The Dynalon 312635 water flow-powered vacuum pump has an anti-backflow check valve for safety and is suitable for siphoning liquid or evacuating gas in a variety of applications. The water supply connects to either a R3/4 or R1/2 threaded hose fitting, or to a 10 to 12mm inside diameter (ID) flexible tube, and requires a 3.5 bar minimum supply pressure. The siphon connects to a 6 to 9mm ID flexible tube and generates up to 16mbar of vacuum. The pump and fittings are made of polypropylene (PP) and the check valve is made of fluoroelastomer (FKM) and polytetrafluoroethylene (PTFE) for chemical resistance and durability.
