ISW series single-stage single-suction vertical(horizon- tai)fixed-type fire-fighting pump unit (pump)is a brand new product designed and produced by this Co.upon the demand of industrial and mineral enterprises,engineering construction and high buildings for fire-fightingand strictly according to the international standard ISO2858 and the latest national standard GB6245-1998, Performance requirements and testing methods of fire-fighting pumps.
The products approved with its sealed sample tested by the national fire-fighting equipment quality super vising & testing centre,fully conforming the requirements in GB6245- 1998 and its performance reaches the advanced level of the same domestic ones.
ISW series pumps can be used to transport liquids below 80 ° C without solid particles or similar physical and chemical properties to water, as well as light corrosive liquids.
This series of pumps is mainly used in industrial and civil building fixed fire systems (hydrant fire extinguishing system, automatic sprinkler system and water spray fire extinguishing system, etc.) water supply.
ISW series pump performance parameters in the premise of meeting the fire conditions, taking into account the requirements of living (production) water supply conditions, the product can be used for independent fire water supply system, but also for fire, living (production) shared water supply system, can also be used in construction, municipal, industrial and mine water supply and drainage and boiler water supply and other occasions.

The pump is a single-stage single-suction centrifugal pump, and the installation form is vertical or horizontal.
It can be installed in multiple ways according to the field conditions. And according to the flow, pressure requirements using parallel, series method to increase the required flow, pressure.
The bearing adopts low noise closed bearing, which has been injected with grease when leaving the factory, and can ensure continuous operation for more than two years. And the concentricity of the component is high, the pump impeller has excellent dynamic balance, the running vibration is small, and the use environment is improved.
The shaft seal of the pump is mechanically sealed, which solves the severe leakage of the conventional centrifugal pump packing, prolonging the service life and ensuring the clean and tidy operation site.
Pump material
a. Pump shaft - stainless steel
b. Impeller - cast steel
c. Pressure parts - cast iron HT250 or QT400-18
When the pump rotates, the parts that may produce friction are made of wear-resistant, corrosion-resistant and high-anti-bite material combination to ensure reliable operation, reduce noise, and avoid producing rust water, blocking spray and other fire protection devices, greatly extending the service life and avoiding rust and bite after shutdown.
