DINKONDA GLOBAL Power Plants Special 3.75- 1352m³/h, 50-1850m DG Type Multi-stage Boiler Feed Pump Horizontal Multi-stage Single Suction Segmental Centrifugal Pump

Product Overview
The DG type multi-stage boiler feedwater pump is a horizontal multi-stage single suction segmental centrifugal pump, suitable for conveying clean water with a temperature of -20~280 ° C, or non corrosive liquids with physical and chemical properties similar to water. The maximum head can reach 1800 meters, and it has the characteristics of wide performance range, high operating efficiency, and long service life. It is currently a widely used boiler water pump in the market. This pump replaces the old GC type boiler feedwater pump and adopts a horizontal installation and multi-stage stage structure, which runs smoothly and is easy to install and maintain. Multi stage boiler feedwater pump is one of the important boiler pumps in power plants and heating systems. The task of multi-stage boiler feedwater pump is to deliver the feedwater with a certain temperature and peroxide removal from the deaerator storage tank to the boiler after increasing the pressure, ensuring that the liquid level in the boiler maintains the technical height. Therefore, the boiler water pump must operate continuously, otherwise it directly affects the safety of the boiler equipment. Multi stage centrifugal pump is undoubtedly an ideal boiler water pump.

Product Advantages
Structural characteristics of DG centrifugal multi-stage boiler feed pump
The DG type multi-stage boiler feed pump adopts a D-type multi-stage centrifugal pump structure, which is divided into five parts: stator part, rotor part, sealing part, bearing part, and balance part.

1. Stator section:

The DG type multi-stage boiler feed pump consists of a pump body (inlet and outlet sections, middle section), guide vanes, etc., which are fastened by screws through tie rods, forming a sealed working chamber.

2. Rotor section:

The DG type multi-stage boiler feed pump consists of a shaft, impeller, shaft sleeve, and balance disc device. Through shaft transmission, the impeller rotates to generate centrifugal force, thereby driving the flow of the medium.

3. Bearing section:

The DG type multi-stage boiler feed pump consists of a bearing body, bearings, and bearing covers. The bearings play a role in supporting the shaft and ensuring its normal and stable operation.

4. Sealing part:

DG type multi-stage boiler feed pumps are divided into packing seals and mechanical seals. Packing seals are mainly used in situations where leakage requirements are not strict on site or where the medium contains solid particles. Mechanical seals are suitable for high temperature, high pressure, and corrosive situations where leakage is strictly required. Both seals play a sealing role at both ends of the pump, preventing the outflow of medium from the pump body and ensuring the sealing performance of the pump body.

5. Balance section:

Due to the unequal compression area of the front and rear cover plates of the DG type multi-stage boiler feedwater pump impeller, axial force is generated, which is eliminated by the balance device. The balance device inside the pump consists of a balance plate, balance ring, and balance sleeve. The balance chamber of the pump consists of a discharge section (outlet section), a packing box (tail cover), and a balance water pipe component connected to the suction section (inlet section). The balance water pipe must not be blocked, and the balance water volume inside the balance water pipe can be adjusted with a valve.

6. DG type multi-stage boiler feedwater pump complete set scope: complete supply of pumps, motors, check valves, gate valves, common bases or their own bases.
