Specially designed for commercial aquatics, the A1A enables users who require higher chemical feed requirements for sanitizing sodium hypochlorite and pH adjustment acid to move away from diaphragm technology and the inherent challenges experienced with these chemicals and adapt to peristaltic technology for less service, more trouble free and reliable chem feed solution. Features. Remote Start/Stop Nonpowered dry contact closure for remote start/stop. Pressures to 40 PSI. Variable Speed DC Motor. NEMA 4X IP 66 Washdown Duty. Patented Tube Failure Detection. Peristaltic pump design does not have valves that can clog requiring maintenance. Self priming even against maximum line pressure. Bypass valves are not required. Cannot vapor lock or lose primeCommunication Interface. Remote Start/Stop Nonpowered dry contact closure for remote start/stop.. One 48VDC 80mA relay.
