Tips

for trouble-free operation

9.3

Pump Overloads Motor

9.4

Abnormal Vibrations of Pumping Equipment

Possible Causes

Solutions

1.-

The pumped liquid has a viscosity or density

different from that for which the pump was

selected.

Check and consult the
manufacturer.

2.-

There are mechanical defects (moving parts

rubbing against fixed parts).

Check and consider a pump repair.

1.-

The pump is not primed.

Possible Causes

Solutions

2.-

Air enters the suction pipe.

Check and complete the filling of the system with

liquid.

Check and repair damaged ducts and

defective joints.

3.-

The suction lift is too high (insufficient NPSH).

Check that NPSHavailable > NPSHrequired

Check suction geometric height.

Check head losses in the suction pipe (partially

closed valve, foreign bodies).

4.-

The impeller is partially clogged causing

unbalance.

Check and unclog obstructions.

Check that the bearings are not damaged.

5.-

There are mechanical problems, such as bent

shaft, seized parts.

Check and consider repair.

9.5

Pump Breaks Down After Start-up

Possible Causes

Solutions

1.-

Leaks in the suction line.

Check and repair damaged ducts and

defective joints.

2.-

The suction height is too high.

Check suction height and consult the

manufacturer.

3.-

The foot valve or pipe is not sufficiently

submerged.

Check and submerge as necessary.
