- Stainless steel pumping tube.
- Low pressure mechanical reversing system for smooth operation.
- Main piston cylinder and both intake and outlet guillotines are driven by a hydraulic power unit.
- Hydraulic intake and discharge guillotines.
- The pump can be installed to start automatically or manually by means of a control panel.
- Easy access to the remote grease lines on top of the pump.
- 16" (406 mm) discharge.
- The Magnum is offered with different features to secure your installation when the top of the reservoir is higher than the top of the barn floor or when you have to manage manure containing sand bedding.
- Performance varies according to installation, manure consistency, quantity and type of bedding - Water addition may be required and straw bedding up to 40 lb per milking cow per day.
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.

The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
