Seko ProMax 4-Product Wall-Mount Venturi Chemical Dilution Dispenser – Button, Flex Gap, 1 GPM

The Seko ProMax 4-product venturi dispenser dilutes and dispenses up to four different chemicals from one compact wall unit — turn the dial to select the product and press the button to fill. Running at 1 GPM, it allows the finest flow-rate control for precise dosing, while a Flex-Gap membrane protects the potable water supply. Built on SEKO’s patented hydrodynamic technology with a modular, tool-free design, it is ideal for rooms that cycle through multiple cleaners.
