The information given here is an estimate of the average wear life of listed components
in clean liquid service. It is not a guarantee of life for any given application, but is
intended to facilitate maintenance schedules and stocking of spares. The maintenance
of the power end lubrication system will influence the life of the power end components.
The speed of operation and percent of maximum allowable load will influence the life of
both power end and fluid end parts. The temperature, abrasiveness, and lubricity of the
liquid affect the life of fluid end expendables.
