HNA offers Pony Rods, Piston Rods and Clamps to meet today's tough oilfield requirements.

 Pony Rods

Our Pony Rods incorporate the longer wearing surface to provide the best Pony Rod for your Triplex or Duplex pump.

Piston Rods for Triplex Mud Pumps

The piston rods are manufactured to exacting standards to meet today’s tough oilfield requirements, available for a wide range of triplex mud pumps.
Our piston rods are manufactured from high quality alloy steel. Surface is induction hardened for maximum case hardness and core strength - hard on the outside, tough on the inside. Precision ground mirror surfaces meet rigid quality control standards and minimize wear.

Piston Rods for Duplex Mud Pumps

High quality Grayloy material is used on all HNA Duplex Piston Rods. This corrosion-resistant, high-density, long-wearing surface results in fewer packing changes and longer life for gland bushings and junk rings. HNA rods are furnished with a heavy duty Piston Lock Nut.

Clamps

HNA offers a full range of clamps for mating the piston rod to the crosshead extension (pony) rod. Machining tolerances are tightly held to assure proper fit and alignment of the adjoining components. HNA clamps are furnished complete with all required hardware.
