Almatec CXM Series AODD Pumps for Low- to Middle-Duty Applications

Almatec® CXM Series Air-Operated Double-Diaphragm (AODD) Pumps are general-purpose pumps designed for low- to medium-duty applications and to operate as drum pumps.

Thanks to the pump’s modular design, CXM Series is available with seven different product connections – four sizes with NPT connections and three sizes with BSP connections. The NPT pump sizes 10, 20, 50 and 130 can be changed by rotating the center block. The product connections of the BSP pumps sizes 25, 55 and 135 are located on the face side of the pump. This wide range of product connections allows a precise adjustment of the pump to the specific application.
