1. Mud pump piston assembly
1).The function of the piston is working under high temperature, high pressure and bad lubrication conditions.
2).The pistons are fully interchangeable with other API standard designed pistons and deliver maximum performance in almost all drilling conditions. The hub is formed from 45# round steel. The piston rubber is made from specially formulated compounds which are resistant to the effects of heat, oil and water.
3).The multi-ply fabric reinforced backings used in the production of the pistonrubbers provide positive, wear resistant seals. High tensile strength, resistance to chemicals, hydrocarbic.
2. Specifications:
Outer diameter: 4 1/2" -- 7 1/2" Inner diameter: 1 1/2" --1 5/8"
Cup Material:
1) NBR working tempreture: 120°c , working life: 150-200 hours, quality guarantee: 1years
2) PU working tempreture: 60°c , workinglife: 200 --300 hours, max pressure: 25Mpa
3. Features:
1). Piston Assemblies are available both insingle and double acting type
2). They are available for different models ofpumps, such as EMSCO,Gardner Denver, IDECO,OILWELL,NATIONAL.
3). Piston rubber of piston assemblies aremanufactured by using very high strength polymer with very tough fabric backing.
4). Special care is taken for accuratedimensions of Piston body to ensure very long life .
5). Kingwell's piston assemblies give very longlife even under extreme working conditions.
