Model meaning


Product introduction and characteristics

Based on the original vertical multi-stage pumps, this unit has developed a new generation of XBD pipeline type medium and low pressure fire pump products based on the latest standards of fire pumps. This series of pumps meet the requirements of fire pumps in terms of performance, structure, materials and matching. Due to the excellent hydraulic model, this series of pumps can meet the requirements of users; the vertical pump structure has the characteristics of high efficiency and wide range of performance, which can be listed in the advantages of saving space; using high-quality bearings and high-quality motors Make the pump run more safely and reliably, with low noise and small vibration; use hydraulic to balance the axial force and reduce the balance drum to make the operation more stable; its shaft seal has two forms of mechanical seal and packing seal; the pump also has in and out Features of saliva flange pipeline layout, high speed, and weight.


Application range

It is suitable for fire water supply in various places such as residences, hotels, office buildings, commercial buildings, factories, hospitals, etc.


Performance range

flow: 5 ~ 115L / s

Head: 20 ~ 230m

power: 3 ~ 200KW


Working conditions

1. It can transport clean water or non-corrosive medium with physical and chemical properties similar to clean water, and its solid insoluble matter does not exceed 0.1%.

2. Medium temperature: -15 ℃ ~ 120 ℃.

3. Maximum working pressure: XBD type pump: ≤ 2.5MPa, that is, system pressure + head ≤ 2.5MPa, XBD (I) type pump: ≤ 2.0MPa.

4. The ambient temperature is not greater than 40 ° C, and the relative humidity is less than 95%.

1. The pump is a vertical, multi-stage segment structure. The inlet and outlet flanges of the pump are on the same straight line. The impeller uses hydraulic balance to balance the axial force. There is a guide bearing at the lower end of the pump. The motor shaft is fixedly driven, and the outer cylinder is a stainless steel cylinder.
2. The shaft seal adopts mechanical seal.
3. The pump is driven by a motor. From the direction of the motor, the pump rotates clockwise.
4. An exhaust valve (gas nozzle) is provided at the pump outlet to ensure that the gas in the pump can be completely exhausted.
5. The impeller can be made of bronze material to avoid rusting between the impeller and the guide vanes after long-term shutdown.
