TROUBLE SHOOTINGProduct discharged from exhaust outlet.
SCheck for diaphragm rupture.
SCheck tightness of (6) diaphragm washer.
Air bubbles in product discharge.
SCheck connections of suction plumbing.
SCheck “O” rings between intake manifold and inlet side fluid caps.
SCheck tightness of (6) diaphragm washer.
Motor blows air or stalls.
SCheck (176) check valve for damage or wear.
SCheck for restrictions in valve / exhaust.
Low output volume, erratic flow, or no flow.
SCheck air supply.
SCheck for plugged outlet hose.
SCheck for kinked (restrictive) outlet material hose.
SCheck for kinked (restrictive) or collapsed inlet material hose.
SCheckfor pump cavitation -- suction pipe should be sized at least as
largeas the inlet thread diameter of the pump for proper flow if high
viscosityfluids are being pumped. Suction hose must be a non-col-
lapsing type, capable of pulling a high vacuum.
SCheck all joints on the inlet manifolds and suction connections.
These must be air tight.
SInspectthe pump for solid objects lodged in the diaphragm chamber
or the seat area.
