Fire Protection System (FPS), an HD Fire dealer in Bhopal, supplies HD foam proportioning equipment: bladder tanks and ratio controllers, inline balanced pressure proportioners and pump skids, inline and portable foam inductors, foam concentrate valves and atmospheric storage tanks. These mix foam concentrate into fire water at the right ratio for fixed and mobile foam systems.
A horizontal, custom fabricated tank that stores foam concentrate for inline inductors and balanced pressure proportioning systems. It is built in stainless steel 304 or 316, or in carbon steel with FRP lining.
A pressure rated tank with a nylon reinforced Buna-N rubber bladder and a proportioner pre-piped on to it, used widely in low expansion foam systems. It can be supplied UL Listed, FM Approved or CE marked when specified.
One vertical or horizontal bladder tank acts as the central foam concentrate store for several proportioning lines, each running to its own hazard zone. Each line works as an independent proportioning system with its own foam concentrate control valve.
Two bladder tanks mounted on one skid, the first as the operating tank and the second as a standby reserve. Available as vertical or horizontal units.
A foam bladder tank supplied with the proportioner and a deluge valve already piped on to it. The bladder tank, proportioner and deluge valve are UL Listed.
Sizes: 40 & 50 mm (1.5″ & 2″ )
A by-pass valve for balanced pressure foam pump skids that sends the controlled excess of foam concentrate back to the storage tank. Offered in bronze or stainless steel in 40 and 50 mm sizes.
A hydraulically controlled stainless steel valve for bladder tank and inline balanced pressure systems that opens by itself once water supply is established. Model CV is FM Approved as part of HD's foam bladder tank proportioning system.
A foam skid engineered to the project specification, with the foam concentrate tank, foam pump, proportioner and control panel mounted on one frame. It is completely pre-assembled and tested in the factory.
A UL Listed proportioner used with a positive displacement foam concentrate pump that keeps the concentrate flow accurate over a wide range of flow rate and pressure. Several ILBPs can run from one concentrate supply line, even at different pressures.
An inductor that draws foam concentrate into the water stream and supplies foam solution to the foam making equipment, meant mainly for fixed foam installations with constant flow. Each unit is calibrated and factory tested for flow and induction rate at maximum back pressure.
Compact 65 mm inductors for manual fire fighting and mobile foam units, with a fixed flow of 225 or 450 lpm and calibration at 7 or 12 kg/cm2 inlet pressure. They are FM Approved and UL Listed with named HD foam concentrates.
The metering device of a bladder tank or inline balanced pressure system, which feeds foam concentrate into the water line in the right proportion for variable flows. It is available in stainless steel or bronze, with wafer or flanged connections.
A compact pump skid that controls the flow of foam concentrate into the water stream automatically over a wide range of flow and pressure, with no manual adjustment. It arrives ready to connect to the system.
Foam proportioning means mixing foam concentrate into the fire water at a set ratio, such as 3% or 6%, to make foam solution. Bladder tanks are very commonly used in low expansion foam systems: a pressure rated tank holds the concentrate inside a rubber bladder, incoming fire water squeezes the bladder, and a ratio controller meters the concentrate into the water line. HD offers it as a single tank, as dual tanks on a skid with one on standby, with a pre-assembled deluge valve, or with several proportioning lines serving separate hazard zones.
A balanced pressure system uses a foam concentrate pump instead. The inline balanced pressure proportioner (ILBP) works with a positive displacement concentrate pump and keeps the dose accurate across a wide range of flow and pressure, even when several injection points run at different pressures from one concentrate line. HD's skid mounted balanced pressure system packs the pump, ratio controller, by-pass valve, relief valve and electricals on one frame, covering 270 to 18500 lpm (71 to 4887 gpm) without manual adjustment. Concentrate for these systems is kept in an atmospheric storage tank.
An inline foam inductor gives a simple method of proportioning for constant flow applications. It draws concentrate into the water stream and can work against a back pressure of up to 65% of its inlet pressure, and HD calibrates and tests each unit for flow and induction rate. The portable IE225 and IE450 inductors do the same job on mobile foam units and in manual fire fighting.
Finally, confirm materials and approvals. Most items come in bronze or stainless steel, and tanks in carbon steel or stainless steel. Bladder tanks can be supplied UL Listed, FM Approved or CE marked when specified in the order. Send us the foam system flow, concentrate type and hazard details.
