Air Operated Diaphragm Pump
National Pump & Compressor’s air operated double diaphragm pumps (AODDs) are small and powerful, capable of achieving up to 300 GPM. The high pressure, diesel powered AODDs are non-stalling, non- icing, and lube free. Additionally, the air operated diaphragm pumps are self-priming up to 28’ and can pump thick fluids, sludge, and up to 90% solids. They are a smaller version of our Sludgemast series of pumps which work in similar applications.
National Pump and Compressor offers these intrinsically safe dual-diaphragm pumps in 1”-4” sizes with aluminum, stainless steel, cast iron and polyurethane finishes suitable for any application. These pumps are dynamic, useful for multiple applications on a job site. The flexibility of these pumps helps to eliminate the need for costly motor drives or time consuming size calculations.
