This foam pump is designed for pumping all types of detergent, with the exception of acid. The pump is fitted on a mixing tank of acid-proof steel and a Hydro Minder mixing valve. Ideal for pumping detergents through hose/hose reel to high-pressure gun with foam lance. The pump can be fitted with a timer function that stops after the set time, or connected to a separate control cabinet/token dispenser. The Hydro Minder mixing valve is fitted directly on the mixing vessel. The mixing vessel mixes the right ratio of water/detergent to ensure that the pump always has the right ratio for the liquid being pumped. The mixing ratio is adjustable between 1:1 and 1:100 by switching to different coloured adapters included in the kit. Maintains a constant level of pre-mixed liquid via adjustable float and valve.
