Product Overview
DL type vertical multistage centrifugal pump is a hydraulic model of IS type pump, which is a highly efficient and energy-saving product recommended by the state. It is a vertical multistage multi segment structure. The screw clamps and connects the water inlet section, middle section and water outlet section into a whole. Each stage of the water pump is equipped with an impeller and a guide vane. The hydraulic balance method is used to solve the axial force, and the residual axial force is borne by the ball bearing and lubricated with grease. The shaft seal adopts soft packing or mechanical seal. The product complies with JB/T2727-93 Type and Basic Parameters of Vertical Multistage Centrifugal Pump. It is mainly used for suction and delivery of diluted, clean, non corrosive, non explosive clean water and liquid without solid particles or fibers with physical and chemical properties similar to water.
All products of our company are designed and optimized by computers. The company has strong technical force, rich production experience and perfect testing means, so as to ensure the stability and reliability of product quality.
Product features
1. Advanced hydraulic model: high efficiency, wide performance range.
2. New structure and reliable operation: the balance drum is canceled, and its axial force is hydraulically balanced, which completely solves the problems of rust, seizure and wear of the balance drum, and ensures more reliable operation.
3. Less operation and maintenance costs: high-quality mechanical seals are used, which are wear-resistant, leak free, long service life, low failure rate, and have less operation and maintenance costs.
4. Stable operation and low noise: low speed motor is used to make the pump run stably and have lower noise.
5. Vertical structure, small floor area.
Scope of application
It is widely used in fire protection and domestic water supply of high-rise buildings, as well as circulating and cooling water transmission of air conditioning units.
