P38A EAS question

[pwood999]

Tervitused
Ei hakka uut teemat alustama, nimelt EAS-pump lülitub sisse 200 psi juures ja välja 240 psi juures.
Kas see tundus nagu palju?



P38Is the pump operation regulated by the green sensor under the block?

Yes. Test it first if you can. They are available, but make sure it's the closed above 140psi type. Many are the other way round.

I'm guessing you're Estonian ? Put your town name or local region in your profile !!

Thanks for the quick response.
I'll start looking.

Not sure what the valve block seals will handle, but if it really if getting that high, check the pressure relief valve. It should blow off above 180psi.

Every time I've tested... maybe on 3 different green pressure valves, they've stopped the compressor at 150psi on the dot.

I'd have thought the compressor itself would have given up the ghost by 200psi!

I don't know how accurate my pressure guage is though.

 

[pwood999]

+1 on the compressor limit. Even with a gauge directly on the pump outlet, I've never seen more than 190psi. Hence why I asked if it was definitely a P38.

Definitely P38 and 2001
I started to doubt the pressure gauges but I went to the guy and checked, everything is correct. This explains why the pump had to be repaired so often. In the end, I put a non-original ring on the pump, which I took from a small compressor and seems more durable. The block was recently renovated. The overpressure valve has not started working.

Definitely needs more investigation. You must be the only one with a P39 EAs pump that can produce that much pressure.

P39?

 

[Grrrrrr]

P39?

Like a P38A but everything is a little higher.
