Shut down the pump
WARNING:
The pump can handle hazardous and toxic fluids. Identify the contents of the pump and observe proper
decontamination procedures in order to eliminate the possible exposure to any hazardous or toxic fluids.
Wear the proper personal protective equipment. Potential hazards include, but are not limited to, high
temperature, flammable, acidic, caustic, explosive, and other risks. You must handle and dispose of
pumped fluid in compliance with the applicable environmental regulations.
1. Slowly close the discharge valve.
2. Shut down and lock the driver to prevent accidental rotation.
3. If the driver is not equipped with a non-reverse ratchet (NRR), be certain that the unit is completely
stopped before you restart the pump.
Lubricate the thrust pot during a shutdown period
1. Completely immerse the bearings in oil.
This helps to avoid oxidation of the anti-friction bearings during shutdown periods lasting longer than
one week.
2. Fill the oil reservoir until the oil runs over the oil retainer tube and down the shaft.
Before startup, drain the oil to its required level.
