Pumps excel in solid-particle handling in the mining industry

The AODD pumps feature the design parameters necessary for pumping larger solids that are found in the mining industry. The pumps are available in two models, a 51mm (2-inch) pump and a 76mm (3-inch) pump. What sets these pumps apart from competitive models is the presence of flap-valve technology, rather than the more traditional ball-valve technology, which allows odd-shaped large solids to pass through the wetted path. The pumps also have a bolted configuration, which ensures total product containment, while a redesigned liquid path reduces internal friction to maximize output and efficiency. The pumps feature the manufacturer’s patent-pending air distribution system (ADS) that greatly improves the performance characteristics of air-operated, double-diaphragm pumps. This air distribution system incorporates three moving parts: The unbalanced air valve spool, the pilot spool, and the main shaft/diaphragm assembly. The ADS results in maximum reliability, lower operational costs and superior flow rates.
