from the hydrant to the water pump. It shall be an automatic balanced pressure foam

proportioning system and it shall be designed to follow the main characteristics as

mentioned in the NFPA 1901 standard.

It shall offer a highly accurate foam proportioning ratio injected into the water

stream at each individual outlet (no exceptions). It shall be possible to select the

proportioning ratio at each outlet at 3 different percentages from 0% to 6% with a

high accuracy, independent of the actual flow. The system work shall work fully

automatic and it shall consist of a foam compound pump with a separate drive motor,

a fire-fighting centrifugal pump for water and the pressure proportioners.

It shall be designed for water supply directly from the hydrant with pressure up

to 10 bar directly to the water pump.

The automatic balanced pressure foam proportioning system shall be fully

controlled by electronic differential pressure control unit. Manual operation shall be

possible. Discharge of foam solution and water at different discharge outlets with

different foam admixing rates shall be possible. The foam proportioning system shall

be suitable for all kinds of class B foam concentrated including AFFF.

7 On each delivery outlet an own balanced-pressure foam proportioner shall

be installed. This proportioner shall consists of a casing, an integrated spring loaded

excenter flap, two injection nozzles for foam compound as well as two ball type

valves for the foam supply.

Depending on the water throughput in the pressure proportiner, the excenter

flap shall open or close the inlet aperture of the foam supply.

That means if less water is pumped, the excenter shall open less and in the same

way less foam agent shall be admixed. If more water is pumped, the excenter flap

shall open more and more foam agent shall be admixed. The foam compound shall

be supplied via 2 lines to 2 different sizes of excentres.

Therefore, it shall be possible to choose 3 admixing rates (rate 1, rate 2 and

the sum of 1 + 2), between 2 and 8%. If the foam supply is closed, only water shall

be delivered to the pressure outlet. A change of the operation method or admixing

rate shall also be possible during operation. The accuracy of the foam proportioning

shall be much better than in usual systems and it shall be less than +/- 10% of the

adjusted percentage rate, depending on the viscosity of the foam compound.

One pressure proportioner shall be fitted in the monitor line for the large

throughput volume of not less than 6900l/min. It shall be possible to adjust the

admixing rate from 1 to 8% in steps of 1%. The system shall have different metering

discs responsible for proportioning rate. Replaceable discs shall allow the selection

and mounting of three (3) discs at a time to suit desired proportioning ratios.

Pressure preselection and automatic water pressure control system: By means of a selector switch the water pump pressure shall be pre-selected.

An electronic control unit shall keep the output water pressure at a constant level,

independent of the hydrant inlet pressure and of the discharged water or water/foam

volume. The whole installation shall be able to work automatically without pump

operator.

The following shall be incorporated in the foam admixing system:

The foam proportioning system shall be suitable for all foam compounds

based on Protein, Fluroprotein, Synthetic and Aqueous film forming type (AFFF) as

also for use with soft or brackish water.

No recirculation back to the foam compound tank in case of high foam pump

speed and low foam request.

Simultaneous operation with water and foam (on all delivery outlets) due to

balanced-pressure foam proportioner on each delivery outlet.

The water pump shall be never in contact with foam agent.

8 It shall be possible to supply foam to each delivery outlet in a range between

200 and 1200 l/min.

Automatic foam proportioning system, independent of water pressure,

therefore exact proportioning for the whole pump output.

Individual adjustment of foam proportioning rate on each pressure outlet, even

during operation shall be possible.

Hydrant operation (not less than 11 bar inlet pressure) with water supply from

hydrant directly to the water pump, even during foam operation, it shall be possible

without reduction of hydrant pressure.

Filling of the foam compound tank via foam pump.Delivery of foam compound

of the vehicle’s own tank into other installations or containers (stationary installations

or vehicles). The layout drawings of the foam system shall be provided.

FOAM PUMP The foam pump shall be a three stage medium pressure centrifugal pump. It shall be made of gun metal and priming shall be done by double piston priming pump.

Discharge rate : not less than 500 l/min. at 15 bar Max.pressure : 18 bar Drive: The foam pump shall be driven by a self contained Diesel engine with an output of not less than 36,5 KW at 3150 rpm. The engine shall be insulated against noise. Instead of a second P.T.O. a separate diesel engine shall be used to vary the speed of the foam concentrate pump to accurately balance the foam concentrate pressure to the water pressure. Only the required amount of foam concentrate shall be delivered to meet the demand.There shall be no recirculation of the foam compound into the foam tank (no exceptions).

The offered foam proportioning system shall offer the advantage that the hydrant inlet pressure is sufficient enough to work with the separate diesel engine/foam compound unit independently, that means the water pump shall be switched off. Foam Pump Connections: One valved tank filling line
