Preventive Maintenance
Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
Tighten Threaded Connections
Before each use, check all hoses for wear or damage.
Replace as necessary. Check that all threaded connec-
tions are tight and leak-free.
Flushing
Flush the pump:
•
Before first use
•
When changing colors or fluids
•
Before repairing equipment
•
Before fluid dries or settles out in a dormant pump
(check the pot life of catalyzed fluids)
•
At the end of the day
•
Before storing the pump.
Flush at the lowest pressure possible. Flush with a fluid
that is compatible with the fluid you are pumping and
with the wetted parts in your system. Check with your
fluid manufacturer or supplier for recommended flushing
fluids and flushing frequency.
