DL/DLR multistage hot water pump designs as vertical multi-stage multi-stage structure by adopting the hydraulic model of IS pump, which is a nationally recommended high-efficiency and energy-saving product. It can treat clear water without solid particles and liquids with physicochemical properties similar to water in the fields of water supply for high-rise buildings, water supply and drainage for factories and mines, long-distance water supply and industrial water supply. Further, it adopts energy efficient hydraulic model, stable operation, high conveying efficiency and low running cost.
Product Details:
DLR series centrifugal pumps are vertical single suction multi-stage segmented centrifugal pumps. When the motor drives the pump shaft to rotate, the impeller on the pump shaft rotates with it. The rotation of the impeller causes the liquid to generate a low-pressure area in the centre of the impeller and a high-pressure area in the periphery of the impeller. Because of the pressure difference, the liquid is sucked into the centre of the impeller and thrown to the periphery of the impeller under the action of centrifugal force, so as to achieve the transmission of liquid.
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. 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.
Feature:
1. This machine suction and discharge ports are both horizontal, which simplifies the connection of pipelines.
2. Its motor is equipped with a rain cover, and the pump can be used outdoors, eliminating the pump room and saving construction costs.
3. The rotor of the this pump has a small deflection, and the 4-pole motor is selected, so it runs smoothly, with low vibration, low noise and long service life.
4. 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.
5. The head of the DLR booster water 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.
6. DLR vertical multi-stage pump adopts a vertical structure, which determines a small installation area and the centre of gravity coincides with the centre of the pump foot, thus improving the operational stability and service life of the pump.
