Many formations are too tight to produce oil and natural gas, and require a stimulation process to extract the resources. In hydraulic fracturing, fluids carrying proppant are pumped into the ground with enough pressure to crack the rock. The proppant is left behind to hold open the cracks, while the fluid is flowed back allowing oil and gas the ability to flow to surface. Fracturing pump seal pla...

Fracturing pump seals，also known as plunger pump packing or plunger packing seal, are mainly applied in fracturing trucks, mud pumps and cementing trucks for oil industry of harsh working conditions. The fracturing pump seals are combined with Top Adapter, Bottom Adapter and Pressure Rings. The number of the pressure rings is flexible, which allows the seal sealing at a wide range of pressures und...

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals. Its main function is to prevent plungers from leakage in high-speed reciprocating. Some special working conditions are taken into consideration when designing its structure and material, which make it apply to fracturing fluid, mud so on mediums. Technical Requirements...
