B-Series Performance

B-Series Dia-Vac® Performance

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 is 0.160 on the B-Series Dia-Vac® Pump.

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.
