CC-Cut - powerful components – perfectly combined and coordinated
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 current consumption in pumps and mixers, and causes malfunctions or even damage, thereby decreasing the cost-effectiveness of a biogas plant.
Vogelsang developed the CC-Cut pump system 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, shreds 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 a floating crust. Both these advantages can be seen in the lower input energy requirement.
Maintenance and replacing parts are quick and easy with the CC-Cut as they are for the individual components because both retain the full service function: all wear parts can be replaced on site.
The combination of a progressive cavity pump from the CC series and a special RotaCut make the CC-Cut pump system an efficient solution when it comes to pumping heterogeneous and highly viscous media loaded with heavy material and disruptive matter, cost-effectively and reliably against high pressures. In the first step, harmful foreign matter such as stones and metal parts is separated out in the RotaCut due to size or weight; this matter can later be disposed of through a cleaning port during maintenance.
Light disruptive matter and solid matter, such as wood, fibers etc. are drawn along in the flow of fluid to the cutting screen, where they are shredded and mixed with the fluid. In this way, the CC-Cut pump system converts a heterogeneous, difficult-to-pump medium into a pumpable, homogeneous suspension, which is routed directly into the suction housing of the progressive cavity pump.
The pumping principle of the CC progressive cavity pump
The pumping principle of the rotating, positive displacement pumps is based on two key components: the rotor, and the fixed stator in which it rotates. The rotor is shaped like a feed screw, with a large pitch and flight depth and a small core diameter. In addition, the rotor rotates “eccentrically” in the stator. The stator, in turn, is shaped as a matching but double-threaded internal screw with a double pitch. The interaction between the sophisticated geometry of the pumping elements and the eccentric rotation results in cavities that enclose the medium, which is pumped evenly from the suction side to the discharge side. In addition, the delivery rate is speed-dependent, which means that the progressive cavity pump is very easy to regulate. Furthermore, the progressive cavity pump can generate strong suction, thanks to its underlying principle. The CC-Cut benefits from all these advantages and the CC series ensures reliable and cost-effective pumping of the previously treated medium.
When developing our compact pump systems, we at Vogelsang pay particular attention to day-to-day handling and easy maintainability. In line with this, the design of the CC-Cut ensures that the service functions of the CC series progressive cavity pumps and the RotaCut are not impaired in the overall system. It features the quick opening function that is typical of the RotaCut, giving free access to the cutters. To remove the blade rotor, you simply have to dismount the adjustment unit. Then, you can either turn the cutting screen around or replace it and, if necessary, renew the gasket.
Service and maintenance of the CC-series progressive cavity pump are just as easy. Thanks to the innovative QuickService concept, there is no need to dismount parts from the pipe. The rotor and stator swivel out as a unit and can then either be replaced as a unit or renewed individually.
The two components can both be maintained quickly on site, allowing the CC-Cut pump system to be put back into operation after a very short time. There is no need to dismount the pipe. This reduces downtime to a minimum.
CC-Cut / RCQ43Qpro
The compact, easy-to-maintain pump system for intensive preparation
The CC-Cut systems, based on the RotaCut RCQ-43Gpro, provide intensive preparation of viscous media, while at the same time ensuring rapid maintenance and quick and easy on-site part replacement. Disruptive and foreign matter is reliably macerated and heavy material is separated out, reliably preventing problems and malfunctions in downstream process stages.
