Product details

3DP-80 high-pressure reciprocating pump

product overview

The 3DP-80 series high-pressure reciprocating pump is mainly suitable for use as a process pump in the petroleum, chemical, and fertilizer industries, as a water injection pump in oil fields and salt mines, as a pressure testing pump and booster pump for steel pipes and pressure vessels, as well as for high-pressure cleaning and descaling in industries such as construction, shipbuilding, and chemical engineering. It is also used as a transmission source for boiler feedwater and hydraulic machinery, as well as for departments such as food, pharmaceuticals, and instrumentation that require high-pressure fluids and high process pulse requirements.

Working structure principle

A high-pressure reciprocating pump is composed of an electric motor, a coupling, a reducer, a transmission part, a pump head part, a common base, etc. It is driven by an electric motor through a reducer, belt drive, or continuously variable speed controller to rotate the crankshaft, pushing the connecting rod through a slider (crosshead) to make the plunger move back and forth in a straight line, and achieving the purpose of suction and discharge under the opening and closing of the inlet valve of the pump head. The material of the high-pressure reciprocating pump head can be customized according to the needs of users for conveying various high-pressure liquids, using forged carbon steel alloys, stainless steel, etc. The main flow parts such as inlet and outlet valve seats, valve sleeves, valve disc packing boxes, plungers, etc. are made of 2Cr13, stainless steel, non-metallic materials, and the valve ball is made of 9Cr13, ceramic, F46 and other materials.

The high-pressure reciprocating pump produced by our company has advanced design and novel structure. The technical conditions of the pump comply with GB9234 "Technical Conditions for Mobile Reciprocating Pumps", and the test method of the pump complies with GB7784 "Test Method for Mobile Reciprocating Pumps". It has the characteristics of smooth operation, easy maintenance, safe and reliable sealing, long service life of vulnerable parts, and high volumetric efficiency of the pump.

(Pump body materials include alloy steel, martensitic, austenitic stainless steel, 316, 316L duplex steel.)
