Low output volume, erratic flow or no flow.
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
y
hose.
Check for pump cavitation - suction pipe should be sized
y
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.
Check all joints on the inlet manifolds and suction con-
y
nections. These must be air tight.
Inspect the pump for solid objects lodged in the dia-
y
phragm chamber or the seat area.
