The Versa-Matic E2 2″ (51 mm) bolted metallic air-operated double diaphragm (AODD) pump is designed for demanding industrial fluid-transfer applications requiring durable construction, reliable containment and strong chemical-handling capability. Its bolted design provides a secure seal while maintaining the portability and serviceability expected from an AODD pump.
Metallic configurations are available for different operating requirements, including aluminum, stainless steel and Alloy C options. ATEX-compliant configurations are also available for applications in potentially hazardous environments when installed and grounded according to the manufacturer’s requirements.
| Wetted Material Options | Aluminum, Cast Iron, Stainless Steel and Alloy C, depending on configuration |
| Diaphragm Options | Neoprene, Nitrile, FKM, EPDM, PTFE, Santoprene XL and Hytrel, depending on configuration |
| Construction | Bolted metallic |
