FOAMJET 25E is positive pressure proportioning system (EN 16327-PPPS) with digital control used to maintain selected constant foam-water proportion regardless of water flow fluctuations. The system accurately delivers foam concentrate from 0.1 % to 8 % through a check valve/injector fitting, directly into the water discharge stream of the fire pump.
The proportioning system uses electrically driven foam pump. The pump and motor drive are designed for long-term load with over-temperature and current protection. High quality industrial components as well maintenance-free brushless motor (BLDC) ensure top performance of the injection system.
