction plumbing.
Check“O” rings between intake manifold and inlet side
uid caps.
Check tightness of (6) diaphragm screw.
Motor blows air or stalls.
Check (176) check valve for damage or wear.
Check for restrictions in valve / exhaust.
Low output volume, erratic ow, or no ow.
Check air supply.
Check for plugged outlet hose.
Check for kinked (restrictive) outlet material hose.
Check for kinked (restrictive) or collapsed inlet
material hose.
Check for pump cavitation − suction pipe should be
sized at least as large as the inlet thread diameter of
the pump for proper ow if high viscosity uids are
being pumped. Suction hose must be a non-collaps-
ing type, capable of pulling a high vacuum.
Check all joints on the inlet manifolds and suction
connections. These must be air tight.
Inspect the pump for solid objects lodged in the dia-
phragm chamber or the seat area.
