Urethane “Bullnose” Piston

GPM International “Bullnose” Piston is designed to perform in the harshest of drilling conditions, with following features.
 

  • Designed for High Temperature and Pressure Service (325°F/ 7500psi)
  • Suitable for oil, synthetic or water based mud
  • excellent chemical and abrasion resistance in the most demanding well conditions
  • Enhanced piston running life with a proprietary blend of lubricating agents
  • Reduced operating costs in challenging operating environments

Duplex Rubber Replacable Piston

Replacement Piston Rubbers are made with tough and durable Buna N rubber for all pressures and are ideally suited for either oil-base or water-base mud. A special processing of the fabric provides an unusual waterproof bond of fabric to piston which assures longer life. These high tensile strength pistons will be rated for all drilling operations.

Urethane Bonded Piston (Green Duo)

Green Duo Urethane Bonded Piston is constructed of oil-resistant polyurethane bonded to a solid metal hub. As fluid pressure increases, the urethane surface of the piston expands against the liner to complete the seal, even in the enlarged diameter of a worn liner bore. The Green Duo Urethane Bonded Piston offers a longer service life than replacement rubber pistons

Urethane Bonded Piston (HighTemp.)

Designed to perform in the harshest of drilling conditions. It is compatible with all applications and mud types and will withstand operating temperature from 20F to 350F with pressures up to 7500 psi.

  • Proven, reliable performance in every piston
  • Resistance to high pressures, abrasion and heat and extrusion
  • Multi-durometer bonded urethane allows for longer piston life

Rubber Bonded Piston

Designed and manufactured to handle the tough assignments encountered during land and offshore drilling operations. A special processing of the fabric eliminates leakage points and resistance to abrasion.

  • Performs Best in the water-based mud
  •  Excellent Chemical and Abrasion Resistance
