DL Vertical multistage booster water pump

DL vertical multistage centrifugal booster water is for vertical multistage multi section structure as the high efficient and energy saving pump.

The screw clamps the inlet section, middle section and outlet section into one. Each stage of the water pump is equipped with an impeller and a water guide vane. Shaft seal adopts soft packing or mechanical seal. The pump is manufactured according to JB/ t2727-93 standard for vertical multi-stage centrifugal pump. DL pump is used to handle the clean water, non-corrosive, non-explosive other liquids without solid particles or fibers. Other liquids are similar to water in physical and chemical properties.

Application:

DL type vertical multi-stage centrifugal pump is widely used in firefighting, domestic water supply, air conditioning unit circulation and cooling water transmission in high-rise buildings.

Features

1. Advanced hydraulic model: high efficiency, wide performance range.

2. Novel structure, reliable operation: the balancing drum is cancelled, and its axial force is balanced by hydraulic power, which completely solves the problems of easy corrosion, easy to bite and easy to wear of the balancing drum, and ensures more reliable operation.

3, less operation and maintenance costs: the use of high-quality mechanical seal, wear resistance, no leakage, long service life, low failure rate, with less operation and maintenance costs.

4, smooth operation, low noise: the use of low speed motor, so that the pump smooth operation, lower noise.

5. Vertical structure, small floor area.

Performance range:

flow: 4.2-504m3/h;

Head: 24-240 - m;

Power: 1.5 to 450 kw.

Speed: 1480 r/min.

Liquid temperature: normal temperature type -15℃ to +70℃ hot water type +70℃ to +120℃

Ambient temperature: maximum +40℃

Construction:

The basic structure of multistage centrifugal pump is composed of six parts: impeller, pump body, pump shaft, bearing, seal ring, packing box.
