DL vertical multistage centrifugal pump

times：

Model DL vertical multistage centrifugal pump is my company according to our country on high-rise building water supply and drainage and country fire authority GB6245-98 standards in the development of new products. It adopts high efficient energy-saving hydraulic model, it has the advantages of high efficiency, wide range of performance and other advantages, to better meet the requirements of users. In addition, the type of pump used in the structure of a vertical and segmental structure, and the advantages of security, stability, long life, small area, safety and convenient repair. DL vertical multistage centrifugal pump is adopted the national recommended the use of energy efficient products of type IS pump hydraulic model, for vertical multistage segmental type structure. Screw the water, middle water, clamping together. Each level with a pump impeller, a turbine guide vanes. Axial force by hydraulic balance method, residual axial force by the ball axle bearing, grease. The soft packing seal or mechanical seal. The implementation of product JB/T2727-93 " vertical multistage centrifugal pump-Types and basic parameters " standards, mainly for sending smoke dilution, clean, no corrosion, no explosion of water and physical and chemical properties similar to water without solid particles or liquid fiber.
The Division products using computer design and optimization of processing, the company has strong technical force, rich production experience and improve the detection means, to ensure product quality is stable and reliable.
Scope of application:
Widely used in high-rise building fire water supply and air conditioning units, life cycle, cooling water.
Vertical multistage centrifugal pump product features:
1, advanced hydraulic model: high efficiency, wide range of performance.
2, novel structure, reliable running : the abolition of the balancing drum, the axial force applied hydraulic balance, completely solve the balancing drum is easy to rust, easy to kill, the problem of easy abrasion, ensuring more reliable operation.
3, less operation, repair costs: high quality mechanical seal, wear resistance, no leakage, long service life, low failure rate, with fewer operating repair costs.
In 4, stable operation, low noise : the low speed motor, so the pump running smoothly, lower noise.
5, vertical structure, small occupied area.Technical parameters:
Flow rate: 4.2-504m3/h;
Head: 24-240m;
Power: 1.5-450kw;
Speed: 1480r/min;
Caliber:φ40- φ 250;
Temperature range: 0-+90℃;
Working pressure:≤ 2.4Mpa.
