How to Start a Pump
ALWAYS TAKE SPECIAL PRECAUTIONS WHEN STARTING A PUMP FOR THE
FIRST TIME OR AFTER ANY EXTENDED SHUTDOWN. NEVER ASSUME THAT
SOMEONE ELSE HAS PROPERLY PREPARED THE PUMP AND SYSTEM FOR
OPERATION. ALWAYS CHECK EACH COMPONENT OF THE SYSTEM PRIOR TO
EVERY START-UP.
The checklist that follows is intended to be a general guide for starting a pump in a typical
installation. Every installation is different, and each will have different requirements to insure
safe and successful operation. It is the responsibility of the operator to determine the correct
start-up procedure for each installation.
1. Insure that the drain plugs on the bottom of the pump crankcase have been installed and
are tight. Insure that the oil level sight glass has been properly installed.
2. Check the oil level to insure that the pump is properly filled and that the oil has not been
contaminated with water or other liquids. FMC pumps are not shipped with oil in the
power frame and must be filled with the proper grade of oil prior to start-up. The M28
pump requires 13 gallons (49.2 liters) of oil. Use the chart provided in Section 6 for
assistance in selecting the correct type of oil for your service.
3. Insure that the pressure relief valve and all accessory equipment have been installed and
properly adjusted. Verify that all joints are pressure tight.
4. Open the suction line valve to allow fluid to enter pump.
5. Check to insure that power is locked out, and then turn the pump over by hand if possible
to insure free, unobstructed operation.
6. Make sure that all guards are in place and secure. Verify that all personnel are in safe
positions and that system conditions are acceptable for operation.
7. Start the pump. Whenever possible, use a bypass line for the flow to allow the pump to
start in an unloaded condition (no discharge pressure). Slowly close the bypass line to
bring the pump into full load conditions. Shut down immediately if the flow becomes
unsteady, pressure fluctuates or if unusual sounds or vibrations are noted.
