Check tightness of (14) diaphragm screw.
Air bubbles in product discharge.

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 ow if high viscosity uids 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 connections.
These must be air tight.
Inspect the pump for solid objects lodged in the diaphragm
chamber or the seat area.
