Applications
  • Dairy
  • Food
  • Beverage
  • Home & Personal Care
Standard Design

Robust, durable gearbox design featuring duplex shafts and heavy-duty bearings. Non-galling, twin-wing piston rotors come standard. Increased diameter shafts and optimally positioned bearings minimize the risk of pump head contact. Profiled defined compression elastomers eliminate dead zones, create efficient cleaning, and reduce risk of cross-contamination.
