Operation

Shutdown and Care of the Pump

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 9.

For overnight shutdown, relieve the pressure. Always stop the pump at the bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and damaging the throat packings.

Always flush the pump before the fluid dries on the displacement rod. See Flushing below.

Flushing

WARNING

FIRE AND EXPLOSION HAZARD

Before flushing, read the section FIRE

AND EXPLOSION HAZARD on page

4.Be sure the entire system and flush- ing pails are properly grounded. Refer to Grounding on page 5.

Flush the pump:

DBefore the first use

DWhen changing colors or fluids

DBefore fluid can dry or settle out in a dormant pump (check the pot life of catalyzed fluids)

DBefore storing the pump.

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.

If the pump is being used to supply a circulating sys- tem, allow the solvent to circulate until the pump is thoroughly flushed.

CAUTION

Never leave water or water-base fluid in the pump overnight. If you are pumping water-base fluid, flush with water first, then with a rust inhibitor such as mineral spirits. Relieve the pressure, but leave the rust inhibitor in the pump to protect the parts from corrosion.
