During operation of a SEM-SAFE
®
High-Pressure Water Mist Pump Unit with supply manifold
instead of unit tank, the water under low pressure (min. 1-3 bar) is delivered from an outside reservoir
into the supply manifold on the SEM-SAFE
®
High-Pressure Water Mist Pump Unit. Delivery is
performed either with the help of a booster pump between the reservoir and the supply manifold or
with the reservoir tank placed on a higher level than the SEM-SAFE
®
High-Pressure Water Mist
Pump Unit, ensuring positive water flow.
From the supply manifold, through the hoses, water is discharged into high-pressure pumps, which
are raising the water pressure to system pressure. Then, water under high pressure reaches the water
mist nozzles in protected areas.
The picture below shows an example of a SEM-SAFE

High-Pressure Water Mist Pump Unit with
the supply manifold. A detailed description of components is presented in the following chapters.
