Features/Benefits
 
  • Superior hygiene
    Self-draining rotorcase and mechanical seal assembled in the liquid. Low carbon stainless steel with smooth surfaces. Easy to clean – CIP, SIP or by hand, with
    a minimum of entrapped liquid.
  • Easy maintenance
    Front-loaded product seals and robust bearing assembly without shimming.
  • Gentle product handling
    TBi-Wing rotors with small clearances give a smooth flow with little backslip. Able to handle particles
  • Large selection of shaft seals
    Easily interchangeable with other seal types, short downtimes maximum 5 to 10 minutes.
  • Integrated shaft and gear designx
    The complete pump is made in stainless steal.
    The shaft bearings are integrated into the rotorcase. Large shaft diameters and strong bearing design results in small shaft defections and allows to have small clearances inside hydraulic part. The use of duplex steel for the rotors increases wear resistance and improve behaviour on higher temperatures.
