Hermetically Sealed Oil Mist Eliminators Make The Clear Choice When attached to an effective exhaust line, the hermetically sealed oil mist eliminator prevents corrosive vacuum pump exhaust gases from escaping into the room. It also coalesces oil mist from the pump exhaust and allows it to drain back into the pump. Coalescing the oil mist prevents loss of oil and the frequent need to add expensive vacuum fluids.

Refrigeration Recovery Pump Refrigerant Recovery Efficiency Of 99.8% Continuous discharge pressure to 0 PSIG (. x 05 Pascal) Pump shell rated to 00 PSIG (7.9 x 05 Pascal) Minimal loss of pumping efficiency below 9.9 inches Hg, (,000 microns Hg, Torr, mbar) CRR-A CAPTURE Pump The CAPTURE pump has been specifically designed for recovery and recycling systems that evacuate refrigerant systems to greater than 9.9 inches Hg( Torr, mbar) and boost refrigerant vapor to a holding tank. The recovery and recycling systems employing a CAPTURE pump are built for evacuation of R-, R- and R- chillers. The pump design has been in use in recovery and recycling systems for over 5 years. Pump oil separation and return is accomplished by attaching a standard float actuated oil return found in refrigerators. The oil separator is a proven technology that minimizes pump oil loss even for very large refrigerant systems. DUOSEAL pump oil, cat. no. 407K-, is recommended fluid to operate the CAPTURE pump.

Foreline Trap Selection Foreline Traps For protection against contaminants in vacuum systems Foreline traps are used to prevent harmful substances generated or resident in vacuum systems from damaging vacuum pumps. Particulates can become lodged in a pump mechanism causing physical damage. Vapors can condense to liquids within the vacuum pump as a natural result of gas compression. Liquid water, solvents and acids can cause serious damage to a vacuum pump mechanism. (Refer to CHEMSTAR, pages 6 and 7 for work with corrosive gases). Foreline traps are also used to prevent oil backstreaming, the migration of oil molecules from vacuum pumps back into vacuum systems causing contamination of those systems. This is more likely to occur at vacuum levels of x 0 Torr (. x 0 mbar) or deeper that are maintained continuously over long periods of time.

Examples: paraffins, solvents, organic acids, alcohols. Application Note for Cold Traps Cold traps employing a dry ice slurry or liquid nitrogen are effective as long as the refrigerant level is maintained. If the trap warms up while the pump is running, all of the trapped condensables will be ingested by the vacuum pump, contaminating the oil. Cold traps must be cleaned out at the end of each day. If the pump is run overnight, the trapped condensables will ultimately be ingested by the pump as the trap warms up. Cleaning a Dry Ice Slurry/Liquid Nitrogen trap is easy. The steps are:. Turn off the pump;. Leak air into the trap;. Remove the center well and plexiglass ring to a hood. The center well can be washed off into a beaker or the condensables can be allowed to evaporate in the hood. 6

Vacuum Pump Oils & Oil Change System Gold Vacuum Pump Oil Exceptionally low vapor pressure High stability in chemical environments No additives or inhibitors Recommended for Welch belt-drive and direct-drive pumps A double distilled synthetic hydrocarbon oil designed for excellent resistance when pumping corrosive gases or vapors. A synthetic base stock that has no aromatic compounds or sulfur which accelerate varnishing, sludging and carbon build-up when pumps are used to pump corrosives. Gold oil will give a longer service life and superior protection for the internal metal components of a pump in corrosive pumping applications compared to DUOSEAL and Premium Oil. Gold Oil offers excellent vacuum pressure in both belt-driven and direct-driven vacuum pumps over time. Gold Oil is miscible with conventional hydrocarbon oils and can be used without rebuilding the pump. The oil is clear and colorless. CAT.

The hydrotreating virtually eliminates aromatics and sulfur to give good resistance to sludge and varnish formation overtime in corrosive environments. Premium enables direct-drive vacuum pumps to maintain the highest vacuum performance over time. The oil is light yellow. CAT.
