High Pressure Hoses'

33,000-60,000PSI? That's serious business.

You are correct, you need a pulsation dampener to reduce the pulse shock in your system. Without one, you will have components fail as you are well aware.

Without a pulsation dampener, you will be replacing components on a regular basis.

What are you pressure washing at that pressure? Those types of pressure washers are typically only used in large industrial applications, such as heavy equipment cleaning, and bridgework.

We are washing hardened parts. The actual machine design is really cool and functions well. The manufacturer is CESCO (not an endorsement ).

Having worked on an automated pressure wash system (50,000PSI) for about 12 years I wish you luck. We never did master the problem of flexibles snapping off at the fittings or bursting. It just became a fact of life that at least one flexible would have to be changed every 2 weeks or so.

We did come up with one idea, that was to install a second system that we could change over to keep production going. Unfortunately the production manager hit on the idea that if both systems ran together he could speed up the process. Then we were changing at least one pipe every week!

Thanks Guys,

I think at this point I will be getting the pump manufacturer to add the damper. Hopefully this will at least give a little more life to the hoses. Having to live with such short hose life is unacceptable.

I am with ya on increasing the speed from manufacturing, I deal with it on a daily basis. Grrrrr,

This is a bit out of my area but I work on water systems all the time. I'm wondering if you could have a 3-way valve on the trigger. So once you stopped blasting your part the pressure just didn't slam back through the hose. That's my 2 cents worth

The system has a built in relief valve already. The problem does not appear to be when the system shuts down but more so while it is running. The hoses shake rapidly. The hose has never broken in any place other than at the fixed ends. The failure looks like the hose has been pulled out of the compression fitting. Also I should mention that the hoses have what I call a protective outer jacket. I would like to know if anyone else has had any problems with these types of hoses as compared to a hose with no outer jacket.

I agree RV, I am working with the manufacturer on the dampener. The relief valve is only there for as you describe. it is not intended to handle the pulsation. I hope that w can find a resolution soon as the hose cost is killing us!

Thanks for the input!
