HyVac® Vacuum Pump Oil is a high quality, high boiling range, straight mineral oil of approximately 350 SUS at 100° F. Refined from specially selected mid-continent solvent refined paraffinic crude oils. Its low vapor pressure and other unique characteristics make it especially suitable for use in most high vacuum pumps including Welch, Precision and all HyVac Pumps.

HyVac Flushing Oil is for use in cleaning out mechanical vacuum pumps of contaminants between oil changes. Used on a regular basis, Flushing Oil helps keep pumps running clean and allows for minimal contamination of new pump oil when it is introduced to the pump. Do NOT use flushing oil for vacuum operation.

The HyVac® 1 vacuum pumps are small, reliable, 2-stage pumps capable of about 0.3 micron vacuum pressure, rated at 10 Liter / minute free air displacement. Excellent small capacity pump, complete with exhaust dome and baffle to condense oil spray and prevent smoking. Supplied complete with ¼ HP, 115V, 60Hz motor, pulleys and v-belt, oil level sight gauge, draincock and nipples. 3-wire cord and plug with integral switch and belt guard included.

The HyVac® 2 vacuum pump is a larger, reliable, 2-stage pump rated at 25 Liter/minute free air displacement and an ultimate vacuum of 0.1 micron. Reaches 6-12 militors of mercury with gas ballast open to atmosphere and, with gas ballast closed, recovers to original vacuum in 2-5 minutes. Gas ballast enables rapid purging of pump oil. Complete with exhaust dome and baffle to condense oil spray and prevent smoking. Supplied with ¼ HP, 115V, 60Hz motor, pulleys and v-belt, oil level sight gauge, draincock and nipples. 3-wire cord and plug with integral switch, belt guard and gas ballast included.
