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

The Seko ProMax 4-product venturi dispenser handles up to four chemicals from a single wall unit — select the product on the dial and press the button to fill bottles or buckets fast at 4 GPM. SEKO’s patented hydrodynamic venturi maximizes performance even under lower water pressure, and the Flex-Gap membrane protects your potable supply. Its modular, tool-free design scales up as your operation grows — a strong workhorse for foodservice, hospitality, and janitorial chemical stations.
