OEM Diaphragm Replacement Parts for ADI® Pumps 

When it comes to maintaining diaphragm pumps for emissions monitoring and industrial sampling, precision and reliability are non-negotiable. ADIkits offers OEM-quality diaphragm replacement parts built to match the exact specifications of Air Dimensions Inc. (ADI®) pumps. Whether you’re supporting a Continuous Emissions Monitoring System (CEMS) or maintaining portable gas sampling units, we make it easy to find the correct kit and keep your systems running smoothly. 

What Are OEM Diaphragm Replacement Parts? 

OEM diaphragm replacement parts are purpose-built kits used to restore diaphragm pumps to their original operating performance. These kits often include diaphragms, o-rings, gaskets, and fasteners designed for specific pump models to ensure airtight seals and long-lasting operation. 

For industries under strict regulatory oversight—such as power generation, lab analysis, and waste management—using OEM-quality replacement parts is essential. Inferior or generic alternatives can compromise chemical resistance, lead to mechanical failure, and result in inaccurate emissions readings or costly downtime. 

At ADIkits, we manufacture our kits to match OEM standards using proven materials like Teflon®, Viton®, and stainless steel—ensuring durability, compatibility, and peace of mind. 

Designed for ADI® Pumps 

ADIkits replacement parts are engineered specifically for Air Dimensions Inc. (ADI®) diaphragm pumps, including their widely trusted Dia-Vac® models. As a division of Air Dimensions Inc., we have a deep understanding of pump performance and part compatibility—and we use that expertise to manufacture repair kits that meet or exceed OEM expectations. 

We are not a generic supplier. Our kits are the result of more than 50 years of diaphragm pump innovation and U.S.-based manufacturing excellence.
