Vacuum Pressure Explained: Absolute Pressure, Gauge Pressure and Units

Absolute pressure uses a perfect vacuum as its zero reference. Gauge pressure uses the surrounding atmospheric pressure as its reference. A negative gauge reading therefore means pressure below the local atmosphere, not negative absolute pressure. Always give both the unit and the reference when specifying a vacuum requirement. Absolute pressure and gauge pressure For a […]

Vacuum Pump Selection: What to Include in Your Inquiry

For a vacuum pump inquiry, provide the process purpose, gas composition, target pressure, required flow with units and measurement conditions, running pattern, possible liquids or dust, installation constraints, and electrical supply. If you are replacing a pump, add its nameplate and a dimensioned installation drawing. Mark unknown information clearly instead of estimating a specification from […]

Rotary Vane vs. Claw vs. Screw Vacuum Pump Selection Guide

Choose a vacuum pump by matching the required operating pressure, pumping speed at that pressure, gas composition and duty cycle. Oil-sealed rotary vane, dry claw and dry screw pumps have different operating requirements. A pump type alone does not establish suitability for moisture, particles, solvents or corrosive gases. Start with pressure, flow and process gas […]
