The 5-Way Push Lever Mixing Station is an ASSE 1055 certified chemical proportioner that accurately dilutes chemicals to the required ratios and dispenses into any size container. This venturi injection system uses city water pressure (25 - 125 PSI) to draw and blend chemical concentrate into the water stream and precision metering tips to set the dilution ratio for each lever. Push Lever Mixing Stations require the user to push and hold the lever to dispense. Choose a factory-set flow rate for each lever at the time of order (Bottle Fill, Low Flow, High Flow).
