PISTON

We provide a wide variety of pistons for mud pump applications, including bonded, urethane, rubber, and replaceable rubber or urethane inserts.

• All bonded and replaceable pistons are available in popular sizes.

REPLACEABLE RUBBER PISTONS

KERUI replaceable pistons are made with nitrile rubber or polyurethane and the piston’s maximum pressure capability is due to this oil, water, and heat resistant material. These pistons are fully interchangeable with most other manufacturers.

KERUI pistons are highly resistant to extrusion wear under the highest pump pressures. Replaceable piston offers maximum resistance to bending and hoop stresses generated by cylinder loads and rod fits, a benefit of their premium forged alloy steel bodies. Rated for all drilling operations up to 5000psi. Available sizes range from 3” through 7 1/2” and series are A, B, K, and L

BONDED TRIPLEX URETHANE PISTONS

KERUI’s bonded urethane pistons is designed for resistance to extrusions and abrasions. And with water cooling it will provide optimum performance in oil base mud and high drilling pressures.
