Hygienic rotor lobe pump Rotor selection
![]() | single leaf rotor | used for mediums with particles in large size with low breakage, large pulse, low pressure |
![]() | double leaves rotor | used for mediums with particles, low breakage, small pulse |
![]() | triple leaves rotor | recommend to use this rotor, performance is superior to single leaf rotor and double leaves rotor, smaller pulse than double leaves rotor |
![]() | multi leaves rotor | performance is much stable than the other rotors, while is easy to break the particles |
