Fluid End Packages

Often imitated but never duplicated, Southwest Oilfield Products’ two-piece L-shaped fluid-ends have become the recognized standard.

The L-shaped two-piece fluid-end was adopted into the market over 50 years ago because it was an obvious improvement over one-piece modules. Since the suction module is separate from the discharge module, it is possible to replace the suction module when it wears out instead of replacing the entire fluid end.

Changing valves or seats on a two-piece module is also much easier, safer, and faster than changing valves or seats on a one-piece module.

Southwest’s L-shaped fluid-end is manufactured from heat-treated 4130 forgings and equipped with our quick-change valve cover system; our L-shaped modules offer unmatched performance.

Southwest’s second to none manufacturing is backed by the best warranty on the market.

Our 7,500 PSI fluid-end upgrade replaces outdated 5,000 PSI systems with our proven two-piece L-shaped module. This upgrade includes an advanced liner retainer system, high-pressure discharge options, and a durable 7500 PSI pulsation dampener. Ideal for drillers who prioritize efficiency, safety, and cost-effectiveness, our fluid-end upgrade enhances operational resilience with seamless integration into existing pump systems across various makes and models.

Available 7500 P.S.I. Models include:

• BOMCO® F1600
