OPERATION
GENERAL CONSIDERATIONS AND REVIEWS
Always vary capacity with regulating valve in the
discharge line. NEVER throttle flow from the suction
side.

For ball bearings and sleeve radial/ball thrust bearing
check oiler to insure proper level.
Driver may overload if the pumped fluid specific
gravity is greater than orig
Always operate the pump at or near the rated prevent damage resulting from cavitations or recirculation.

CAUTION
OPERATING AT REDUCED CAPACITY

CAUTION
Damage occurs from:
1- Increased vibration levels -Affects bearings, seal
chambers/stuffing boxes, and mechanical seals.
2-Increased radial load -Stresses on shaft and bearings.
3-Heat build up -Vaporization causing rotating parts to
score or seize.
4. Cavitation -Damage to internal surfaces of pump.
1- Check bearing temperatures using a pyrometer or
other accurate temperature measuring device.
Monitor bearing temperature frequently during initial
operation to determine if a bearing problem exists as
well as to establish normal bearing operating
temperature.
2- On units equipped with auxiliary piping, assure that
proper flows have been established and that
equipment is operating properly.
3- Baseline vibration readings should be established to
determine normal running conditions. If it is
determined that the unit is running rough, consult
factory.
4- Monitor all gauges to ensure pump is running at or
near rating and that suction screen (when used) is not
clogged.
�
CAUTION
The following are minimum operational checks for the
pump only. Consult driver and auxiliary equipment
manufacturers’ literature for additional information.
