The Classic+ Series™ features a stainless-steel casing and rotors that are finished to 3A sanitary standards. The modular design can be easily disassembled for both clean-in-place and clean-out-of-place processes. Cusps in the casing's profile maximize efficiency and draining." This series has timed, non-contacting rotors - which minimize shear while providing extended dry run capability.

One of the most critical parts of any rotary pump is the shaft seal. In part 2 of our 5 part series on seals we take a closer look at Viking Pump's patented O-Pro® seal.
