The WPS Triple Foam System is easy to install and operate! This system uses 3 rugged, air-operated, double-diaphragm Warren-Rupp pumps to either draw ready-to-use chemicals or to draw water and chemical concentrate from static tanks and accurately blend them using precision metering tips. Thick, rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. The foam is then evenly projected through the 6' foam stick assemblies. A fixed flow rate allows the user to use just one air valve to adjust the foam quality for all 3 foam sticks simultaneously. This system is great for retrofitting and for new installations.
