XBD-HYD vertical multistage constant pressure tangential fire pump

Product characteristics

XBD-HYD series vertical multi-stage constant pressure tangential fire pump has the characteristics of variable current pressure regulation, that is, in the full flow range, the head does not change much, when the pump changes from zero flow to the required flow range, its head changes in the range of 5%, and small flow or zero flow no pressure, Thus, the phenomenon that the ordinary centrifugal pump can not supply water when the flow is small and medium at the fire fighting site is avoided. Greatly improve the efficiency of fire fighting and the reliability of fire equipment and fire personnel.

According to the characteristics of the fire pump combined with the situation of our company, the impeller of the final stage of the pump is open, the axial force is small, no mouth ring, and the phenomenon of rust bite is prevented. The multi-stage impeller is closed, the number of impeller is small, and the bronze material is not easy to rust and bite. The pump body and cover are made of cast iron, and the impeller is adopted according to the user's requirements.

XBD-HYD series vertical multi-stage constant pressure tangential fire pump compared with similar fire pumps, the volume of the pump with the same flow pressure specifications is reduced by 30%-50% to reduce the floor area and space of the pump. Its type spectrum distribution is reasonable, can well adapt to the fire protection needs of different floor management, meet the design selection, and the product has reached the high level in China. It has the advantages of small footprint, light weight, excellent performance and reliable operation. It has high cost performance and is the ideal product for users to choose fire pump.

XBD-HYD series vertical multi-stage constant pressure tangential fire pump, the direction of the import and export flange can be 0°, 90°, 180°, 270° relative to the direction of the suction inlet as required. (Single stage pump does not allow 0°)

Product overview

XBD-HYD series vertical multi-stage constant pressure tangential fire pump is a new product developed by our company according to market demand, which is suitable for high-rise building fire water supply and domestic water supply. It is a reliable and high-quality fire pump. Its performance and technical conditions meet the requirements of the national standard GB6245-2006 "fire pump performance requirements and test methods" standard.

XBD-HYD series vertical multi-stage constant pressure tangential fire pump is mainly suitable for industrial and civil building fire system (fire hydrant fire extinguishing system, automatic spray system and water mist fire extinguishing system) water supply, but also can be used for fire and life (production) shared water supply system and building, municipal, industrial and mining, boiler water supply and other occasions.
