High pressure reciprocating pump is a new type of plunger pump designed and developed according to the requirements of high-pressure water injection technology in oil fields. Generally speaking, it belongs to the category of mobile reciprocating pumps. The hydraulic end of the high-pressure reciprocating pump adopts a horizontal straight through combination valve structure and applies splash lubrication. Its characteristic is that as long as the lubricating oil is within the specified range, it can ensure good lubrication of the bearing and crosshead on its own.

The suction and discharge valves of the high-pressure reciprocating pump are designed as a combination valve, with a compact overall valve group structure, easy processing, good sealing, easy replacement, and long service life. The pump head is made of 2Cr13 hot forged stainless steel, which can enhance mechanical strength and corrosion resistance, and will not cause pump head fracture, greatly extending the service life.

High pressure reciprocating pumps have the characteristics of high pump efficiency, stable and reliable operation, easy operation, wide range of pressure and displacement adjustment, and long service life of vulnerable parts; Suitable for transporting crude oil with a temperature not exceeding 80 ℃, a kinematic viscosity not exceeding 850 mm ²/s, a mechanical impurity content not exceeding 30mg/L, a solid particle size not exceeding 15 μ m, and a water content not exceeding 2%; Oilfield wastewater or clean water with a temperature not exceeding 80 ℃, a total mineralization degree not exceeding 30000mg/L, a mechanical impurity content not exceeding 30mg/L, and a solid particle size not exceeding 15 μ m.

High pressure reciprocating pumps can be used for oilfield water injection and well washing, and can be used as hydraulic piston pumps, surface pumps, thermal recovery boiler feed pumps, microbial solution injection pumps, and various types of equipment powered by hydraulic pressure. They are commonly used in modern industry as high-pressure hydraulic equipment, suitable for flushing, sand cleaning, rust removal, and liquid transportation. Widely used in mining, construction, cement, automotive and petrochemical industries, as well as transportation, municipal environmental protection and other fields.
