R-Series High Vacuum Dia-Vac® Pump Hazardous

The R-Series High-Vacuum Dia-Vac® pump is an adaptation of our versatile R-Series Dia-Vac® pump, using valves specifically designed for vacuum applications. This pump is highly customizable and can be modified to work with almost any application.

With an absolute vacuum of -29.8 in Hg, this pump can handle all of your vacuum needs.

ADI’s gas sampling Dia-Vac® Pumps can pass your gas at the speed of need! Due to an increased interest in reducing the pressure, vacuum and/or flow on the Dia-Vac® pumps, our engineers designed a modified eccentric design. This allows you to customize your Dia-Vac® pump to meet your application requirements while at the same time increasing the diaphragm and bearing life. The standard eccentric size for the R-Series Dia-Vac® is 0.222. Please note that the chart below is not meant to be read as a combination of pressure and vacuum at the same time, only pressure or vacuum.
