 TROUBLE SHOOTING

Product discharged from exhaust outlet.

 

y

Check for diaphragm rupture.

 

y

Check tightness of diaphragm nut.

Air bubbles in product discharge.

 

y

Check connections of suction plumbing.

 

y

Check “O” rings between intake manifold and fluid caps.

 

y

Check tightness of diaphragm nut.

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 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-

phragm chamber or the seat area.
