Operation

Shutdown and Care of the Pump

For overnight shutdown, stop the pump at the bottom of the 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. Refer to Flushing below.
