Product Features

XBD-SC fire-fighting constant-pressure tangential pump (horizontal type) has the characteristics of variable current voltage regulation, that is, within the full flow range, the head change is not large, basically has the characteristics of quasi-constant pressure, so it is called constant temperature of XBD system. The fire pump, this performance characteristic fully meets the use characteristics of the fire site, thus avoiding the phenomenon that the ordinary centrifugal pump is overpressured at a small flow rate in the fire fighting site and cannot be supplied with water at a large flow rate.

According to the characteristics of the constant pressure fire pump itself, combined with the specific conditions of our company, the constant pressure fire pump adopts a horizontal structure. For the constant pressure fire pump of 75kW or less (including 75kW), the vertical structure can also be adopted. The whole series adopts the Y2 type direct-coupled motor with extended shaft, which eliminates the coupling, which greatly improves the reliability of the pump unit; constant pressure The fire pump adopts a radial open impeller, axial force trachoma, and no ring, which eliminates rust and seizure, thus making it run smoothly, with low noise and long service life.

The pump casing is made of cast iron, and other over-current components can be made of stainless steel, bronze or other corrosion-resistant materials according to the specific needs of the user.

Use

XBD series constant pressure fire pumps are mainly used for water supply in industrial and civil building fixed fire protection systems (fire hydrant fire extinguishing system, automatic sprinkler system and water spray fire extinguishing system). In addition, they can also be used for fire fighting and living (production) sharing. Water supply systems and construction, municipal, industrial and mining, boiler water supply and other occasions.

Working conditions
