DL Cast Iron Multistage Booster For High Buliding is a new product developed by our company according to China's high-rise building water supply and drainage and GB6245-98 standard of the National Fire Protection Bureau. This type of pump is highly efficient because it adopts an excellent hydraulic model with high efficiency and energy saving. The performance range is wide, which better meets the user's requirements. In addition, the pump adopts vertical and segmented structure, and the operation is safe, stable, long life, small floor space, convenient for safe maintenance. The DL vertical multistage centrifugal pump is a hydraulic model of the IS-type pump that is recommended by the state for energy-efficient products. It is a vertical multi-stage multi-segment structure. The screw clamps the inlet section, the middle section and the outlet section into one body. Each stage of the pump is equipped with an impeller and a water guide vane. The axial force is solved by the hydraulic balance method, and the residual axial force is received by the ball bearing and lubricated with grease. The shaft seal is made of soft packing or mechanical seal. The product implements JB/T2727-93 "Vertical multistage centrifugal pump type and basic parameters" standard, mainly for sucking diluted, clean, non-corrosive, non-explosive clean water and physicochemical properties similar to water without solid particles Or a liquid of fiber. The company's products are all designed and optimized by computer. The company has strong technical strength, rich production experience and perfect testing methods to ensure the stability and reliability of product quality.
● Advanced hydraulic model: high efficiency and wide performance range. ● The structure is novel and the operation is reliable: the balance drum is eliminated, and the axial force adopts hydraulic balance, which completely solves the problem that the balance drum is easy to rust, easy to bite and easy to wear, and the operation is more reliable. ● less operation, maintenance costs: the use of high-quality mechanical seals, wear-resistant, no leakage, long service life, low failure rate, with less operating and maintenance costs. ● Smooth operation and low noise: The low-speed motor is used to make the pump run smoothly and the noise is lower. ● Vertical structure, small footprint.
Conditions of Use
● The medium used should be similar to water, with a kinematic viscosity <150mm2/s, and no hard particles, no corrosive properties; ● The altitude of the DL vertical multistage centrifugal pump is <1000 meters. When it exceeds the time, it should be put in order, so that the factory can provide you with more reliable products; ● The medium use temperature -15 ° C ~ 120 ° C; ● The working pressure of the large system is ≤2.5MPa; ● The ambient temperature should be lower than 40 °C and the relative humidity should be lower than 95%.
DL vertical multistage centrifugal pump is mainly used for high-rise building life water supply, fire-fighting constant pressure water supply, automatic spray water, automatic water curtain water supply, etc. It can also be used for water supply and drainage of factories and mines, long-distance water supply, and various equipments. Various production process waters, etc. The medium temperature of the DL vertical multistage centrifugal pump does not exceed 80 °C, and the medium temperature of the DLR vertical multistage centrifugal pump does not exceed 120 °C.
