Pumps pass large solids easily
Flap valves prevent damage from product entrapment and settling of solids in intermittent-duty applications.
Wilden Pump and Engineering’s Brahma advanced metal AODD pump powered by the energy-efficient Pro-Flo SHIFT Air Distribution System (ADS) handle the passage of large solids in tough applications.
The bolted metal pumps incorporate flap valves and a unique top inlet with bottom discharge orientation capable of passing solids up to 76 mm in diameter, while preventing damage from product entrapment and settling of solids in intermittent-duty applications.
Brahma pumps are also equipped with Wilden’s Pro-Flo SHIFT ADS, which incorporates an air control spool. It automatically restricts the amount of air going into the pump during the latter part of each stroke to eliminate over-filling in the air chamber, and it reduces air consumption, which cuts energy use and operating costs.
The pump manufacturer based in Grand Terrace, Calif., claims AODDs achieve up to 60% savings over competitive technologies and handle harsh operating environments.
The AODDs, made from aluminum or ductile iron, are available in two sizes (PS810-51 mm and PS1510-76 mm).They’re submersible, self-priming and shear-sensitive. Pressure handling capabilities are up to 125 psig.
Maximum flow rates are 640 lpm (169 gpm) for the PS810 and 882 lpm (233 gpm) for the PS1510. Diaphragms are available in Buna-N and Neoprene.
