. Bolt the gland to the seal chamber using the

Legacy Method (Star Pattern) according to
torque requirements specified in the pump
OEM. If they are not specified then tension the
bolts using the Legacy Method in even 1/4 turn

increments until a gland seal is achieved. Be
sure not to overtighten the gland bolts as this
may distort the gland and mating ring resulting
in seal leakage.

BEFORE STARTING THE EQUIPMENT

1

. Ensure the pump shaft is properly aligned at

the coupling with the motor.

2

. Check that all gland plate bolts and all screws

are securely fastened.

3

. Once the pump is reassembled, turn the shaft

by hand if possible to check for free rotation, if
not, recheck installation.

4

. Verify that all plumbing and piping plans for the

seal are connected and configured according
to best practice.

5

. Flood the pump, vent all air from the seal

chamber, and check the seal for leakage.

6

. Ensure all plumbing and venting are free of

obstruction and that the chamber is filled with
liquid. Check that all alarms connected to
auxiliary systems are properly functioning to
alert personnel if any issues arise.

Dry-running is a major cause for leakage
and/or failure of mechanical seals. It is
imperative that the seal chamber be
completely vented prior to startup and that
adequate lubrication is supplied to the seal.

7

. Start the pump per the pump manufacturer’s

recommendations, observe for proper
operation, and check for excessive heat at the
seal gland.

Check periodically during operation to
ensure that the seal is not overheating.

OPERATION & MAINTENANCE

If leakage is detected, it should be addressed as soon as possible to prevent hazards and protect personnel.
Leakage could come from a number of leak paths in the seal, or be caused by changes in the pump operation or
condition. Although seals should be inspected regularly for signs of leakage, a properly selected and functioning
mechanical seal will run for extended durations without need for extra attention and should not be disturbed
