Thanks all for looking and avoidance of blasphemy for my crazy brain and methods.
Dutchy Sooner or later I want to do something like this. How heavy (kW) is your vacuum pump? Can you tell us a bit more about which links you need?
I'm no techo so I can only regurgitate the figures I get from my Grabo, From their WEB site, and listed as "the sensor automatically stops the pump on reaching maximum vacuum capacity of 11.6 PSI".
I placed a piece of hardwood on the cup
and toggled through the display on the Grabo screen reporting on the "holding" performance... hopefully they will make sense to you, 162 Kg 374 lb -0.82 bar 11.4 PSI
The vacuum pump system I bought was a BacoEng 5.7L unit which has 7/16-20 threaded connectors on the hose, I am trying to get another hose (emails to manufacturer with no response) so I can attach a Nitto fitting on one end. Not being technical, I'm floundering in the dark.
If your first cut is too short... Take the second cut from the longer end... LBD
