M series

The DEPA® M Series Air Operated Diaphragm Pumps are high-performance, versatile pumps designed for a wide range of industrial applications. Constructed from durable materials such as cast aluminum and ductile iron, these pumps are suitable for handling various fluids, including abrasive, viscous, and shear-sensitive media, as well as products with trapped solids. Available in five sizes with standard connections from DN 15 to DN 80, the M Series pumps are compact, lightweight, and ideal for both portable and fixed installations.

These double-acting, positive displacement pumps operate using two alternating pumping chambers driven by compressed air, ensuring efficient and continuous fluid transfer. Key features include maintenance-free control valves, stainless steel base mounts, and the ability to run against a closed discharge, making them suitable for explosive or hazardous areas. The pumps are self-priming, submersible, and capable of handling dry running and harsh usage with minimal maintenance.

The M Series pumps offer easy flow rate control by regulating the air supply and do not require electric motors or special drives. With a modular design, components are interchangeable, allowing for quick and simple internal changes to meet different application needs. The rugged construction and minimal downtime make these pumps a reliable choice for demanding industrial environments.
