Features

• Up to 500 psi (34.5 bar) pressure capability. 
• Pumps rated to 300°F (149°C) as standard.
• Special rotor nut designed for extended service without loosening
• No bearings in the product zone.
• New shafts are shorter and have larger diameter 17-4 PH shafts:
  • Reduces overhung load which improves shaft alignment and decreases seal and bearing wear for extended seal life.
  • Improves shaft strength and stiffness helping to eliminate vibration
• Heavy duty stainless steel bearing frame standard.
• Double tapered roller bearings.  
• 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.
• Unique mechanical seal design utilizes 2 pin stationary seal and special design shaft for rotary seal
