REMEDIES
The pump inlet should be
piped to induce minimal pres-
sure drops through piping
diameter changes, elbows,
instrumentation, etc. QSV
pumps should NEVER be
throttled at the inlet. Check
discharge screen for
obstructions.
Verify no debris is clogging
screen or filter.
Make sure the discharge
valve is open enough to keep
the pump running on the per-
formance curve.
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.
POSSIBLE CAUSES
Restrictions in the inlet or
discharge
Inlet strainer/filter plugged
Discharge throttling valve
closed (pump deadheaded)
Air leak in inlet piping
PROBLEM
Low flow
