The flange design is executed in accordance with ASME B16.5 600#，and the pump body support feet are strengthened to meet the pipe load requirements specified in API 610. At the same time, efficient hydraulic flow design is adopted to significantly reduce energy consumption and demonstrate excellent performance. The shaft system design adopts a heavy position to ensure that the seal deflection fully meets the design specifications of API 610. Reliable heavy-duty bearing unit design that performs well under high pressure conditions. A standard oil ring is provided, and an efficient channel lubrication passage is equipped to ensure the stability of the bearing operation. The high standardization design not only reduces inventory costs but also achieves the maximum interchangeability of components, thereby reducing the operating costs of the equipment throughout its life cycle.
