Chem-Flex Injectors

Hydra-Flex holds patents on chemical dispensing and nozzle technologies. The underlying premise of finding a "better way" to apply fluid handling technologies guides the Hydra-Flex strategy and solutions offerings. They have revolutionized the vehicle washing industry with their venturi design. While the concept of a venturi has been around for over 200 years, Hydra-Flex has taken this design to the next level.

Hydra-Flex created the Chem-Flex Injector to take venturi technology to the next level. Chem-Flex injectors use the most chemically-resistant and longest lasting components available on the market. This includes kynar venturi inserts, stainless steel connections, a hastelloy spring, teflon check ball and Hydra-Flex's exclusive XFC O-ring.

Benefits of Chem-Flex Injectors:

  • Small Footprint - Forget the need for large mixing tanks. Inline installation allows end-users to mount these systems on the wall. Thus maximizing space in every equipment room that Hydra-Flex products call home.

  • Better Vehicle Coverage - Use the same dilution rate but increase delivery pressure. This allows for less solution usage, while at the same time, better coverage.

  • Consistency - Fluctuations in local water pressure do not affect the dilution rate of the injectors. The reason for this is that Hydra-Flex injectors use the pump's regulated pressure. Therefore, you need not worry about this variable. This fact alone results in a greater degree of consistency in your wash system(s).

  • Reliability - Minimize moving parts and, therefore, reduce the potential for failure due to mechanical wear. Chem-Flex injectors will stand up to some of the toughest chemicals on the planet.

  • Precision - Color coded injectors (by flow rate) and metering tips (by dilution ratio) offer precision and easy maintenance of the chemical delivery system.

  • Environmentally Friendly - Since the mixed solution is applied to the vehicle at higher pressure, less solution is needed to clean the same size surface. This often results in substantial reductions in water and chemical usage.

The Nozzles

Hydra-Flex offers five models of nozzles - each nozzle provides a solution for a wide range of industry applications. Hydra-Flex nozzles can be split into two categories - Rotating Turbo Nozzles and Static, Zero-Degree Nozzles.

Rotating Turbo Nozzles

Static, Zero-Degree Nozzles

You absolutely need to consider Hydra-Flex as a viable option whether you're in the market for nozzles or chemical injectors. Top notch quality met with a hungry focus to increase efficiencies for the markets they serve. Hydra-Flex: The Most Trusted Name in Chemical Dispensing.
