Piston Vacuum Pumps

A Piston vacuum pump generates vacuum through the workings of a piston. We have written several in depth articles on the Piston Pump at: “Piston Vacuum Pump: The Ultimate Guide to WOB-L and ROC-R Vacuum Pumps” and “Selecting a Proper Vacuum Pump for your Acrylic Vacuum Chamber”

The main advantages of a piston pump are oil free operation, maintenance free, and no oil mist emission. This means that the vacuum pump is very popular in laboratory settings and indoor environments.
