TROUBLE SHOOTING
Product discharged from exhaust outlet.
y
Check for diaphragm rupture.
y
Check tightness of (14) diaphragm screw.
Air bubbles in product discharge.
y
Check connections of suction plumbing.
y
Check “O” rings between intake manifold and inlet side
fluid caps.
y
Check tightness of (14) diaphragm screw.
Motor blows air or stalls.
y
Check (176) check valve for damage or wear.
y
Check for restrictions in valve / exhaust.
Low output volume, erratic flow or no flow.
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 flow if high viscosity fluids are being pumped.
Suction hose must be a non-collapsing type, capable of
pulling a high volume.
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.
