1/2" Air-Operated Double Diaphragm Pumps

Versa-Matic® E5 1/2" Air-Operated Double Diaphragm Pump (AODD)

Product Overview

The Versa-Matic® E5 1/2" Air-Operated Double Diaphragm Pump is a compact, highly versatile pumping solution designed for chemical transfer, metering, dosing, fluid handling, and industrial process applications. With flow rates up to 11 GPM (53 LPM), dry suction lift up to 12 ft (3.6 m), and a leak-free bolted construction, the E5 delivers reliable performance while minimizing maintenance requirements.

Available in both metallic and non-metallic configurations, the Versa-Matic E5 can be optimized for a wide range of aggressive chemicals, solvents, oils, and process fluids. Non-metallic versions are available in Polypropylene, PVDF, Acetal, and Conductive Polypropylene, while metallic models are offered in Aluminum, Stainless Steel 316, and Alloy C.

At the heart of the E5 is Versa-Matic's exclusive Elima-Matic® Shoe Valve Air Distribution System, providing reliable On/Off/On operation, outstanding air efficiency, and resistance to freezing or air blow-by issues commonly associated with conventional diaphragm pumps. The rugged bolted construction ensures superior sealing performance, especially when transferring low-viscosity or thin liquids.
