Ultra high pressure (75,000 lbs/in2) apparatus
Pressure is developed in the pressure chamber by a Haskel air-operated fluid pump, with (in this case) silicone oil being used as the pressure transfer medium. Other liquids could be used, but hydrocarbon oil should NEVER be used in this system for two reasons: it might detonate if there is any oxygen present (this is how a diesel engine works), and many hydrocarbon based hydraulic oils become solid at roughly 30,000 pounds/in2.
The pressure system includes a fluid reservoir with filter; pressure gage; air filter, regulator, gage and control valve; and valving to enable chamber pressurization and subsequent liquid return to the fluid reservoir. All high pressure fittings are from Haskel and have appropriate pressure ratings.
Assembly No. DSXHF-903, Serial No. 597-1864, Date Mfg'd 5/97, Nom. Ratio 903 to 1, Max. Press. 150 PSI air 75,000 PSI liquid
We have just reduced the asking price 25% from $12,000 to $9,000 for the ultra-high pressure system shown here, plus $1/mile from Pensacola, Florida, for delivery (Continental US only, please). The system has been used less than 15 hours and works perfectly.
