Vacuum pressure pump is a gadget that gets rid of gas molecules from a sealed quantity in order to keep 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 a wide range of operating pressures. Laboratory/filtration vacuum pumps are for use in the laboratory or anywhere a minimal vacuum is needed; typically present both vacuum and pressure capabilities. Use rough vacuum pumps (or roughing pumps) for laboratory and industrial applications requiring a level of vacuum significantly less than 10-3 Torr. Make use of high vacuum pressure pumps if you want vacuums higher than 10-3 Torr. Also, consider the free-air capacity needed (the bigger the free air capability, the faster it will 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 levels, and lower noise, but can contaminate the system and require even more maintenance.
Industrial Vacuum Pumps
Vacuum Pumps
Our selection of industrial vacuum pumps includes oil-less and oil-flooded options. We can customize a pump to suit your specific needs and provide you with guidance when it comes to deciding on the best 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-less rotary vane vacuum pumps designed to operate on a continuous basis at any point from atmospheric pressure to a vacuum degree of 27” HgV (75 torr). These direct drive units are given a higher efficiency TEFC, C-face, 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.
