First, the product overview XBD-DL vertical multistage fire pump is my company in the original DL-type vertical multistage centrifugal pump based on 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-DL multi-stage fire pump structure Second, the product features 1, novel structure, reliable operation: canceled the balance drum (disc), the axial force using hydraulic balance, completely solve the balance drum easy to rust, easy to bite death, easy The problem of wear and tear ensures a 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: 20 ~ 230MPa Speed: 1480r / min Ambient temperature T: ≤ +40 ℃ Medium temperature: -15 ℃ ~ +105 ℃ System maximum working pressure: ≤ 2.5Mpa
