Vertical multistage centrifugal pump consists of two parts: motor and pump. The motor is a Y-type three-phase asynchronous motor. The pump and the motor are connected by a coupling. The whole is rigidly connected, and no correction is required during use. The pump consists of a stator part and a rotor part. The pump stator part is composed of water inlet section, middle section, guide vane, water outlet section, stuffing box and other parts. In order to prevent stator wear, the stator is equipped with sealing ring, balance sleeve, etc., which can be replaced with spare parts after wear. The rotor part consists of shaft, impeller, balance hub, etc. The lower end of the rotor is a water-lubricated bearing, and the upper part is an angular contact ball bearing. Most of the axial force of the vertical multistage centrifugal pump is borne by the balance drum, and the remaining small part of the residual axial force is borne by the angular contact ball bearing. The water inlet section, the water outlet section and the joint surface are sealed with paper pads through jointing. The shaft seal adopts packing or mechanical seal, users can choose according to their needs.

Vertical multistage centrifugal pump The rotation direction of the vertical multistage centrifugal pump is counterclockwise when viewed from the driving end.
1. The vertical multistage centrifugal pump has compact structure, small volume, beautiful appearance, small footprint, and saves construction costs;
2. The suction port and the water outlet of the vertical multistage centrifugal pump are on the same center line, which simplifies the connection of the pipeline;
3. According to the actual situation, the inlet and outlet of the vertical multistage centrifugal pump can be assembled in different directions of 90°, 180°, and 270°;
4. According to the actual situation, the outlet of the vertical multistage centrifugal pump can be assembled into 1 to 5 outlets, so as to obtain different heads on the same pump.
