Determine the specifications of the vacuum pump you need

Vacuum pumps are differentiated by their pumping speed and power, as well as by the method they employ to create a vacuum. Keep in mind that low-flow equates to high vacuum, and high-flow equates to low vacuum. Vacuum power is measured in Pascals (kPa), torr or millimeters of mercury (mm HG), and may be constant or adjustable as needed. Small pumps tend to have higher efficiency; but if your application requires a vacuum pump to run continuously, then make sure the pump you choose is large enough and manufactured for constant use. Otherwise, you'll likely run into overheating.
