Flush the Pump

To avoid fire and explosion, always ground the
equipment and the waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
NOTE: Pumps (AC) are tested with lightweight oil,
which is left in to protect the Pump parts. If the material
you are using may be contaminated by the oil, flush it
out with a compatible solvent before using the Pump
(AC).
Always flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary. Flush
with a fluid that is compatible with the material being
dispensed and the equipment wetted parts.
NOTE: Check with your material manufacturer or sup-
plier for recommended flushing fluids and flushing fre-
quency.
NOTICE
To prevent damage to the pump from rust, never
leave water or water-based fluid in a carbon steel
pump overnight. If you are pumping a water-based
fluid, flush with water first. Then flush with a rust
inhibitor, such as mineral spirits. Relieve pressure,
but leave the rust inhibitor in the pump to protect
parts from corrosion.
