PROBLEM

POSSIBLE CAUSES

REMEDIES

 

 

 

 

 

Low flow

Suction lift too high

QSV pumps are not designed

 

(continued)

 

to “lift” or “pull” fluid from a

 

 

 

tank. QSV pumps must be fed

 

 

 

with positive pressure [at

 

 

 

least 20 psi (1.4 bar)]. This

 

 

 

may be accomplished either

 

 

 

by having positive head from

 

 

 

the tank or incorporating a

 

 

 

transfer pump.

 

 

 

 

 

 

Reverse rotation of motor

Make sure the motor is spin-

 

 

 

ning in the proper direction.

 

 

 

 

 

 

Pump not adequately

Prime the pump by filling all

 

 

primed

inlet piping, including the

 

 

 

pump, with the process fluid.

 

 

 

 

 

 

Excessive flow

Make sure your pump is oper-

 

 

 

ating within the flow range

 

 

 

specified by the pump per-

 

 

 

formance summary table or

 

 

 

the performance curve

 

 

 

included with the pump.

 

 

 

 

 

 

Clogged suction into filter or

Verify no debris is clogging

 

 

screen

the inlet screen or filter.

 

 

 

 

 

 

Air leak in the inlet piping

Fluid motion in your inlet pip-

 

 

 

ing may draw air into the

 

 

 

pump if the piping is not

 

 

 

sealed properly. Air bubbles

 

 

 

will be visible in the discharge

 

 

 

line.

 

 

 

 

 

 

Reverse rotation of motor

Make sure the motor is spin-

 

 

 

ning in the proper direction.

 

 

 

Reverse two of the leads if

 

 

 

necessary.
