ARO 666320-EEB-C Compatible 3″ Aluminum Air-Operated Diaphragm Pump

With its 3" BSP connection and aluminum housing, it is one of the models in the series with the highest flow rate. With a flow capacity of 897 liters per minute and a maximum operating pressure of 8.3 bar, it is used for large-scale tank emptying, pool drainage, and high-volume line feeding applications. The use of Santoprene throughout the seat, ball, and diaphragm ensures high fatigue resistance when handling fluids containing abrasive solids; Since it can handle solid particles up to 9.5 mm in size, the risk of clogging is low in lines containing sludge, sediment, and suspensions. The liquid end and manifold are made of aluminum, and the connection hardware is made of carbon steel; this combination offers an economical and sufficiently durable design for large-body pumps. A wide operating range from -40 to +177 °C allows for use with both chilled and heated process fluids. The measured sound level is 86.3 dB(A); a silencer or enclosure is recommended for indoor use.
