In biogas plants, many different kinds of liquid media need to be conveyed, possibly after first being extracted from pits and treated. These media generally contain a high proportion of solid matter and fibrous components, as well as disruptive matter such as branches, chunks of hooves etc., and they are normally viscous and laden with foreign matter. These properties and characteristics are problematic for pumping, they lead to damage and malfunctions, and they have a negative impact on the efficiency of the biogas plant.
The BioCut was developed specifically to master challenging pumping tasks. The pump system combines a rotary lobe pump from the VX series and a RotaCut in a special type of construction that makes the overall unit extremely compact in its dimensions. Taking up minimal space, the BioCut acts as the central pump system, ensuring that heavy material like stones and metal parts are reliably separated out of the liquid manure, organic suspension or other fluids. At the same time, the BioCut shreds any disruptive matter in the fluid, such as biomass, and homogenizes the medium, which can then be pumped without difficulty. In addition, this thorough treatment reduces the tendency to form a floating layers and it lowers the viscosity. Indirectly, this results in lower power consumption of the plant, and the improved treatment has a positive effect on the gas yield.
And the system retains the full range of QuickService functions familiar from the VX rotary lobe pumps and the RotaCut: All wear parts can be replaced on site without dismounting the components.
