*Multi-stage centrifugal pump
D. Type vertical multi-stage centrifugal pump (referred to as: D. multi-stage pump) is a vertical single-suction multi-stage segmented centrifugal pump for transporting solid particles. It is used for clean water and liquids with physical and chemical properties similar to water. It is mainly used for water supply in high-rise buildings. It can also be used for water supply and drainage in factories and mines, and for transporting liquids. The flow rate range is .
D, type series multi-stage pumps are suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise buildings, fire pressurization, long-distance water supply, heating, bathrooms, boiler hot and cold water circulation pressurization, air conditioning and refrigeration system water supply and equipment supporting Wait for the occasion. The operating temperature of type D medium does not exceed ℃. The operating temperature of type medium shall not exceed ℃.

D. Multi-stage pump product features
The pump has compact structure, small size and beautiful appearance. Its vertical structure determines the installation space. The ground area is small, and its center of gravity coincides with the center of the pump feet, thereby enhancing the operating stability and service life of the pump.
The pump suction inlet and discharge outlet are both horizontal, simplifying pipeline connections.
The suction port and the discharge port can be installed in the same direction or in several different directions as needed to meet different connection situations.
The pump head can be increased or decreased according to the needs of the pump stage and combined with cutting the outer diameter of the impeller to meet the requirements without changing the installation area, which is not available in other pumps.
The pump with motor and rainproof cover can be placed outdoors for use, eliminating the need for a pump room to save construction costs.
The pump rotor has a small winding and the selected step motor has smooth operation, small vibration, low noise and long service life.
The rotation direction of the D-type vertical multi-stage centrifugal pump is counterclockwise when viewed downward from the driving end.
, D vertical multi-stage centrifugal pump has a compact structure, small volume, beautiful appearance, small footprint, and saves construction costs
, D vertical multi-stage centrifugal pump’s suction and outlet are on the same center line to simplify the piping The connection of the road
, according to the actual situation, the inlet and outlet of the D vertical multi-stage centrifugal pump can be assembled in different directions
, according to the actual situation, the outlet of the D type vertical multi-stage centrifugal pump can be assembled into ~ outlet to meet different requirements on the same pump.
The vertical multi-stage centrifugal pump is composed of a motor and a pump. The motor is a three-phase asynchronous motor. The pump and motor are connected by a coupling and the whole is rigidly connected. The pump is composed of a stator and a rotor. The stator part of the pump is composed of water inlet section, middle section, guide vane, water outlet section, stuffing box body and other components. In order to prevent the stator from wearing out, the stator is equipped with sealing rings, balance sleeves, etc. After wear, they can be replaced with spare parts. The rotor part consists of a shaft, a middle wheel, a balance drum, etc. The lower end of the rotor is a lubricated bearing and the upper part is an angular contact ball bearing. Most of the axial force of the pump is borne by the balance drum. The remaining small part of the axial force is borne by the angular contact ball bearing. The joint surfaces of the water inlet section, the middle section, and the water outlet section are sealed with paper pads by tightening them. The shaft seal adopts packing or mechanical seal, users can choose according to their needs. The direction of rotation of the pump is counterclockwise when viewed downward from the drive end.
