Ingersoll-Rand AD40A-X-X manual Trouble Shooting, Dimensional Data

TROUBLE SHOOTING

Product discharged from exhaust outlet.

SCheck for diaphragm rupture.

SCheck tightness of diaphragm nut.

Air bubbles in product discharge.

SCheck connections of suction plumbing.

SCheck “O” rings between intake manifold and fluid caps. S Check tightness of diaphragm nut.

Low output volume, erratic flow, or no flow.

SCheck air supply.

SCheck for plugged outlet hose.

SCheck for kinked (restrictive) outlet material hose.

SCheck for kinked (restrictive) or collapsed inlet material hose.

SCheck 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-col-

lapsing type, capable of pulling a high vacuum.

SCheck all joints on the inlet manifolds and suction connections.

These must be air tight.

SInspect the pump for solid objects logged in the diaphragm chamber or the seat area.
