CHINA FACTORY XBD-S DOUBLE SUCTION HORIZONTAL SPLIT CASE FIRE PUMP. XBD-S SERIES OF FIRE FIGHTING PUMP MANUFACTURERS, FACTORY, SUPPLIERS FROM CHINA

XBD-S single-stage double-suction split volute type fire pump uses prototype impeller and modified impeller and its cutting, with full and broad model spectrum and high use efficiency. The pump at the working point of any flow head. It adopts the excellent hydraulic model at home and abroad that can self-balance axial force and radial force, with stable performance, high efficiency, compact structure, low vibration, high pressure resistance of the pump body, and convenient installation and maintenance. It is mainly used for pressurized water supply in fire protection systems, and can also be used in water supply plants, irrigation, drainage pumping stations, power stations, air-conditioning circulating water, industrial water supply systems, fire protection systems, shipbuilding industry, oil refining systems, mining and other occasions for conveying liquids.

 

XBD-S fire pump set can be used to transport clean water without solid particles and liquids with physical and chemical properties similar to water. It is mainly used for pressurized water supply of fire protection system, and can also be used in factories and mines, water supply and drainage of high-rise buildings, long-distance water supply, heating, bathroom, boiler hot and cold water circulation pressurization, air conditioning and refrigeration system water supply and equipment matching and other occasions

 

1. Built-in sealing lubrication structure: The pump has a built-in sealing lubrication structure, and the lubrication and flushing of the sealing system of the pump by the sealing circulating water is more direct and effective.

2. Beautiful appearance: the straight-line appearance and the strong ribs are attached to the pump cover. The built-in sealing and lubricating structure makes the overall structure of the pump seamless, and the flexible structure design makes the pump more elegant and elegant.

3. High efficiency: CFD is used to calculate fluid dynamics, and the relationship between the pressure distribution and velocity distribution in the pump is analyzed and calculated, and the flow channel design of the pump is optimized to ensure that the pump has an efficient hydraulic profile and improve the efficiency of the pump. The pump body adopts dual flow channel design to reduce radial force. The pump body, pump cover, impeller and other overcurrent parts are molded with resin sand board, which ensures the appearance and size of the flow channel as well as the hydraulic efficiency of the pump.

4. High balance precision: The dynamic balance precision of rotor parts is G1.0.

5. Shaft: The shaft is short and rigid, and the shaft diameter is increased to prolong the service life of the bearing and mechanical seal. The shaft is a fully sealed structure, which ensures no contact with the medium, no rust, and long service life.

6. Double volute: The high-lift pump adopts a double volute structure, which reduces the radial force.

6. Precautions for the use of XBD-S single-stage double-suction split volute fire pump 

1. The fire pump adopts stainless steel shaft and aluminum bronze impeller (national fire protection acceptance standard). If there are different material requirements, please specify separately when inquiring (ordering).

2. The fire pump should be started at least once every six months to prevent it from being difficult to start again due to corrosion caused by long-term use or poor maintenance.

3. This pump is especially suitable for fire protection occasions requiring large flow, with stable performance.
