R-Series Dia-Vac® Pump Heated Head Hazardous Area
Product Description
R-Series explosion-proof Dia-Vac® pumps are used worldwide in hazardous atmospheres within the petroleum, refinery, chemical, utility and pharmaceutical industries. These durable, leak-free diaphragm gaseous sampling pumps are also an ideal choice for OEM customers and can be custom designed and built for your specific application.
The heads of this explosion proof pump can be heated using plant steam, ensuring that that gas temperature remains above the dew point.

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.
