Working Flow Rate: How to Compare Vacuum Pumps .

Working Flow Rate: How to Compare Vacuum Pumps .

Often overlooked in selecting a vacuum pump, however, is the importance of flow rate (also called pumping speed or air displacement) in matching a vacuum pump to an application. A pump's flow rate is simply the volume of gas or vapor it can move per unit of time, with units variously reported as liters per minute (lpm), cubic feet per minute .

Tech: How External Vacuum Pumps Free Up Horsepower

The correct pump is sized and operated at the desired speed to accomplish that goal. As a rule that means using a pump with enough air flow capacity and a vacuum control valve to maintain the desired amount of vacuum. If the pump begins to exceed the desired vacuum level, the control valve provides an adjustable air leak to prevent it.
