Selecting a Suitable Vacuum Pump for Your Rotary

2019-4-4 · When pumps are operated at or close to their minimum pressure, the flow rate will diminish. For example, take the VP18R vacuum pump model with a flow rate of 18 L/min and a minimum pressure of 20 ar. As that minimum pressure is approached, the pump won’t be able to clear 18 L/min.
