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 .222 on the standard Dia-Vac® Pumps.
Please see How to Specify and Order Pumps at ADI or call the factory direct for more information.
You may also want to reference the Head Connection Diagram page.
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.

* Continuous pressure in excess of 75 PSI should be avoided due to decreased diaphragm and bearing life.
** (See
head connection schematics page)
Notes:
- Test results are averaged, and therefore should be considered approximate.
- Tests performed with 316ss head, Teflon® diaphragm, 3/8 inch diameter hose x 5 ft. line at 75° F, using a std. 1725 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.
