Industrial Boiler Feed Multistage Pump

DG series industrial boiler feed multistage pump is a kind of horizontal, segmental centrifugal pump with multiple stages.It is used to pump clean water or other liquids with similar properties.
These pumps work well for medium and low pressure boiler feed water.They can also be used for high-pressure water supply and drainage in factories and cities.The liquid temperature can be between -20°C and 150°C.The inlet pressure should be less than 0.6 MPa.

Mainstream structure

1.Pump casing: industrial boiler feed multistage pump's casing is made up of suction section, middle section and discharge section, held together by stay bolts. Inlet and outlet are both facing vertically upward.

2.Rotor: Consists of pump shaft, multistage impellers and balance disc. It rotates and increases liquid pressure.

3.Axial thrust balancing: Balance disc or balance drum is used to balance axial thrust, so the pump runs steadily.

4.Bearings: Can be sliding or rolling bearings, lubricated with thin oil and cooled by water. They work well in high-temperature conditions.
5.Shaft seal: Mechanical seal or packing seal. It stops leakage and can withstand high temperature.

Advantage

1.High head and stable pressure: Industrial boiler feed multistage pump mostly uses a multi-stage impeller structure, which can achieve a head of several hundred to several thousand meters to meet the needs of medium-high pressure and ultra-high pressure boilers. It is equipped with a precise pressure regulating device to offset load fluctuations, preventing equipment damage and operational impact caused by abnormal pressure.

2. Strong flow adaptability: It has a wide flow adjustment range. It can accurately match the changes of boiler load through frequency conversion and other methods, meeting the water supply needs of full load, low load and start-stop stages, and avoiding energy waste and insufficient water supply.

3. Energy efficient: Industrial boiler feed multistage pump optimizes hydraulic design to reduce energy loss, and is matched with high-efficiency motors and frequency conversion systems. It can adjust the speed dynamically, with high operating efficiency. Long-term use can significantly reduce power consumption and operating costs.

Typical Applications

1.Water supply for industrial boilers

2.Water supply for high-rise buildings and municipal water pressure boosting

3.Mine drainage and oil field water injection

4.Industrial water circulation and cooling systems

5.Water treatment, fire fighting pressure boosting, and high-pressure delivery in chemical processes.
