Piston

RONGLE offers a full range of mud pump pistons for triplex and duplex pumps: PU pistons, NBR rubber pistons, HNBR rubber pistons

According to the structure, it is divided into modular and one-piece.(Item 28)

Use for HNBR and high pressure pump.

Material: NBR, HNBR, PU.

PU Pistons

RONGLE’s PU pistons are manufactured from a proven urethane compound that delivers excellent resistance to tear, abrasion and extrusion while maintaining high mechanical properties.

The bonded design provides this piston with the strength to handle drilling pressures to 7,500psi (51.7 MPa) and resists damage and fatigue during thousands of operating cycles.

The core of RONGLE’s piston is the proprietary polyurethane compound, which is stronger and more chemically resistant that others in this field.

Our standard bonded- polyurethane piston is suitable for operation up to Maximum operating temperature is 180 °F. These standard pistons can be operated at pressures up to 7,500 psi (51.7 MPa)

Features & Advantages

These pistons come complete with a hub O-ring and sleeve.

These pistons are the best choice for oil-based and synthetic drilling fluids.

These pistons are bonded to the hub for optimal strength and extrusion resistance.

NBR rubber pistons

RONGLE’s NBR rubber pistons is made with nitrile rubber to resist extrusion and abrasion. The two piece design allows for rubber replacement at lower operating pressures, while the robust construction makes it suitable for running at pressures up to 7500 PSI. In a very wide range of drilling conditions, the replaceable rubber piston can run in fluids from clear water up to heavy weight drilling mud.

These pistons are fully interchangeable with most other manufactures products.

Features & Advantages

Size range 3″ through 7-1/2”.

Extended service life.

Perform well in versatile environment.

High tensile strength.

Rated for all drilling operations.

Maximum operating temperature is 250°F.
