Multistage hot water pumps are essentially multistage pumps and are primarily divided into two types: vertical and horizontal. Horizontal boiler feedwater pumps are an earlier developed type of boiler feedwater pump product, featuring high efficiency, energy savings, and stable performance. The operating principle of vertical boiler feedwater pumps is the same as that of horizontal boiler feedwater pumps. The difference between the two lies in the fact that vertical boiler feedwater pumps are lighter in weight, with the pump body and fluid components made of stainless steel, allowing for selection based on actual conditions.
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 hot water with a temperature below 105℃. Click on the picture above to view more of [GC horizontal boiler feed pump]
This type of hot 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. Click here to view more of [DG horizontal 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.

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℃. Click here to view more of [DLR horizontal boiler feed pump]
