Pressure release valve
« on: April 20, 2020, 08:19:09 pm »
I have an old kleenrite edge machine that I am tidying up to use on grotty jobs such as Indian restaurants and fish and chip restaurant.

The pressure release valve is leaking and needs a new piston but in truth I was just going to by pass the valve and run it at a fixed 300psi.

Can anyone point out any problems this may cause with the pump, the machine will get infrequent use.

Many thanks
John

What pump is it?  The release valve on a pump protects the pump. The pump does not know what pressure it is supposed to be producing , it keeps pushing  until something gives,  the relief valve gives at a set pressure before the engine stalls are the motor blows a Fuse

You mean pressure switch on pump
If you bypass it should be ok there only there to protect the pump bushes
I have a prochem comanche  spare machine twin vac 130psi pump i changed the pump and put a one on that didnt have a switch and the only problem I had was changing tools I had to switch the machine off because there was to much pressure going through  to click tools on quickly to change I got a pressure switch fitted there not much but I could fit it myself anyway anyway pressure switch is there ti prolingcthe life of the pump so if your using it as a back up it should  be fine

I think it’s a 300psi induction pump, a lot larger than the 500psi in my ninja

Which does it look like? Only the middle one can run without a pressure release valve ( downloader)

Thanks mike

First one with a blue pump head, bypassed the valve but there was too high an initial build up of pressure, and the pump started to struggle. This machine has a return to the tank and pre heat system through the inline heater to warm the tank before you clean.

By going direct to the outlet ( the female connector where the hose connects caused too much presure
) and by bypassing the presure relief valve and going through the bypass there wasnt enough pressure at the wand tip .

I know a lot of it probably makes no sense but I think the crooks of it is I need to replace the pressure regulator.

First time I have stripped one of these down.
