HR DBL series stainless steel vertical multistage pump

Product Overview:

HR DBL type pumps are vertical, single-suction, multi-stage, segmented centrifugal pumps, suitable for urban water supply and central heating systems. It is used to transport clean water or liquids with physical and chemical properties similar to clean water.

The impeller, guide vane and other components of the stainless steel vertical multi-stage pump are made of stainless steel plate pressed and laser welded, with high surface finish, small hydraulic flow loss, and easy to clean the interior, which is very beneficial for conveying pure media.

Since the impeller is made of stainless steel plate pressing and welding, some casting impellers are difficult to achieve small flow and high lift pumps can be easily realized.

HR DBL type pump is a vertical multi-stage pump structure, which occupies a small area, has high efficiency, beautiful appearance, light weight and low operating noise.

Material and structure description:

The general material of the main overflow parts of the HR DBL pump is 304.

1.HR DBL type pump is a vertical multi-stage pump, the overall structure is a pipeline type arranged in the pipeline, and the footprint is small, the pump may not disassemble the pipeline during maintenance;

2. The pump shaft and the motor shaft are connected by a split-type rigid coupling, which can be easily connected and unloaded, and can accurately ensure the neutrality of the pump shaft and the motor shaft;

3. The shaft seal of the pump adopts a container mechanical seal, which is convenient for loading and unloading; and there are a variety of mechanisms and materials for Xuanyuan to ensure safe use;

4. The impeller, guide vane and other components of the pump are made of stainless steel press and welding. The pump body and pump cover are generally precision cast, which is easy to clean and has a beautiful appearance.

Scope of application and working conditions

The parts of the pump are pressed with stainless steel plates and laser welded, and there are various grades of stainless steel to choose from. Therefore, the HR DBL pump is widely used, mainly suitable for conveying various clean water and light corrosive liquids. It can be used for:

Residential water supply and pressurization

Industrial boiler feed water

Air conditioning system circulating water

Water Treatment and Reverse Osmosis Systems

Water for food industry and pharmaceutical industry

Types of conveying liquids: various clean water and lightly corrosive liquids;

Pump chamber pressure: ≤ 4.0MPa
