10.0 Service Procedures
FMC pumps are designed to simplify all required maintenance. The following sections
illustrate step-by-step instructions for performing most common service procedures of a
pump. Read each section before starting service work on the pump.
Refer to Figure 2, Figure 3, and Figure 4 for location of components.
It is recommended that a sufficient quantity of clean water be pumped through the fluid
end before starting any service procedures that involve fluid end components. This will
remove a significant portion of contaminants left in the fluid cylinder by the normal
pumpage and improve the ability to work with parts or see potential problems.
WARNING
Many accidents occur every year through careless use or service of
mechanical equipment. You can avoid hazards associated with high-
pressure equipment by always following the safety precautions listed in
Section 1.0.
10.1
Replacing Plunger Packing
CAUTION
CHECK TO ENSURE THAT THE POWER IS LOCKED OUT AND TAGGED
OUT (MOTOR OR ENGINE CANNOT BE STARTED).
1. Bleed off all pressure inside pump fluid end before starting
any service work. Shut the valve on the inlet piping, if
provided, to prevent flow of liquid from the source into the
pump during service work.
