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 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-
