Rotary vane vacuum pumps have been the mainstay for the industrial and scientific vacuum user for many years. They are proven designs that are used in a wide variety of applications. They are available in 4 variations, each having a distinct optimum operating pressure region and application suitability. Please consult your nearest AVT Services representative for specific application information.
Single stage dry vane rough vacuum 1000 to 150 mbar
Dry vane vacuum pumps, also known as carbon vane, are only suitable for dry applications. Vacuum systems which involve moisture are not suitable. These pumps are excellent for use in all dry applications from atmosphere down to their ultimate. They are characterized by generally running hotter, and are also noisier than oil sealed pumps. They are available in sizes from 3m3/hr through to 130m3/hr.
Single stage oil sealed rough vacuum 1000 to 1 mbar
Single stage oil sealed rough vacuum pumps are the mainstay of the general industrial vacuum market. They are characterized by being compact, ruggedly built, with air cooling in sizes ranging from 3m3/hr to 1300m3/hr capacity. A wide variety of inlet and exhaust accessories are available to optimize these pumps for specific applications.
Single stage oil sealed high vacuum 100 to 10-2mbar
Oil sealed single stage high vacuum pumpshave closer tolerances and better vacuum distilled sealing/lubricating oils for use in the lower pressure regions which the rough vacuum pumps cannot get to. They are suitable for continuous operation from 100mbar through to their ultimate vacuum. A wide range of inlet accessories and oils are available to optimize the pump for many scientific and industrial applications, and they are available in sizes from 18m3/hr to 275m3/hr capacity.
Two stage oil sealed high vacuum 10-1 to 10-4 mbar
A second stage added to the single stage pump allows it to produce vacuum down to 10-4mbar. They are seen in most laboratories in both instruments such as GCMS, and on the bench tops providing vacuum for distillation, evaporation and other drying procedures.They are available in capacities from 1.5m3/hr to 275m3/hr, and have a wide variety of accessories available.
