Constant pressure tangential pump has the characteristics of variable voltage regulator, that is, in the entire flow range, the lift change is not big, the pump from zero flow to the required maximum flow range changes, the head changes in 5% Range, and the small flow or zero flow does not overpressure, thus avoiding the ordinary centrifugal pump in the small flow over-pressure and large flow of water is not on the phenomenon, greatly improving the fire extinguishing efficiency and fire safety equipment and firefighters reliability. Working conditions: Speed: 2900r / min (synchronous motor speed) Medium temperature: water at room temperature Flow range: 0 ~ 80L / S Head range: 30 ~ 260m Motor power: 15 ~ 160KW Constant pressure tangential pump features The entire series are used to increase the shaft Y-type straight motor, the pump compact, nice, small size, reliable mechanical seal, which greatly improves the reliability of the pump unit; pump impeller are open, small axial force, no ring, it stopped Rust and bite, so the pump system runs smoothly, low noise, long service life, easy to use and maintenance; pump body, pump cover cast iron, impeller according to user requirements using ductile iron or bronze material. Vertical constant pressure fire tangent pump Constant pressure tangent pump widely used XBD series constant pressure fire pump is mainly applied to industrial, civil buildings fixed fire fighting system (fire hydrant fire extinguishing system, automatic sprinkler system and spray fire extinguishing system) Can be used for fire and life (production) shared water supply system and construction, municipal, mining, boiler feed water and other occasions.
