The multistage centrifugal pump is a single shell, segmented, multistage centrifugal pump.

The suction and discharge ports are vertically upward.

The front section, the middle section and the rear section are connected into a whole with a wear bar. The static joint surface between each section is mainly sealed by the metal surface, and there is no O-type rubber ring as an auxiliary seal.

The suction section, middle section and discharge section of DG high-pressure pump adopt forgings.

The standard configuration of the multi-stage pump bearing is to use soft packing seal, cooling with cooling water, or a mechanical seal according to user requirements.
