CC series – the easy to use CavityComfort progressive cavity pump
The CC series was developed for harsh applications in which long downtimes for service and maintenance work are not acceptable – such as pumping freshly mashed organic suspensions, i.e. highly viscous media loaded with large quantities of fibrous solid matter.
The QuickService design is one-of-a-kind. Vogelsang has managed to decisively improve the tried-and-tested concept of the progressive cavity pump: Compared to conventional progressive cavity pumps, service and maintenance work is significantly quicker and takes up less space, because the innovative QuickService design means there is no need to disassemble parts of the pipe. All essential parts, including the gasket, can be quickly and easily changed, so the pump is soon operational again. Even the mechanical seal in the trusted Quality Cartridge design is easy to replace in the CC series.
At the same time, attention was paid to creating a sturdy and fault-resistant design; features that are essential for biogas plants: The large free passage is ensured over the entire length, preventing clogging and blockages caused by coarse disruptive matter such as foil residue and wood. The sturdy design of the drive line, including the cardan shaft, makes the progressive cavity pumps in the CC series ideal for high dry matter content and media loaded with foreign matter. This means that the unique overall concept of the CC series ensures long service lives, short downtimes for service and maintenance, and low operating costs for your biogas plants.
Features
Options
Progressive cavity pumps are rotating, positive displacement pumps. The basic principle of the progressive cavity pump was invented in 1930 and it is based on a rotor turning in a stationary stator. The rotor is shaped like a feed screw with a large pitch and flight depth and a small core diameter, and it rotates eccentrically in the stator. The stator, in turn, is shaped as a matching but double-threaded internal screw with a double pitch. Due to the geometry and the eccentric rotation of the rotor, cavities form, enclosing the medium and pumping it evenly from the suction side to the discharge side; the second flight of the stator acts as a pumping channel for the medium. Thanks to this pumping concept, progressive cavity pumps feature pumping at stable pressures proportional to the speed. Progressive cavity pumps in the CC series are particularly suitable for abrasive, viscous media such as sludge and organic suspension, even when they contain large quantities of coarse foreign and disruptive matter and/or need to be pumped against a high pressure.
The CC series boasts the innovative QuickService concept, which offers multiple possibilities for replacement of the rotor and stator and for sealing change.
Fast changing of parts
If the pump needs to be operational again as quickly as possible, the stator and rotor are replaced as a single unit. It is also possible to replace the entire rotating unit without dismounting parts of the pipe on either the suction or discharge sides. To do this, simply remove the screws on the angled flange connection and on the pump housing. The unit can then be swiveled upwards or to the side, after which it can be removed and replaced with a new unit. The replaced unit is then reconditioned while the pump is back in service – either by the operator itself or by our service department or one of our pump service partners.
Changing individual components
Alternatively, as with a conventional progressive cavity pump, once the rotor-stator unit has been swiveled out, you can also remove and replace just the stator. If necessary, you can also replace the rotor separately.
Practical sealing change in the CC series
The CC series progressive cavity pumps also offer two options for changing the Quality Cartridge mechanical seal. It can be replaced from the drive end, quickly and completely independently of work on the pumping elements, once the parallel shaft geared motor is removed. Alternatively, the Quality Cartridge can be replaced through the pump housing after the cardan shaft has been removed.
CC44
The small, easy to maintain progressive cavity pump
The CC44 is the Vogelsang progressive cavity pump for small capacities paired with the unique advantages of the Cavity Comfort CC series. Highly viscous sludge, abrasive organic suspension or sewage is pumped efficiently. Thanks to the large free passage, it is not sensitive to foreign matter and disruptive matter. At the same time, it features the easy and quick service typical of the CC series.
