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 14.

For overnight shutdown, stop the pump at the bottom of its stroke to prevent fluid from drying on the ex- posed displacement rod and damaging the throat packings. Relieve the pressure.

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