First, the product overview XBD vertical multistage fire pump is based on the original DL vertical multistage centrifugal pump according to GB6245-1998 "fire pump performance requirements and experimental methods" standard requirements improved. Mainly used for fire hydrant water supply, sprinkler system water supply, other fire fighting system water supply, other occasions, the transfer of clean liquid. XBD Vertical Multi-stage Fire Pump II. Features 1. Novel structure and reliable operation: The balance drum (disc) is canceled. The axial force adopts hydraulic balance to completely solve the problem that the balance drum is easy to rust, easy to bite and easy to wear Problems, to ensure more reliable operation. 2, less operation and maintenance costs: the use of a reliable mechanical density, low failure rate, with less maintenance costs. 3, smooth operation, low noise: the use of low-speed motor, the system has a smooth running pump, low noise and so on. 4, a unique component to reduce noise: a unique design of hydraulic components, good over-current performance, to minimize the flow noise. Third, the working conditions Flow range: 5 ~ 100L / s Rated pressure: 0.2 ~ 2.3MPa Speed: 1480r / min Ambient temperature T: ≤ +40 ℃ Medium temperature: -15 ℃ ~ +105 ℃ System maximum working pressure: ≤ 2.5Mpa
