A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The 1st vacuum pump was created in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.
Vacuum Pumps, pressure pumps, cover a wide selection of operating pressures. Laboratory/filtration vacuum pumps are for use in the laboratory or anywhere a low vacuum is needed; typically present both vacuum and pressure capabilities. Use tough vacuum pumps (or roughing pumps) for laboratory and industrial applications requiring an even of vacuum significantly less than 10-3 Torr. Use high vacuum pressure pumps when you need vacuums greater than 10-3 Torr. Also, consider the free-air capacity needed (the higher the free air capacity, the faster it’ll evacuate the chamber) and whether you will need a lubricated (oiled) or non-lubricated (dry or oilless) pump. Lubricated pumps provide higher capacities, higher vacuum amounts, and lower sound, but can contaminate the system and require even more maintenance.

Our selection of commercial vacuum pumps includes oil-less and oil-flooded choices. We are able to customize a pump to fit your specific needs and provide you with guidance with regards to choosing the right pump for you. You can expect high-quality, long-lasting outcomes when you select Becker vacuum pumps.
100% Oil-less Vacuum Pumps
The Ever-power KVT3.60 – 3.140 series pumps are 100% oil-much less rotary vane vacuum pumps designed to operate on a continuous basis at any point from atmospheric pressure to vacuum pressure level of 27” HgV (75 torr). 
These direct travel units are supplied with a high efficiency TEFC, C-encounter, flange mounted electric electric motor. Each of these pumps is equipped with an integral vacuum comfort valve, a 5μ inlet filter, and vibration isolators as regular equipment.
