Description: One pre owned Graco Drum Unloader.
Graco uses a ram to force liquid into the piston pump and this one has a 34/1 ratio so it will do something very viscous.
This one is stainless contact but note the tire seal for the drum ram is rubber.
Graco uses lower downward pressure just enough to force the product into the Graco air powered piston pump and the pump transfers the product to the desired location.
