HW250D-S series high pressure plunger pump is a new generation high pressure plunger pump independently developed by our company.The pressure can reach 165 MPa. Technical features: 1.Straight-through hydraulic end, advanced technology,reasonable design, higher volumetric efficiency. 2.The high seal adopts the new polymer material. 3.Cemented carbide plungers are durable. 4.Easy Maintenance, one person can complete the hydraulic end maintenance and replacement of wearing parts. 5.The hydraulic end parts are made of precipitated hardened martensitic stainless steel, which are reliable and durable. 6.The dynamic end is designed by finite element method, which optimizes the structure and improves the reliability of the lubrication system. 7. This product is matched with the new diaphragm type safety valve (original imported diaphragm),easy to operate, safe and reliable. This series of products can transport 0 ~ 50? water, emulsion, and other chemical property similar to water liquids. This series of high pressure pumps are widely used in jet cleaning, power, powder metallurgy and other industries.
