Magnum - Single Piston Pump

Field proven for over 35 years to evacuate dairy manure.

The Magnum is a low power pump that transfers efficiently thick manure from tied stall barn or from free stall barn up to your main storage through underground line. Different configurations of hopper inlet are offered to suit 1 or 2 barn cleaner installations and alley scraped by a skid-steer loader. The Magnum comes with different discharge choices depending on the installation and the type of bedding. The heavy hydraulic guillotine valves with sharp edges are specifically designed to handle thick manure containing straw and sawdust. A specific version is also offered to manage sand bedding.

Working Principle

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.
