discharge line or between the pump and relief valve. FMC recommends that the
discharge be returned to the tank or drain, not back into the pump suction line.
5. It is recommended that a start-up bypass line and valve be installed to allow flow
to bypass the relief valve. This allows the pump to start in an unloaded condition
(no discharge pressure).
4.6 Multiple Pump Systems
Special consideration must be taken to avoid vibration, pulsation, or uneven flow
distribution problems when operating multiple reciprocating pumps using common
suction and discharge piping headers. It is recommended that the user contact FMC or
experienced industry consultants for assistance with the design of the system and pump
installation in these situations.
5.0 How to Start a Pump
CAUTION: 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 plug(s) on the bottom of the pump crankcase have been
installed and are tight. Insure that the oil level sight glass, if equipped, 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 contaminants. NOTE: 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.
NOTICE: The L16 model pump requires 80W90 non-detergent gear oil. For all other
pumps (L06 through L12) use Table 2 provided in Section 6.0 for selecting the correct
type of oil for your service.
