Rubber Piston Cup

Smartly designed, the rubber piston cup is the main element for fluid end of mud pump. It is made of vulcanized rubber. To enhance the resistance to high temperature, nitrile rubber or polyurethane can be adopted as raw material for the production of mud pump piston cup.

As a professional supplier in the industry, we successfully develop the rubber piston cup with good resistance to abrasion and extended lifespan. The special technology helps the user improve the working efficiency of the mud pump.

Integrated Type Vulcanized Rubber Piston Cup
The integrated type vulcanized rubber piston cup is produced by vulcanizing the nitrile butadiene rubber or the PU to the made-up core, without troublesome fixation with pressing plate and circlip. Apart from high pressure jet drilling, this mud pump element can be used on ceramic cylinder sleeve.

White Rubber Piston Cup
The white rubber piston cup is made of synthetic rubber for the improvement in abrasion resistance and crushing resistance. It is suitable for the application in the environment with the liquid temperature of 220°F (104℃). The operating pressure of the rubber piston cup is up to 5000lb per square inch.

Green Rubber Piston Cup
With remarkable resistance to abrasion and high tensile strength, the green rubber piston cup limits the quantity of heat generated during extrusion, because of the integrated structure. The operating pressure can reach up to 6300lb per square inch.

Yellow Rubber Piston Cup
The rubber piston cup of this series can maintain its excellent performance in the liquid with the temperature up to 220°F. Reliably, the operating pressure reaches to 7500lb per square inch.

Black Rubber Piston Cup
The black rubber piston cup is manufactured with special processing technology. Installed with our product, the mud pump can afford the maximum rated pressure. Employing superior alloy steel as raw material, the rubber piston cup is processed with heat treatment technology for good sturdiness and durability. The operating pressure can be from 1500 to 2500lb per square inch.

Blue Rubber Piston Cup
Particularly suitable for the application in severe environment, the blue rubber piston cup has good resistance to abrasion and high tensile strength. The operating pressure is up to 7500lb per square inch.
