It includes modules, liners, extension rods, piston rods, pistons , threaded rings, caps, valve covers, valve guides, valves, seats etc. for all major brands of pumps: Gardner Denver®, Ideco®, Emsco®, National®, Oilwell®, Skytop Brewster®, Lanshi(3NB1300C) ®, Bomco ®, HH ®.

BOPM offers a complete line of interchangeable fluid end modules and accessories for triplex mud pumps, such as National, Emsco, Gardner Denver, Bomco, Ideco and Oilwell. We offer both standard OEM style replacement parts and Two piece “L” Shaped fluid ends.

Our high-strength, triple reduction, forged steel triplex fluid end modules are made from highest alloy steel. Heat treated for long working life, they are machined to perfection and packaged for delivery with anticorrosion protection. The precisely made jewelry-like exterior finish reflects our superior quality.

BOPM piston rods are made with premium grade, heat treated alloy steel. The rods offer excellent resistance to fatigue, corrosion and heavy loads. A full line of piston rods are available for various pumps.

BOPM extension rods are made from high strength alloy steel, and are either heat treated or chrome plated. The rod offers excellent resistance to fatigue, corrosion and heavy loads. BOPM extension rods are machined and polished to ensure a perfect seal to protect the mud pump gear end.

All of our gear set adopt high-end carburization heat treatment and precise grinding machining to offer unparalleled durability; first we use high strength alloy steel, then adopt the Carburization heat treatment to enhance the hardness and wearability, finally adopt the grinding fine machining to ensure the smooth gear teeth surface; Resulting in consistent and rugged performance throughout pump operation.

BOPM bonded urethane pistonsare constructed of urethane, bonded to a steel hub. The double durometer urethane is designed to provide optimal performance in oil or water based mud and high drilling pressures.

BOPM Replaceable Rubber Pistonis made with tough and durable Buna N rubber for all pressures, and is ideally suited for water-base mud. A special processing of the fabric provides an unusually waterproof bond of fabric to piston which assures longer life.
