Field proven for over 35 years to evacuate dairy manure.
During the siphoning cycle (up stroke) the pressure coming from the hydraulic power unit goes through the reversing valve which redirects it first to the discharge guillotine to close it then, to the intake guillotine to open it and finally, to the main piston to stroke upward and fill the evacuation chamber with manure.
During the evacuation cycle (down stroke) the hydraulic pressure closes the intake guillotine and opens the discharge guillotine. Once both guillotine cylinders have reached the end of their stroke, the pressure reaches the upper part of the main piston cylinder to evacuate manure.

A reliable and versatile system designed to homogenize solid dairy manure and liquid into slurry that can be evacuated through small PVC pipe.
