Long-life features

 

Precision rotor movement virtually eliminates vibration; extends seal life.

 

• Rotor nut designed for extended service without loosening.

 

• No bearing in product zone.

 

• Larger diameter shafts in seal area for greater strength and stiffness.

 

• Heavy duty bearing frame (stainless steel available as an option)

 

• Double tapered roller bearings on all models. Contribute further to precise rotor movement and longer seal life.

 

• Greased lubed bearings for positive lubrication to all bearings over entire speed, temperature and pressure range.

 

• Body retaining screws for maintaining mechanical seal contact during inspection.

 

• Extended outer seal life. A wave spring, instead of an O-ring, mechanically loads the seal.

 

• O-Ring on inner seal, seals on clean surface as seal moves due to wear.

 

• 3 full-radius drive pin grooves reduce stress/increase durability of seals.
