Product discharged from exhaust outlet.



Check for diaphragm rupture.



Check tightness of (14) diaphragm washer.

Air bubbles in product discharge.



Check connections of suction plumbing.



Check O" rings between intake manifold and inlet side

fluid caps.



Check tightness of (14) diaphragm washer.

Motor blows air or stalls.



Check (176) check valve for damage or wear.



Low output volume, erratic flow, or no flow.



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 flow if high viscosity fluids are being

pumped. Suction hose must be a non-collapsing type,

capable of pulling a high vacuum.



Check all joints on the inlet manifolds and suction con-

nections. These must be air tight.



Inspect the pump for solid objects lodged in the dia-

phragm chamber or the seat area.
