Auto-Fill Shut Off Overview

Auto-Fill Shut Off Overview
The Compact Dyna-Star Auto-Fill Shut Off fills and refills grease tanks in an automatic lubrication system. As grease
is added to the tank, it pushes the follower plate to the top of the tank where the valve pin actuates and closes the
inlet fluid path.
Note:The remote fill station pump stalls (dead-heads) when the tank is full. If this does not occur, there is a leak in
the system.
Note: The fill pump pressure can be as high as 2000 psi, depending upon the lengths and diameters of Refilling line
(GG) and Supply hose (JJ). Graco recommends using a 36:1 ratio, or higher, air operated fill pump.
