Power for your biogas plant with the pump system CC-Cut
The pump system CC-Cut for biogas applications

Pumping liquid manure, recirculate and organic suspensions is part of the daily work at many biogas plants. However, these media often contain long-fibred solid matter (straw, grass, feed residue), heavy material (metal parts, stones) or disruptive matter (ear tags, branches etc.). This content has a negative impact on the ability to pump the medium, results in increased power consumption of pumps and mixers, and causes malfunctions or even damage, thereby decreasing the cost-effectiveness of a biogas plant.

Vogelsang developed the pump system CC-Cut precisely for these applications. It combines a progressive cavity pump from the CC series with a RotaCut in a compact design. This means that the CC-Cut can be integrated into most biogas plants as the central pump system, without taking up much space. And the CC-Cut also reliably separates heavy material out of highly viscous media, reduces disruptive matter to a manageable size, cuts solid matter and mixes everything intensively. The optimally treated medium is then pumped reliably and trouble-free even against high pressures. In addition, the efficient treatment also reduces the viscosity and the tendency to form floating layers. Both are positively noticeable through a lower energy requirement.

Maintenance and replacing parts are quick and easy with the pump system CC-Cut as they are for the individual components because both retain the full service function: all wear parts can be replaced on site.

Features of the CC-Cut

Separation of stones and metal parts is important for ensuring smooth operation of the cutter itself as well as of the downstream pumps and components, and also to prevent damage and blockages they may cause. Each RotaCut therefore has an integrated heavy material separator.
One key feature of the CC series is its swiveling mechanism, which means that the pipe does not need to be disassembled. The rotor and stator are swiveled upwards or to the side as a single unit.

A generously sized cardan shaft with two cardan joints ensures reliable transmission of the drive power in the CC series from the parallel shaft geared motor to the rotor. A sturdy sleeve – which doesn’t even have to be disassembled when changing the rotor – protects the shaft against solid and fibrous matter and against foreign matter in the medium.

Additional information:
The CC series offers many options for replacing parts. If the pump needs to be operational again quickly, the stator and rotor are replaced as a single unit. It is also possible to replace the entire rotating unit. Alternatively, the stator and rotor can be replaced one after the other, as in conventional progressive cavity pumps.
Vogelsang uses its proprietary software to develop cutting screens with optimized geometry for every size-reduction ratio. For operators, this means the best geometry at all times for smooth running, with minimal wear. The cutting screens are produced from wear-resistant special steel and offer twice the performance since they are reversible.

Options of the CC-Cut

Depending on the model and application, the rotor and stator of the progressive cavity pumps in the CC series are available either in a single-stage standard geometry (M1) or a two-stage standard geometry (M2) for higher pressures. Long geometries (D1) are available specifically for highly viscous, abrasive media.
The hole pattern of the cutting screens, along with the number of cuts, is decisive for the size-reduction ratio. To meet the requirements of every situation, we offer cutting screens for the RotaCut, depending on the size, with free passage from 4 mm to 50 mm. Stainless steel versions are available for aggressive media.

ACCplus further reduces the cost of maintenance and monitoring of the cutter. It monitors the cutting blades status online and displays it on an external display. This means it's no longer necessary to place the cutter out of service and open it to determine the cutting blades status. Additionally, this information can be processed and displayed by the (central) control and/or remote control.
The Auto-Reverse function detects blockages, such as those caused by coarse disruptive matter, and initiates corrective action. By periodically reversing, the function further ensures that a pair of sharp cutting edges is always used while dull ones are sharpened on the opposite site. This delivers optimal cutting performance with reduced power consumption.
