Micro Diavac Performance

ADI's 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 normal eccentric size is 0.160 on the Micro 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.

Notes:

Test results are averaged, and therefore should be considered approximate.
Tests performed with 316ss head, Teflon^® diaphragm, 1/4 inch diameter hose x 5 ft. line at 75° F, using a std. 3000 rpm motor at 60 Hz.
These test results are for reference only, and are intended to help provide information to the user when determining which pump to buy. Actual pump performance will depend upon the users' applications.
For 50 Hz operation, reduce output by 17%
