MAINTENANCE
Shutdown and Care of the Pump
Always follow the Pressure Relief Procedure Warning on page 7 whenever you shut of f the pump. Stop the pump at the bottom of its stroke to keep fluid from drying on the exposed displacement rod and damaging the throat packings.
Every 40 hours of operation, check that the packing nut/
Always flush the pump before the fluid dries in the pump and hoses. If the pump is to be stored for any period of time, and you are pumping

Corrosion Protection
WARNING
Water, or even moist air, can cause your pump to corrode. To help prevent corrosion, never leave the pump filled with water or air. After normal flushing, flush the pump again with mineral spirits or oil– based solvent, relieve pressure, and leave the min- eral spirits in the pump. Be sure to follow all steps
of the Pressure Relief Procedure W arning on
