Routine Maintenance Procedures

4.5

4.5.1 Venting Pressure in the Fluid End

Before any maintenance is performed on the fluid modules, liners, pistons or valves, all
pressure should be vented from the system. To do so, close the shut-off valves in both the
suction and discharge lines and then open the optional by-pass line to rig the mud tanks.
Allow all pressure to vent before performing maintenance on fluid end components.
Even while at rest, the fluid end of the system is under significant
pressure, which if accidentally or inappropriately released can cause
significant equipment damage and injury to nearby personnel.
CAUTION
pressure must be vented from the system before any maintenance on
the fluid end is performed (see 4.5.1: Venting Pressure in the Fluid End,
above).

4.5.2 Pre-Installation Procedure

Before installing any parts or components into the system, all parts should be gathered
and checked to ensure they are ready for use before installation begins. This includes
checking that all mountings, sealing faces and bores are clean and free of burrs, nicks and
debris.
