Optimum performance of these inline eductors is achieved with 200 psi (13.8 bars) inlet pressure. These eductors are rated to flow 60, 95, 125 or 250 gpm (227, 360, 473 or 946 Lpm) @ 200 psi (13.8 bars) inlet. Although they are capable of operating at inlet pressures as low as 70 psi (4.8 bars), in most cases adequate residual firefighting pressure at the nozzle requires that the eductor inlet pressure be at least 100 psi (6.9 bars), or greater. Lower inlet pressure will result in lower flow and affect the proportioning rate.
Eductor body and venturi jet are constructed of corrosion-resistant brass. The positive setting metering value can be set at 0, 0.5, 1, 3 or 6%. Standard water inlet is a (F) NPSH connector and the outlet (M) NPSH connector. Each eductor is supplied with a 36” (0.9 m) clear PVC concentrate pick-up hose.
