SHURFLO® 477 Series AODD Air Operated Double Diaphragm Pump

The SHURFLO Model 477 Air Operated Double Diaphragm Pump was developed for chemical transfer, injection and spraying applications. This AODD pump features a directional control spool design that eliminates the stalling problems associated with over center directional control designs. With an open flow capacity of up to 10 gpm, the SHURFLO Model 477 pump will easily handle your current lower 5 gpm open flow applications, and will also apply to many applications currently using a 14 gpm open flow pump.

Industry standard fittings and mounting footprint make the installation of the SHURFLO Model 477 pump in existing equipment very simple. A 1/4” barb air connector and 1/2” and 3/4” barb liquid connectors are included.
