5.0  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 ensure safe and successful operation. It is the responsibility of the 
operator to determine the correct start-up procedure for each installation. 
1.  Ensure that the drain plug(s) on the bottom of the pump crankcase have been 
installed and are tight. Ensure that the oil level sight glass, if equipped, has been 
properly installed. 
2.  Check the oil level to ensure that the pump is properly filled with non-detergent 
motor oil or a synthetic oil as described in Table 2 and that the oil has not been 
contaminated with water or other contaminants. 
FMC pumps are shipped with no oil in the power frame and must be filled 
to the proper level with the proper grade of oil prior to start-up. 
 
W11 pumps require 6 1/4 quarts (5.9 liters) of oil 
 
Consult Table 2 in Section 6.0 for selecting the correct type of non-
detergent motor oil or synthetic oil for your service. 
3.  If accessible, check the piston rods to ensure that they are free from abrasive 
particles or debris.  
4.  Ensure that the pressure relief valve and all accessory equipment have been 
installed and properly adjusted. Verify that all joints are pressure tight.
