XBD-S Type single-stage double suction open volute fire pumpDetailed product description：

1、 Product Overview:

The XBD-S single-stage double suction open volute fire pump is a high-performance water pump produced by our company with advanced technology introduced from Germany. By using prototype impellers and modified impellers and their cutting, the pump has a full and wide profile and high efficiency. Within the performance range of the profile, it can provide a pump with any flow head working point that appropriately meets the needs of users. It adopts the most excellent hydraulic model that can self balance axial and radial forces at home and abroad, with stable performance, high efficiency, compact structure, low vibration, high pressure resistance of the pump body, and easy installation and maintenance. Mainly used for boosting water supply in fire protection systems, it can also be applied to water treatment plants, irrigation, drainage pump stations, power stations, air conditioning circulating water, industrial water supply systems, fire protection systems, shipbuilding industry, oil refining systems, mining and other occasions for transporting liquids.

2、 Product features:

1. Built in sealing lubrication structure: The pump has a built-in sealing lubrication structure, and the sealing circulating water provides more direct and effective lubrication and flushing of the pump sealing system.
2. Beautiful appearance: The straight shaped appearance is reinforced with strong ribs on the pump cover, and the built-in sealed lubrication structure makes the overall structure of the pump integrated. The flexible structural design makes the pump more exquisite and generous.
3. High efficiency: CFD computational fluid dynamics is used to analyze and calculate the relationship between pressure distribution and velocity distribution inside the pump, optimize the flow channel design of the pump, ensure that the pump has an efficient hydraulic profile, and improve the efficiency of the pump. The pump body adopts a dual channel design to reduce radial force. The flow parts such as the pump body, pump cover, impeller, etc. are molded with resin sand plates to ensure the appearance, flow channel size, and hydraulic efficiency of the pump.
4. High balance accuracy: The dynamic balance accuracy of the rotor components is G1.0 level.
5. Shaft: The shaft is short and has good rigidity. Increasing the shaft diameter can extend the service life of bearings and mechanical seals. The shaft is a fully sealed structure, ensuring no contact with the medium, no corrosion, and a long service life.
6. Double volute shell: The high lift pump adopts a double volute shell structure, which reduces radial forces.
