Waukesha Rotary Positive Displacement Pump Universal II

The Universal 2 Series Pumps is the latest expression of this tradition. They combine 3-way mounting versatility introduced by the Universal 1 with new features that extend pump life and improve sanitary performance. Pump is available in CIP-able configurations.


Sanitary Features :
• CIP capability available. Pump body has optional internal flat body profile and will free drain with vertical ports. Optional rotor and body hub drilling provided for difficult CIP cleaning applications.
• Cover is free draining in horizontal or vertical port positions.
• Rotor/shaft connection sealed from product zone.
• Single mechanical seals standard. Optional double mechanical seals also available.

Long-life Features :
• Up to 500 psi (34.5 bar) pressure capability.
• Special rotor nut designed for extended service without loosening.
• No bearings in the product zone.
• Larger diameter 17-4 PH shafts for greater strength and stiffness. Helps eliminate vibration; extends seal life.
• Heavy duty bearing frame (stainless steel available as an option).
• 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.
• O-Ring on inner seal, seals on clean surface as seal moves due to wear.
