Replacing the dynamic seals and

plungers

Use this procedure if service is required outside of the
preventive maintenance schedule. It is important that
you continue to maintain the pump according to the
procedures specified in the required maintenance kit
instructions.

Remember, different horsepower pumps have different
maintenance intervals. See the interval listing on
Page 26, and refer to drawing 049656.

In the event of premature failure, you will need to inte-
grate dynamic seal repair with the preventive mainte-
nance described in this manual. FLOW suggests the
following strategy.

Premature failure close to the scheduled time

If the dynamic seal fails within 50 hours of a scheduled
service, perform a complete service procedure. Record
the actual hour meter reading when you install the main-
tenance kit—the next scheduled maintenance should
take place at the specified number of hours from this
reading.

For example, suppose you have a 50 hp pump. The Dy-
namic Seal maintenance interval is every 300 hours. The
dynamic seal fails at 250 hours, 50 hours short of a
scheduled maintenance period. Install the Dynamic Seal
maintenance kit, but the next scheduled maintenance
would take place at 550 hours, not 600 hours.

Premature failure midway between
scheduled service

If the dynamic seal fails somewhere midway between
two scheduled service periods (for example, a dynamic
seal on a 50 hp pump that fails at 150 hours since last
service), FLOW recommends replacing all components
to prevent unexpected down time.
