Premium Pistons are made to precise tolerances and include a variety of materials yielding extended service life. Piston materials include the following from 3” to 7-1/2” sizes to accommodate for all types of drilling conditions, mud properties and temperatures reaching up to 350°F.
Premium provides a full range of mud pump pistons for both triplex and duplex pumps. They are:
Replaceable Rubber Piston
Long Life Urethane Bonded Piston
High Temperature Bonded Piston
BullNose Piston
FlexLip Piston
Features:
Rated for all drilling operations
High tensile strength
Maximum operating temperature is 350°F
High pressure mud pump service
Extended service life
Urethane Bonded Piston
These pistons are constructed of urethane, bonded to a solid metal hub. Double durometer urethane is designed to provide optimum performance in oil base or water base mud and high drilling pressures.
Features:
- Rated for all drilling operations
- Maximum operating temperature is 180°F
- High pressure mud pump service
Southwest’s Dual-Duro® piston has provided unmatched performance in extreme drilling conditions since 1985.
Made of Dual-Durometer Polyurethane, this triplex pump piston is designed to resist extrusion which ultimately extends the life of the piston. Drilling operators worldwide trust the superior performance and unmatched durability of the Dual-Duro® piston.
Key Features Include:
ü Excellent liner wear characteristics
ü Maximum working temperature up to 180°F
ü High resistance to chemical breakdown, tearing and abrasion
ü Recommended for use in oil-based drilling mud but can also be used in water-based
