A gas pump unit for use with the HI-FOG® water mist fire protection system.
For use with the HI-FOG® water mist fire protection system only.
The GPU pump is propelled by pressurized air or nitrogen. The pump is a piston-type pump with two double chambers. The gas is also used as an atomizing medium by feeding it into the system either directly (DF) or via water cylinder (WF). The feed water can be taken from a tank or from an external water supply. The pump starts when the propelling gas flows to the pump. A stand-by pressure of about 25 bar is maintained in the system by a pneumatic pump.
At each stroke, constant volumes of water and gas are discharged into the network. The operating pressure in the system is time-dependent: the pressure at the sprinklers gradually decreases from (80 ± 10) bar down to zero depending on the number of the gas cylinders.
The water and gas supply of each system is dimensioned to provide the total suppressant required typically for that application. The maximum flow of the pump unit is 120–150 L/minute initially. The discharge may be interrupted at any time by closing the shut-off valve.
The unit operation does not require any electrical power. Electrical power is applied for controlling, monitoring and signalling of the system performance as described in contract-specific requirements.
