  • Heavy duty bearing frame
  • Double tapered roller bearings contribute further to precise rotor movement andlonger seal life
  • Body bolted to gear case to maintain seal face contact, when removing cover androtors
  • Greased lubed bearings for positive lubrication to all bearings over entire speed,temperature and pressure range
  • No bearing in product zone
  • Rotor nuts designed for extended service without loosening
Key Applications

Canning

  • Tomato products
  • Vegetables, diced, slurries
  • Pet foods

 

 

Chemical/Industrial

  • Solvents

MODELS 420-UHC AND 423-UHC

0-400 RPM speed range. 6", 150# flanged port size; suitable to 200 PSI (13.8 bar) differential pressure. Temperature range -40°F (-40°C) to 300°F (149°C).

Double barriers or seals protect at every opening to the pump chamber. Live steam or a sterile fluid is circulated between these double seals at the ports, in the cover and at the shaft seals form an impenetrable barrier to contaminants.
