DG Multi-stage High-temperature Boiler Feed Water Pump

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 water 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.

Materials of hot water pump

DG centrifugal boiler feed 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.

Characteristics of multistage boiler feed pump

High efficiency, easy installation and maintenance: the use of high-efficiency and energy-saving hydraulic model. This series of pumps has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc.

Shaft seal: soft packing seal or mechanical seal is adopted, the seal is safe and reliable, the structure is simple, and the maintenance is convenient and quick.

<120℃ Ordinary mechanical seal

120℃<160℃ Cartridge seal

The whole machine has a long service life: the shaft is a fully sealed structure, which ensures that it does not come into contact with the medium, does not corrode, and has a long service life.
