SHURFLO® 477 SERIES AODD PUMPS
AIR OPERATED DOUBLE DIAPHRAGM PUMP
477 SERIES PUMPS
FEATURES
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.
