The CC77 is the largest progressive cavity pump available with the innovative QuickService design. The CC77 can pump sludges with a high foreign matter content, abrasive organic suspensions or liquid manure effectively and reliably. The large free passage also makes it extremely resistant to large-sized foreign matter and disruptive matter. At the same time, it features the quick and easy service typical of the CC series, which is not common for progressive cavity pumps of this size.
