TROUBLE SHOOTING
Product discharged from exhaust outlet.
yCheck for diaphragm rupture.
yCheck tightness of (6) diaphragm screw.
Air bubbles in product discharge.
yCheck connections of suction plumbing.
yCheck “O” rings between intake manifold and fluid caps.
yCheck tightness of (6) diaphragm screw.
Motor blows air or stalls.
yCheck (176) check valve for damage or wear.
yCheck for restrictions in valve / exhaust.
Low output volume, erratic flow or no flow.
yCheck air supply.
yCheck for plugged outlet hose.
yCheck for kinked (restrictive) outlet material hose.
yCheck for kinked (restrictive) or collapsed inlet material hose.
yCheck 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
yCheck all joints on the intake manifolds and suction con- nections. These must be air tight.
yInspect the pump for solid objects lodged in the dia- phragm chamber or the seat area.
