The Hydraulic Sample Extruder ejects undisturbed soil samples from full size thin-walled samplers (Shelby Tubes) in one stroke. The bench-top extruder is set up for 3in (76mm) diameter tubes of 30in or 36in (762mm or 914mm) length, but can also process 2in (51mm) diameter tubes with the optional HMA-282 adapter. The smooth, easily controlled piston stroke permits easy handling and rapid processing of samples.
Up to 5,600lbf (24.9kN) of force can be used to eject even stubborn samples. The hydraulic system precisely controls the horizontally mounted piston. The HM-524 Extruder comes with a sample receiving trough (not shown) to insure minimal disturbance when ejecting and logging sample. The 1.7gpm (6.4lpm) hydraulic pump is powered by a 1hp electric motor. Hydraulic oil reservoir has 2.5gal (47L) capacity.
