HW250E-S series high-pressure piston pump is based on HW250D power endAnd match a variety of transmission speed ratio, independent research and development of a new hydraulic end, the maximum pressure of up to 270MPa a new generation of high-pressure plunger pump products.
Technical features: 1. Straight-through hydraulic end, advanced technology, reasonable design, higher volumetric efficiency. 2. Polymer sealing material, self-adjusting preload with pressure, sealing automatic compensation. 3. Carbide plunger is strong and durable. 4. Easy maintenance: one person can complete the maintenance of the hydraulic end and replace the wearing parts. 5. The hydraulic end parts are made of precipitation hardened martensitic stainless steel, which is reliable and durable. 6. This product matches the new diaphragm type safety valve (original imported diaphragm) with simple operation, safe and reliable.
This series of products can transport 0~50 °C water, emulsion and other liquids with chemical properties similar to water. This series of high-pressure pumps are widely used in jet cleaning, electric power, powder metallurgy and other industries.
