5. Never allow a pump to run dry of the fluid being
pumped. A dry pump quickly speeds up and can
damage itself. If it speeds up, shut off the power
supply to the reciprocator immediately. Refill the
supply container and prime the pump to eliminate
air.
NOTE: To prevent the pump from running dry, use a
low-level cutoff valve.
Shutdown and Care
At the end of the work shift or when the pump is unat-
tended, always relieve the pressure, see Pressure Relief
Procedure on page 8.
Emergency Stop Procedure
Close the supply line shutoff valve marked STOP.
