Flush
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
lower possible pressure.
Flush the Pump:
•
Before first use
•
When changing 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.
