The CC66 is the powerful, user friendly and easy to maintain progressive cavity pump of the CC series. It comes into use, when media are highly viscous or abrasive as well as contain a high amount of foreign matter, which have to pumped with a high capacity and against high pressures. At the same time no long downtimes due to service and maintenance are acceptable. This can apply to e.g. the dosing of solid matter at biogas plants or the pumping of highly viscous sludges at wastewater treatment plants. For those applications the CC66 is the right choice.
