About Hydro Systems

PSG Dover logo

Hydro Systems was established in 1963 in Cincinnati, Ohio. The company began manufacturing pressure washing equipment, then in 1983 turned its focus to the emerging dilution control market. It has since grown into the world’s largest independent manufacturer of proportioning and dispensing systems for concentrated chemicals.

Today Hydro is a brand of PSG, a Dover company, with manufacturing and distribution facilities across North America, Europe and Asia. Its portfolio includes venturi dispensers, water-driven pumps, peristaltic pumps, central dosing systems, and web and mobile controllers. Hydro focuses exclusively on finding better, more economical ways to dispense chemicals in a controlled, safe and environmentally friendly manner.

Why Choose Hydro Systems?

  • Accurate, Repeatable Dilution. Hydro systems deliver precise chemical-to-water ratios every time, ensuring concentrates perform exactly as designed and removing the guesswork from mixing.
  • Safer Chemical Handling. Automatic dilution reduces direct contact with concentrates, lowering the risk of splashes, spills and exposure for staff working with chemicals.
  • Lower Costs, Less Waste. Correct dilution prevents over-use of expensive concentrates, while shipping and storing concentrates reduces packaging waste and freight costs.
  • Broadest Range Available. From venturi dispensers to peristaltic and water-driven pumps, Hydro offers one of the widest dispensing ranges on the market to suit any application.
  • Improved Productivity. Staff spend their time cleaning rather than measuring and mixing, and training is faster because operators do not need to learn manual mixing ratios.
  • Environmentally Responsible. Accurate dosing prevents chemical over-doses entering drains and waterways, supporting safer and more sustainable cleaning programs.
