What is the Hydraflex Injection System?

The Hydraflex Injection System is used in our exclusive Detergent POD. The system is used for efficiently mixing and delivering products to the various wash applications.

 

How Does it Work?

When air is applied to the Air Driven Chemical Valve from the Air Solenoid Valve Assembly for POD (see below) it allows water to flow from the manifold (at 200psi) into the top of the Hydraflex Injector. The injector has an orifice inside it that reduces the pressure and this pressure change is what causes vacuum to be created at the detergent injection barb. The detergent then mixes with the water and travels out into the tunnel at 60-80 PSI.

 

Helpful Information: The amount of product used varies based on what size injector is being used and by the metering tip installed. The bigger the metering tip the more product that will flow.

There are different types of Hydraflex Metering Tips, regular Hydraflex metering Tips (P-HFI-219), and Ultra Lean Hydraflex Metering Tips (P-HFI-220)

 

Inside of the Air Driven Chemical Valve is a spring, this spring is rated for 1 million cycles. If this spring were to go bad you would have to replace the whole unit. Some signs that the spring may have broken are, the detergent stays on even after its commanded off. If you have air going into the valve but no chemical comes out this could be another sign of a failed spring. Take caution when removing the cap to inspect the spring it is under tension, also ensure the water is turned off otherwise you will get water backflowing and damage the valve.

 

There are multiple different size injectors be sure if you replace one, that you replace it with the correct size failure to do so could cause excessive chemical use or improper volumetrics.

 

The Hydraflex System works on the change in pressure causing a vacuum so if there is to much back pressure at the application site this could cause a failure to draw chemical.

 

Possible causes of excessive back pressure

~Wrong injector size

~Excessive buildup in the lines or foamers

~Wrong size nozzles
