DL/DLR vertical multistage water pumps can be applied to convey clear water and liquids with physico-chemical properties similar to water, including domestic water for high-rise buildings, factory and mine drainage, long-distance water delivery, and water for various production processes. The pump adopts high-quality mechanical seal, so there is no leakage, wear-resistant and low failure rate in operation.
Product Details:
DL/DLR vertical multi-stage water pump adopts the hydraulic model of IS pump, which is a national recommended energy efficient product, and is a vertical multi-stage multi-section structure. When the motor drives the pump shaft to rotate, the impeller on the pump shaft also rotates. During the rotation of the impeller, the blades do work on the liquid, so that the liquid obtains energy, thus increasing the kinetic energy and pressure energy of the liquid. Due to the centrifugal force, the liquid is thrown from the center of the impeller to the edge of the impeller, forming a low-pressure area, while the center of the impeller forms a high-pressure area.
Application:
1. It is mainly used for high-rise building domestic water supply, fire constant pressure water supply, automatic spray water, automatic water curtain water supply, etc. It can also be used for water supply and drainage in factories and mines, long-distance water supply, supporting use of various equipment and water for various production processes.
2. The medium temperature of the DL vertical multistage centrifugal pump does not exceed 80℃, and the medium temperature of the DLR multistage centrifugal pump does not exceed 120℃.
3. It is used to transport diluted, clean, non-corrosive, non-explosive water and liquid without solid particles or fibers with physical and chemical properties similar to water.
Advantage:
1. DL/DLR vertical multi-stage pump has compact structure, small size and beautiful appearance. Its vertical structure determines the installation area is small, and its center of gravity coincides with the center of the pump foot, thus enhancing the pump's operational stability and service life.
2. The head of this pump can be increased or decreased according to the needs and combined with the outer diameter of the cutting impeller to meet the requirements, without changing the installation area, which is not available in other pumps.
3. According to needs, the suction port and the discharge port can be installed in the same direction or in different directions of 90°, 180°, 270° to meet different connection occasions.
4. The rotor of the this machine has a small deflection, and the 4-pole motor is selected, so it runs smoothly, with low vibration, low noise and long service life.
5. It is equipped with a rain cover, and the pump can be used outdoors, eliminating the pump room and saving construction costs.
6. Its suction and discharge ports are both horizontal, which simplifies the connection of pipelines.
