QDL Vertical centrifugal pump theory fire pump for fire fighting:
      QDL/QDLF series fire pumps are mainly used in the fire hydrant and automayic spray extinguishing systems etc, in the fixed fire fighting system in enterprises, institutions, project construction, high-rises and so on. The pumps deliver clean water and mediums similar to water regarding physiochemical property, not containing soild granules. The pumped medium temperature up to 120ºC.
      The pump is the third generation of our company based on the performance parameters of international  standard ISO2858 and JB/T6878.2-93, and "performance requirement and experimental method of fire pump" of GB6245-2006 issued newly by nation. it is an upgraded product of old type with flow range of 4 to 90m3/h and lift range of 15 to 250m.
 

>>> Applications:
> Fire fighting system: It is suitable for fire-fighting water supply in many places, such as communities, hotels, office building, shopping centers, factories, hospitals, etc.
> Industrial water booster system: process water system, cleaning system, high pressure flushing system.
> Industrial liquid transportation: cooling and air conditioning system, boiler feed water and condensing system, machine tool kit, acid and alkaline medium conveying.
> Water treatment: water treatment system of ultrafiltration system, reverse osmosis system, distillation system, separator and swimming pool.
> Irrigation: farmland irrigation, sprinkler irrigation, drip irrigation.

>>> Main Features:
> Long service life: Adopt excellent hydraulic model and the advanced manufacturing technology, greatly improve the performance and service life of pump.
> Running stability and  no leakage: Because of the shaft seal use hard alloy and fluorine rubber mechanical seal,  the pump can improve the reliability of the pump running and is without leakage.
> Corrosion resistance: The pump's overflow parts are made of stainless steel 304, the pump can be applied to transfer corrosive medium.
> Easy to install: The inlet and outlet of the pump is located in the same level. The fire pump can be directly connected with fire pipeline. The overall structure is compact, small volume, light weight.
> International standard motor: The pumps couple with international standard motors, the user can easily equipped with motor according to need.
> The fire fighting control cabinet can be added: According to user needs, we can provide intelligent protector to protect the pump in dry running, lack of phase, overload, etc. The control cabinet can be design for fire fighting, such as automatic fire booster control funtion, build-in fire alarm, etc.

>>> Work condition:
> Clean cold or hot water without soild and fibers. 
> Pump medium: -15ºC~+120ºC
> Working temperature: ≤+40ºC
>  Altitude: ≤1000m
If the working temperature is more than 40ºC or the altitude more than 1000m, pls let us know.
