Low output volume, erratic fl ow or no fl 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 fl ow if high viscosity fl uids are being pumped.
Suction hose must be a non-collapsing type, capable of
pulling a high vacuum.
Check all joints on the intake 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.
