Model QD (G) Multistage pump

The Model QD (G) multistage pump is a horizontal, multi-stage, centrifugal water pump and it is 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 to those of pure water. The QD multistage pump can meet different requirements by increasing or decreasing the pump stages combining cutting impeller diameter, without changing the installation area. The QD series Multistage centrifugal pump widely usd in medicine, food, chemical industry, irrigation, water supply, pressurization, distillation, fire fighting system and other conditions need high pressure.

I. Overview
Model QD (G) multistage  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 to those of pure water.

II. Features:
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.

III. Aplications:
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
Water supply/distribution
Fire protection
Metal manufacturing
Irrigation
General industrial services
Sea water
