Preservation Between Jobs
The internal fluid end components can oxidize and corrode after exposure to well service fluid, especially if the
well service fluid contained water, brine, or acids. If possible, remove the valve covers and use dry,
compressed air to blow out moisture from the fluid end. After removing the valve covers, generously mist the
inside with a suitable lubricating oil to displace moisture and create a protective film on the metallic
components. Wear proper protection when working with compressed air on the inside of the fluid end.
Covering all exposed discharge or suction openings will help in further preventing ingress of moisture to the
pump.
