Product Description

Generally used in:

Boiler pumps are actually multi-stage pumps, which are mainly divided into two categories: vertical and horizontal.
1. The horizontal boiler water pump is also a very early developed boiler water pump product. It has the characteristics of high efficiency, energy saving and stable performance. The suction and discharge ports of the horizontal boiler water pump are vertical.
2. The principle of the vertical boiler water pump is the same as that of the horizontal boiler feed pump. The difference is that the vertical boiler feed pump is light in weight, and the pump body and over-current parts are made of stainless steel, which has changed the previous pump. The production process of such products that need to be cast is all made by advanced stamping technology and knife-light welding technology. The efficiency of the whole machine is greatly improved, the power consumption is greatly reduced, and the energy saving effect is completely achieved.

Classification and application:

1. GC type horizontal boiler feed pump
This type of horizontal multi-stage pump is a multi-stage segmental centrifugal pump. The inlet and outlet of the water are upward. The general material is cast iron. It transports boiler water with a temperature below 105℃. Boiler feed water for small factories.

2. DG type boiler feed pump
This type of boiler feed water pump is used the most, it is installed horizontally, the inlet and outlet are all vertically upward, the axial force generated during operation is balanced by the balance plate, the temperature of the boiler water delivered is from -20℃ to 150℃, and the inlet pressure cannot exceed 0.6MPA. The flow rate of the water pump is 6~346m³, the lift is 102~800m, and it is suitable for a wide range of areas. It is suitable for boiler feed water of various low and medium pressures.

3. IR type single-stage horizontal boiler feed pump
This kind of boiler feed water pump is installed horizontally, with volute cantilever structure, simple structure, stable operation, small flow and low lift.

4. IRG type vertical single-stage boiler feed pump
The structure of this pump is vertical, and the pump is coaxial with the motor. This pump occupies a small area and is very suitable for use in buildings. The pump runs smoothly, the structure is simplified, the flow rate is small, and the lift is low. It is commonly used in small boilers water use.

5. DLR type vertical multi-stage boiler feed pump
The pump structure is vertical and consists of multiple impellers. The installation of this pump saves space and is suitable for use in houses. The pump operates without noise. There are two types of seals: mechanical seal and packing seal, which can transport heat below 150℃. When water enters the boiler, the material of the pump needs to be changed when the temperature exceeds 150℃.
