MM Series AODD Stainless-Steel Pumps for the Food & Beverage Industry

Almatec® MM Series Air-Operated Double-Diaphragm (AODD) Pumps have been specifically designed to meet the strict standards, regulations and operational requirements that govern the food and beverage industry. MM Series pumps are ideal for these applications because they feature food-grade wetted materials and a construction that enables clean-in-place (CIP) and sanitize-in-place (SIP) capabilities.

The design of MM Series pumps also incorporates soft redirections without rotating parts and shaft seals in the product chamber, a critical consideration for hygienic operations. This design feature, when combined with the pump’s gentle displacement principle, results in a pump solution that is ideally suited for a wide variety of food and beverage applications. MM Series pumps are offered in three pump sizes with different hygienic manifold options.

Features at a Glance

  • Modular design for easier changing of the connections and future technical variations
