Almatec AODD Pumps MM Series

 

Almatec Maschinenbau GmbH is a premium manufacturer of air-operated double-diaphragm (AODD) pumps and a company which has successfully combined a worldwide presence with proximity to the end-user.

 

The MM Series air-operated double-diaphragm (AODD) pumps have specifically been designed to meet the strict standards, regulations and operational requirements that govern the food and beverage industry thanks to their use of food-grade wetted materials and a construction that provides easy cleaning.  The pump design is reflected in the name “MM”, as it refers to “modular metal”. The modularity allows to easily exchanging the connection pieces to the standard the customer requires – a frequent topic in hygienic applications.

The MM Series’ housing is made from stainless steel 1.4404 (SS316L) and the pump’s wetted surfaces are available with a surface roughness of max. 3.2 µm. An optional version with a surface roughness of 0.8 µm is also available. The MM Series’ materials and design enable clean-in-place (CIP) and sanitize-in-place (SIP) capability. All the pump’s materials comply with the hygienic standards of the FDA, and pumps equipped with PTFE diaphragms and ball valves also comply with EC1935/2004. In addition, the pumps are ATEX conforming according to the 2014/34/EU directive.

 

The pump is also available with different hygienic manifold options. Inlet and outlet orientation can easily be adjusted between “U-Shape” (inlet and outlet on the same side) and “Z-Shape” (inlet and outlet at opposite side). The connection options are:

 

Code A1:              Screwed aseptic pipe connection (DIN 11864-1)

Code A2:              Aseptic flange (DIN 11864-2)

Code A3:              Aseptic clamp pipe connection (DIN 11864-3)

Code M:               Milk pipe connection (DIN 11851)

Code T:                 Tri-Clamp connection (DIN 32676)

Code S:                 Open butt-welding end (small and easy to adapt)

 

The three pump sizes – MM 15, MM 25 and MM 40 – achieve maximum capacities of 3.5 / 9.2 / 20 m³/h (15.4 / 40 / 88 gpm) resp., maximum discharge pressure up to 7 bar (100 psig) and a short-term temperature range up to 130 °C (266 °F) for cleaning processes.

 

 

 

Applications:

 

Transfer and filling of beverages, sauces, toppings etc.

Dosing of food and beverage ingredients

Processing of meat, pastry and dough, smoothies, fruit pulp, candies
