High pressure Horizontal Multistage High Head Water Pumps Manufacturer
1.QD Multistage Water pump introduction
Model QD (G) pump is a horizontal multi-stage centrifugal pump and suitable for transporting pure water (with the contained foreign matters' content less than l % and graininess less than 0. 1mm) and other liquids of both physical and chemical natures similar those of pure water.
QD model middle and low pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 105ºC, and is also applicable for small boiler water supply or transporting medium similar to hot water.
Performance range of model QD series
Flow: 3.75-185 m3/h
Corollary power: 4.0-400kW
Head: 69-684m
Inlet diameter: 40-150mm
QDG model hypo-high-pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 160ºC, and is also applicable for small boiler water supply or transport medium similar to hot water.
Performance range of mode QDG series
Flow: 1 5-3 00m3/h
Corollary power: 75-1 250kW
Head: 390-1050m
Inlet diameter: 65-200mm
2.QD(G) Multistage Water pump Structure and Feature
1.Multistage pump compact structure, small size, beautiful appearance, its vertical structure decided small installation area, its centre of gravity overlap center of pump foot, thus enhancing the running stability and service life of the pump.
2. The multistage pump can meet different requirements by increasing or decreasing the pump stages combining cutting impeller diameter, without changing the installation area, and this is the multistage pump special own.
3. Pump rotor is provided with low windability to achieve smooth operation, littlevibration, low noise and long service life .
4. According to the needs, the suction and discharge nozzles can be installed into the same direction, several different directions in order to meet different connection.
5. Motor plus outer rain cover, pump can be placed in the outdoor use, cancel the pump room, save construction cost.
3.QD Multistage Water pump Application
Multistage centrifugal pump application scope is widespread, such as medicine, food, chemical industry, irrigation, pressurization, distillation, brewing, fire control, water supply, sewage treatment, electrical and mechanical, printing and dyeing industry, seawater desalination, ship equipment and supporting pressure tank and all walks of life, wide range of uses.
Like:
Cooling water, hot water
Water supply/distribution
