For sale is a Hydraulics International 3G-SS-20-0, s/n 0503020 with high pressure brass quick disconnect fittings, male on the inlet and female on the outlet and a BC-type quick disconnect on the drive port.
Whips are as follows:
Upper left: Oxygen with handwheel and QD to inlet side of booster, analog pressure gauge.
Upper right: DIN with handwheel and QD to inlet side of booster, no pressure gauge.
Lower left: DIN with QD to outlet side of booster, analog pressure gauge, needle valve and check valve.
Lower right: Wrench type oxygen fitting on one end, and an NPT female with an NPT double male threaded into it on the other end.
The square plastic bag has o-rings for the drive side of the booster.
Also in the photo are some miscellaneous brass and SS NPT fittings. The long part upper right of the rest is a check valve, and to its left in the small plastic bag is a flow restrictor (small orifice, like found on an HP hose for SPG).
I think I have a hardcopy manual somewhere ... and probably a PDF. I believe that the manual can be downloaded from the HI website.
The booster had just been serviced (including O2 cleaning) by HI when I acquired it. Its seen only light use since, filling rebreather bottles.
I'd prefer to sell this as a package. Asking $1500 for the lot, plus shipping. Payment via PayPal accepted. I'm located in Gainesville FL and pick-up here in exchange for cash works too.
Thanks for looking.
