Foam pump variable-flow proportioning systems are highly reliable
solutions that ensure the precise and balanced mixing of water and
foam concentrate during firefighting. These systems are particularly
preferred in high-risk applications such as industrial facilities,
refineries and fuel filling stations, hangars, storage areas, and
sites containing hazardous materials.
Gear-type positive displacement pump sucts foam concentrate from the
atmospheric foam tank and delivers it to the pressure balancing valve.
The pressure balancing valve precisely regulates the pressure in the
foam and water lines by returning excess foam concentrate to the foam
tank, ensuring the correct amount is directed to the foam
proportioner. The foam proportioner, at balanced pressure, provides a
mixture at 1%, 3%, or 6% ratios, producing the foam solution. The
system can be integrated into both fixed-flow and variable-flow
firefighting systems.
Atmospheric Foam Concentrate Tank
Atmospheric Foam Concentrate Tank
They are manufactured by us in vertical or horizontal design from
316L grade stainless steel sheets, in dimensions tailored to your
needs. The production is carried out in accordance with EN
standards, and the products are delivered to the customer together
with all quality documents such as ITP, WPS, PQR, EN 10204 - 3.1
material certificates, and hydrostatic test reports.
Positive Displacement Foam Pump
Positive Displacement Foam Pump
Positive displacement foam pumps with bronze body, phosphor bronze
gears, and hard chrome plated stainless steel shaft are suitable
for use with all types of foam concentrates. They are also
compatible for operation with seawater. The pumps can be supplied
with electric motor, water turbine, or diesel engine drive
options.
Pressure Balancing Valve
Pressure Balancing Valve
Pressure balancing valve is a special valve used in pump-driven
foam proportioning systems to equalize the pressure difference
between water and foam concentrate. Its purpose is to match the
foam concentrate pressure with the system’s water pressure,
ensuring that the foam proportioner operates under balanced
pressure conditions.
It is a diaphragm-type valve with a bronze body and stainless
steel internal components. By returning the excess foam
concentrate coming from the foam pump back to the foam tank, it
balances the foam pressure with the water pressure.
Variable Flow Foam Proportioner
Variable Flow Foam Proportioner
Foam proportioner: In pump-driven foam proportioning systems, it
ensures the correct mixing of water and foam concentrate at
balanced pressure (e.g., 3% or 6%).
It is a Venturi-type device with a bronze body and bronze internal
components. It is manufactured in 4 in, 6 in, and 8 in sizes for
different flow ranges.
