According to the energy consumption status and characteristics of high pressure pump in Seawater Reverse Osmosis desalination unit of 2500m3/d and 5000 m3/d capacity, reasonable types of high pressure pump were chosen. Research on improving the efficiency of the two types of high pressure pump was made. Without affecting the pump reliability, structural optimization was made centering a round improving the energy efficiency or making efforts to improve energy efficiency. CFD technology was adopted in the fluid end design of the reciprocating pump and high efficiency hydraulic model chosen of the multistage centrifugal pump. For multistage centrifugal pump, several hydraulic models with good hydraulic characteristics were chosen. Numerical method was used in the performance prediction and modeling. Test results show that the optimized reciprocating pump efficiency reaches 93.36% and the multistage centrifugal pump efficiency reaches 80%. This research provides theoretical guidance for reducing energy consumption of Seawater Reverse Osmosis (SWRO) and improving the efficiency of high pressure pumps.
