4.2
Maintenance Space Requirements
When determining the design of the pump installation, consideration must be given to the access needs for
general maintenance of the pump. Working space is needed to replace consumables such as valves, fluid end
plungers, and packing. Space is also needed to inspect and adjust the pinion bearing pre-load of the gear
reducer (see
Section 10.2
). Consideration should also be given to major repairs that must be accomplished at
the factory, and the pump package should be designed to allow for removal of the pump.
MSI has provided a combination weather cover and safety guard for the plunger access ports. The cover
additionally serves to store tools specific to the MSI Hybrid™ Well Service Pump. It is the responsibility of the
packager to design the unit in such a way that this equipment is intact and functional.
