Symptom Cause Remedy
The foundation is not rigid. Tighten the hold-down bolts of
the pump and motor. Make sure
the baseplate is properly grout-
ed without voids or air pockets.
The bearings are worn. Replace the bearings.
The suction or discharge pip-
ing is not anchored or properly
supported. Anchor the suction or discharge
piping as necessary according
to recommendations in the Hy-
draulic Institute Standards Man-
ual.
The pump is cavitating. Locate and correct the system
problem.
The mechanical
seal is leaking ex-
cessively. The packing gland is not ad-
justed properly (some mod-
els). Tighten the gland nuts.
The stuffing box is not packed
properly. Check the packing and repack
the box.
The mechanical seal parts are
worn. Replace the worn parts.
The mechanical seal is over-
heating. Check the lubrication and cool-
ing lines.
The shaft or shaft sleeve is
scored (some models). Machine or replace the shaft
sleeve as necessary.
The motor re-
quires excessive
power. The discharge head has drop-
ped below the rated point and
is pumping too much liquid. Install a throttle valve. If this
does not help, then trim the im-
peller diameter. If this does not
help, then contact your ITT rep-
resentative.
The liquid is heavier than ex-
pected. Check the specific gravity and
viscosity.
The stuffing-box packing is too
tight. Readjust the packing. If the
packing is worn, then replace
the packing.
Rotating parts are rubbing
against each other. Check the parts that are wearing
for proper clearances.
The impeller clearance is too
tight. Adjust the impeller clearance.
7.2 Alignment troubleshooting
Symptom Cause Remedy
Horizontal (side-to-side) align-
ment cannot be obtained (an-
gular or parallel). The driver feet are bolt-
bound. Loosen the pump's hold-down bolts, and slide the
pump and driver until you achieve horizontal align-
ment.
The baseplate is not
leveled properly and is
probably twisted. 1. Determine which corners of the baseplate are
high or low.
2. Remove or add shims at the appropriate cor-
ners.
3. Realign the pump and driver.
Vertical (top-to-bottom) align-
ment cannot be obtained (an-
gular or parallel). The baseplate is not
leveled properly and is
probably bowed. 1. Determine if the center of the baseplate
should be raised or lowered.
2. Level screws equally at the center of the
baseplate.
3. Realign the pump and driver.
