Multistage Water Pump

Milestone is a professional manufacturer of multistage water pump. The serial pump is multi-stage section centrifugal pump, the excellent hydraulic models are high-efficiency, energy-saving, and have wide performance range, operating safety & steady, low noise, long life and installing& repairing is very convenient etc. It can deliver heat water, oil, corrosive or wearable medium by changing the material, seal or adding cooling system.

 D, MD multi-stage mine pump adopts high-efficiency and energy-saving hydraulic model. The pump is mostly made of QT and other wear-resistant  materials, which are used to transport neutral mine water with solid particles ≤ 0.5mm. Content ≤ 10%, temperature ≤ 80°C and similar other media.

 D, MD multi-stage mining pump adopts high-quality balance disc ring system to balance the axial force. Because the pump adopts wear-resistant  materials, the service life of the pump body is ≧ 10 years, and the normal life of rotor components such as impellers is ≧ 5000 hours. At present, the  company produces this type of water pump with a flow rate of ≦1200m3/h and a lift of ≦1500m.

DG multi-stage high-temperature boiler feed water pump is a horizontal multi-stage segmental structure, which can transport clean water or liquids with physical and chemical properties similar to clean water. It is suitable for high, medium and low pressure boiler feed water. The temperature of the conveying medium is less than or equal to 170℃, and the allowable pressure at the inlet is less than or equal to 0.6Mpa.

The DG high temperature boiler feed pump is produced by the company's optimized hydraulic model, fully considering the high temperature environment, the pump uses a special material balance system to balance the axial force, the normal life of the rotor parts is ≥ 6000 hours, the pump body is made of alloy casting (forging), and the service life is ≥ For 10 years, our company currently produces this series of pumps with a flow rate of ≤500m3/h and an outlet pressure of ≤150kg/cm3.

 Applications

 Boiler feed water

 Pressure Vessel Water Supply

 Hot water circulation

 Fire pressurization

 Paper industry

 Chemical smelting

 Materials

 DG centrifugal pump is mainly composed of inlet and outlet sections, middle section, guide vanes, impellers, shafts, bushings, bearings, bearing bodies, seals,  etc.

 According to the difference of pump pressure and medium temperature, the pump flow parts are made of cast iron, ductile iron or cast steel, etc., and stainless  steel materials can also be used according to customer requirements.

ZPD self-balancing mining pump is a new generation of mining multi-stage pump independently researched and produced by our company. The pump mostly uses wear-resistant materials such as ductile iron, and is suitable for conveying neutral mine water and other similar media with solid particles ≤0.5mm, content ≤15%, and temperature ≤80°C.

The ZPD self-balancing pump adopts the front and rear balance structure of pump water pressure to balance the axial force of the rotor, which overcomes the problems of easy damage and difficult maintenance of the balance system, and greatly improves the service life of the pump. Under normal use, the rotor parts such as the lower impeller run for 8000 hours without replacement. The service life of the pump body is more than 10 years. At present, the flow rate of this series of pumps produced by the company is less than or equal to 1200m³/h, and the lift is less than or equal to 1500m.

Characteristics

1. New structure: rotor parts with symmetrical arrangement of impellers can basically cancel the axial thrust generated by the positive and negative impellers during operation, so that the balance disc device which is easy to wear and fail is not needed. It breaks through the traditional structure of multi-stage pumps.

2. High efficiency and energy saving: Because the pump rotor has no wear and axial pulsation of the balance disc, the impeller and guide vane are always in the best state, unlike ordinary multi-stage pumps with the wear of the balance disc, the rotor parts move forward and the efficiency appears significantly decreased. The average efficiency is 2%~14% higher than that of ordinary multi-stage pumps.

3. Low maintenance rate: Precision casting reduces vulnerable parts and the number of maintenance and disassembly, prolongs product life and reduces maintenance costs.

4. Good cavitation performance: The optimized hydraulic model and structural design, precision casting and wear-resistant materials make the pump have good anti-cavitation performance, making the whole machine run smoothly and with low noise.
