TROUBLE SHOOTING
Product discharged from exhaust outlet.
y
Check for diaphragm rupture.
y
Check tightness of diaphragm nut.
Air bubbles in product discharge.
y
Check connections of suction plumbing.
y
Check “O” rings between intake manifold and uid caps.
y
Check tightness of diaphragm nut.
Low output volume, erratic ow, or no ow.
y
Check air supply.
y
Check for plugged outlet hose.
y
Check for kinked (restrictive) outlet material hose.
y
Check for kinked (restrictive) or collapsed inlet material
hose.
y
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-collapsing type, capable of
pulling a high vacuum.
y
Check all joints on the inlet manifolds and suction con-
nections. These must be air tight.
y
Inspect the pump for solid objects lodged in the dia-
phragm chamber or the seat area.
