Waukesha Universal 2 Sanitary PD Pump 

Overview 

The Waukesha Cherry-Burrell Universal 2 Positive Displacement Pump takes the "Can Do" Universal 1 pump to the next level. Featuring advanced sanitation technology, the Universal 2 also has improved performance features, enabling longer pump life and installation flexibility. Versatile in application, the Waukesha Universal 2 Pump is among the most reliable in the industry.

Features

Univeral 2 Pump Features include: 

• CIP capability available. Optional flat body profile enables free draining when vertically ported. Rotors and body hub can also be drilled for difficult CIP cleaning applications.

• Cover is free draining in the horizontal or vertical position.
• Rotor/shaft connnection sealed from product zone. 
• Single mechanical seal standard. Optional double mechanical seals also available. 
• Seal flush optional: seal areas interconnected to improve circulation and draining of seal flush fluid. Steam-in-place is also optional. 
• Stainless steel bearing frame optional on models 006-370
• Aseptic Design Options  

Univeral 2 Pump Long Life Features include: 

• Up to 500 PSI (34.5 bar) pressure capability 

• Special rotor nut designed for extended service without loosening
• No bearing in the product zone
• Large diameter 17-4 PH shafts for greater strength and stiffness. Helps reduce vibration; extends seal life 
• Heavy duty beariing frame (stainless steel available as an option)
• Double tapered roller bearings 
• Greased lubed bearings for positive lubrication to all vearings 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
• Unique mechanical seal design utilizes 3 pin stationary seal and special design shaft for rotary seal 

Theory of Operation

The Waukesha Universal Series of pumps use the time-tested circumferential-piston operating principle. The arc-shaped "pistons" (rotor wings) travel in annular-shaped cylinders machined in the pump body; the resulting long sealing path reduces slippage and produces a smooth flow of product without destructive pulses or pressure peaks and without valves or complex parts.

Because the rotors are made of Waukesha non-galling Alloy 88, the rotors can be run with exceptionally close clearance with the 316L stainless steel fluid head, without having to fear galling or seizing should inadvertent pressure surges cause contact. The close clearances combined with the rotor geometry, which gives a long sealing path between the pump inlet and outlet, means low slip operation even with low viscosity fluids. This means you get high efficiency, good priming ability, metering capability, and flow control everytime you use a Waukesha Universal Pump. 

Additionally, because of the large fluid cavities in the rotors, plus the large, easy entry anti-cavitation ports, the Universal Series of pumps allow efficient pumping of high viscosity fluids, slurries, or even liquids with large chunks or particles. 

 

Finally, because the Waukesha Cherry-Burrell design has no bearings in the fluid being pumped, no sliding or rolling contact and no rotor-to-rotor contact, we get excellent service with every Universal Positive Displacement pump even under sever or abrasive conditions.
