The new Almatec air-operated diaphragm pump series CXM – shown at Achema 2015 – consists of four sizes and can be equipped with seven different product connections. This is possible thanks to the modular design of the pumps. For each pump of the sizes 20, 50 and 130 two center blocks are available with different connection types and sizes.
This wide range of product connections allows a precise adjustment of the pump to the specific application. This is reinforced by the alternative choice between a ball and cylinder valve system, which can also be converted to each other. Ball valves are ideal for liquids containing particles, cylinder valves for superior suction lift.
Flow optimizations in the product channels ensure high performance and gentle pumping. Almatec CXM pumps are self-priming and proof against dry running. The housings are made of conductive PE, machined from solid blocks, which has a good overall chemical resistance. CXM pumps can be operated within explosion-proof areas and can handle flammable liquids (Atex compliant). The diaphragms used consist of one part only and are designed for a long service life.
The housing parts of the new CXM series are tightened to each other via housing bolts. As usual with Almatec pumps all housing bolts are tightened together against a diaphragm-sized ring per side. This structure transmits the forces of the housing bolts into the housing parts evenly. A consistent flow of forces and an increased bolt torque are the effect of this construction – ultimately increasing pump safety.
