Description
Injects foam into high pressure moving water streams
- Reliable operation
- Accurate proportioning over wide range of flows and pressures
- Compatible with all fire fighting foams and potable or sea water
- Fixed or portable versions available
The Angus Fire Polaris foam induction system comprises a water motor coupled directly to a foam pump. The 8-vane water motor is fitted into the main water supply pipe and is driven by the water pressure. The motor is a fully sealed unit so no water is lost during this process. The rotation speed of the water motor is directly proportional to the water flow rate.
The water motor is coupled via a shaft to either one or two positive displacement foam injection pumps, which draw foam from a storage tank and into the main water pipe downstream of the water motor.
The water motor speed is directly proportional to the water flow rate, and as the water motor output shaft is connected directly to the foam injection pump(s), the foam induction rate will always be directly related to the water flow over a wide range of flows and pressures.
The energy-efficient design of the 8-vane motor only utlilises the power necessary to drive the foam induction pumps. This minimises the pressure loss in the main water stream.
