HW200HF-S high pressure pump is a new medium and low pressure large flow pump developed by our company with a maximum working pressure of 70MPa. The maximum input power of the power end is 200kw. The liquid end uses finite element analysis method to optimize the structure to ensure stable and reliable continuous operation. The integral pump head optimizes the pressure chamber structure. The pump type can meet the working pressure of 40-70MPa and the continuous operation of flow rate 120-250L/min. It can be used for large diameter pipe cleaning, powder metallurgy, chemical industry reactor tank cleaning and descaling, large pipeline water injection and pressure test. This series of products can deliver 0-50℃of clear water, emulsion and chemical liquids similar to clear water.
