Valve PU Rubber is worked for oil drilling mud pump and cementing piston. It’s usage is sealing and buffer.
It is made of polyurethane material, which have the super advantage of oil resistant, corrosion resistance, abrasion resistance. And wild work temperature of -35ºC-100ºC, work pressure of 40MPa. Polyurethane have long lifetime than rubber, it’s wildly used for the consumables of oilfield fracturing cars, oilfield washing cars, cementing cement truck cement truck, piston pumps, mud pumps and other oil equipment.
1.The rubber products are application to both oil base and water base drilling mud.
Including: seals, piston rubber, valve insert, bladder, etc.
2.The piston rubber and valve rubber are the mainly spare part of mud pump fluid end system,
in the meantime, it is one of the use of the largest wearing parts.
3.The piston rubber, valve rubber is the vulcanization of rubber products .
The material of ordinary piston rubber is nitrile rubber , acrylate rubber .
| Piston Type | Temperature Range | Pump Pressure | Abrasion Resistance | Drilling Fluid |
| Piston With Replacement Rubber | -30~100 °C -22~210 °F | 5000PSI(35Mpa) | Not Bad | Water base |
| Piston With Replacement Urethane Rubber | -40~85°C -40~185 °F | 5000PSI(35Mpa) | Excellent | Water base & Oil base |
| Piston With Replacement High Temperature Rubber | -50~150 -58~300 °F | 7500PSI(52Mpa) | Good | Water base & Oil base |
| Bonded Urethane Piston | -40~85 °C -40~185 °F | 5000PSI(35Mpa) | Excellent | Water base & Oil base |
| Bonded High Temperature Piston | -50~150 °C -58~300 °F | 7500PSI(52Mpa) | Good | Water base & Oil base |
