Flush the Pump

To avoid fire and explosion, always ground the equip-
ment and the waste container. To avoid static spark-
ing and injury from splashing, always flush at the
lowest possible pressure.
NOTE: The pump is tested with lightweight oil, which is
left in to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a com-
patible solvent before using the pump.
Always flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary. Flush
with a fluid that is compatible with the fluid being dis-
pensed and the equipment wetted parts.
NOTE: Check with your fluid manufacturer or supplier
for recommended flushing fluids and flushing frequency.
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.
NOTE: Refer to the E-Flo SP Software Instructions
manual for additional information about using the
software features of the ADM. See Related Manuals on
