Reprime pump, check that pump and suc-
tion line are full of liauid.

Suction line cloqqed.

Remove obstructions.

Impeller cloqqed with foreiqn material.

Back flush pump to clean impeller.

Wrong direction of rotation.

Change rotation to concur with direction
indicated by arrow on bearing housing or
pump casing.

Foot valve or suction pipe opening not
submerqed enouqh.

Consult factory for proper depth. Use baf-
fle to eliminate vortices.

Suction lift too hiqh.

Shorten suction pipe.

No liquid delivered {3796)

Vent line not connected.

Pipe in vent line to expel air.

Pump not producing rated flow or
head.

Air leak thru oasket.

Replace oasket.

Air leak thru stuffinq box

Replace or readjust packinq/mechanical
seal.

Impeller partly cloqqed.

Back flush pump to clean impeller.

Excessive impeller-to-casino clearance.

Adjust impeller clearance.

Insufficient suction head.

Ensure that suction line shutoff valve is
fully open and line is unobstructed.

Worn or broken imoeller.

lnsoect and reolace if necessarv.

Pump starts then stops pumping.

Improperly primed pump.

Reprime pump.

Air or vapor pockets in suction line.

Rearranqe pipinq to eliminate air pockets.

Air leak in suction line.

Repair {plua) leak.

Pump is noisy or vibrates.

Improper pump/driver alionment.

Alion shafts.

Partly cloqqed impeller causinq imbal-
ance.

Back-flush pump to clean impeller.

Broken or bent impeller or shaft.

Replace as required.

Foundation not rigid.

Tighten hold down bolts of pump and mo-
tor or adjust stilts.

Worn bearinos.

Replace.

Suction or discharge piping not anchored
or properly supported.

Anchor per Hydraulic Institute Standards
Manual recommendations

Pump is cavitatino.

Locate and correct system problem.

Excessive leakage from stuffing box.

Packinq qland improperly adjusted.

Tiqhten qland nuts.

Stuffinq box improperly packed.

Check packinq and repack box.

Worn mechanical seal parts.

Replace worn parts.

Overheatina mechanical seal.

Check lubrication and coolina lines.

Shaft sleeve scored.

Remachine or replace as reauired.

Motor requires excessive power.

Head lower than rating. Pumps too much
liquid.

Consult factory. Install throttle valve, trim
impeller diameter.

Liauid heavier than expected.

Check specific aravitv and viscositY.

Stuffinq box packinq too tioht.
