1. Summary
XBD-DL series fire-fighting pump is designed with advanced know-how and made of quality materials and features high reliability (no joining-up world occur at starting after a long time of unuse), high efficiency, low noise, small vibration, long duration of running, flexible ways of installation and convenient overhaul.It has a wide range of working conditions and a flat flow-head curve and its ratio between the heads at both shut off and design points is less than 1.12 to have the pressures garded to be crowded together,benefit to pump selection and energy saving. Tested by National Fire-fighting Equipment Quality Supervising and Testing Center, all performances of the product conform the requirements of GB6245-1998 Preformance requirements and testing methods for fire-fighting pumps and get to the advanced level of the same ones in the country.

3. Application                                                                                                                                                                                                         XBD-DL series pump can be used to transport the pure wa-ter below 80 ℃ and containing no solid grains or the liquids
with similar physical and chemical natures as those of pure water as well as the liquids lightly corrsive.
    It is mainly used for the water supply for the fixed fire-figh-ting system of both industrial and civil buildings (fire hydrant
fire-extinguishing system,automatic spraying fire-extinguishing system and fog-spraying fire-extinguishing system etc.)
   The performance parameters of the pump can also meet with the working condition requirements for living (production) water supply under the prerequisite to meet with the working conditi-ons of fire-fighting,that is it can be used in an individual fire-fighting, water supply system and also in the mutual water supp-ly system of both fire-fighting and living(production), as well as in the water system of buildings, municipal works, industry and mines and boilers.
