DL vertical multistage centrifugal pump

1. Product overview of DL vertical multistage centrifugal pump:

DL type vertical multi-stage centrifugal pump is a hydraulic model of IS type pump, which is a high-efficiency and energy-saving product recommended by the state. It is a vertical multi-stage and multi-segment structure. The screw clamps the water inlet section, the middle section and the water outlet section into one. Each stage of the pump is equipped with an impeller and a guide vane. The axial force is solved by the hydraulic balance method, 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 implements the JB/T2727-93 "Vertical Multistage Centrifugal Pump Type and Basic Parameters" standard, and is mainly used for suction and transportation of diluted, clean, non-corrosive, non-explosive clean water and non-solid particles with similar physical and chemical properties to water. or fibrous liquid. All products of our company are designed and optimized by computer. The company has strong technical force, rich production experience and perfect testing methods, so as to ensure stable and reliable product quality.

2. DL type vertical multistage centrifugal pump application scope:

Widely used in high-rise buildings for fire protection, domestic water supply and air-conditioning unit circulation, cooling water delivery.

3. Features of DL vertical multistage centrifugal pump:

1. Advanced hydraulic model: high efficiency and wide performance range.
2. Novel structure and reliable operation: the balance drum is cancelled, and its axial force is hydraulically balanced, which completely solves the problems that the balance drum is easy to rust, bites and wears, and ensures more reliable operation.
3. Less operation and maintenance costs: high-quality mechanical seals are used, which are wear-resistant, leak-free, long in service life, low in failure rate, and have less operation and maintenance costs.
4. Smooth operation and low noise: The low-speed motor is used to make the pump run smoothly and with lower noise.
5. Vertical structure, small footprint.
