A vacuum pump is a device that removes gas molecules from a sealed quantity in order to leave behind a partial vacuum. The first vacuum pump was developed in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.
Vacuum Pumps, pressure pumps, cover an array of operating pressures. Laboratory/filtration vacuum pumps are for use in the lab or anywhere a minimal vacuum is necessary; typically give both vacuum and pressure features. Use tough vacuum pumps (or roughing pumps) for laboratory and industrial applications requiring an even of vacuum significantly less than 10-3 Torr. Make use of high vacuum pressure pumps when you need vacuums higher than 10-3 Torr. Also, consider the free-air capacity needed (the bigger 
the free air capacity, the faster it will evacuate the chamber) and whether you need a lubricated (oiled) or non-lubricated (dry or oilless) pump. Lubricated pumps provide higher capacities, higher vacuum amounts, and lower noise, but can contaminate the system and require more maintenance.

100% Oil-less Vacuum Pumps
The Ever-power KVT3.60 – 3.140 series pumps are 100% oil-less rotary vane vacuum pumps made to operate on a continuous basis at any point from atmospheric pressure to a vacuum level of 27” HgV (75 torr). These direct travel units are supplied with a higher efficiency TEFC, C-encounter, flange mounted electric motor. Each of these pumps is equipped with an integral vacuum alleviation valve, a 5μ inlet filtration system, and vibration isolators as regular equipment.
