Bonded (BR) Rubber Piston
The one-piece nitrile bonded piston is designed and manufactured to handle the tough environment encountered during land and offshore drilling. The oil resistant rubber provides optimal performance in oil water based muds.
Features:
-
High tensile strength.
-
Performs best in water-based mud.
-
Excellent chemical and abrasion resistance.
-
Maximum operating temperatures of up to 250°F.
-
Extended service life.
-
Available from 3” to 7-1/2”.
Replaceable (RR) Rubber Piston (Duplex & Triplex)
The Replaceable rubber pistons fully interchange with API standard piston hubs (SERIES A, B, K & L). Our piston rubbers are manufactured for a high grade of coated fabric and 80 Durometer XNBR rubber which provides a high degree of abrasion and oil resistance insuring longer life in most pumping applications.
Features:
-
High tensile strength.
-
Performs best in water-based mud.
-
Excellent chemical and abrasion resistance.
-
Maximum operating temperatures of up to 250°F.
-
Extended service life.
-
Available from 3” to 7-1/2"
Long Life Urethane Bonded Piston
Long Life Urethane Bonded Pistons are built to deliver superior performance in today’s Oil based and Synthetic drilling muds. Longer piston life equates to longer Liner life greatly reducing the cost associated with running your mud pumps and the time involved in replacing worn out fluid end expendables. Our urethane bonded pistons are manufactured from proprietary materials that expands against the Liner to create a tight seal as fluid pressure increases, reducing friction, thus reducing Liner wear.
Features:
-
For all drilling operations.
-
Maximum operating temperature of 230°F.
-
Designed to meet pressures of up to 5,000 psi.
-
Extended service life.
-
Available from 4” to 7"
Bullnose (BN) Urethane Bonded Piston
BN Pistons are designed to outlast all other polyurethane pistons on the market today. This rugged piston is engineered for high temperatures and demanding environments and will improve pump availability while reducing HSE risks.
Features:
-
For all drilling operations.
-
Enhanced piston running life.
-
Maximum operating temperature of 325°F.
-
Designed to meet pressures of up to 7,500 psi.
-
Extended service life.
-
Available from 4” to 7”.
HT Piston
HT Pistons are designed to perform in the harshest of drilling conditions and under all applications and mud types. HT pistons are manufactured from high performance urethane chemistry able to withstand operating temperatures up to 350°F and pressures of up to 7,500 psi.
Features:
-
For all drilling operations.
-
Maximum operating temperature of 350°F.
-
Designed to meet pressures of up to 7,500 psi.
-
Extended service life.
-
Proven, reliable performance in every piston.
-
Multi-durometer bonded urethane allows for longer piston life.
-
Available from 4” to 7”.
