New levels of sanitary performance. Long-life engineering features.

For more than half a century, Waukesha Cherry-Burrell has been a leader in the design, manufacturing and application of external circumferential, piston (ECP) style, rotary positive displacement pumps. Waukesha Cherry-Burrell PD pumps are in service around the world in food, dairy, canning, bakery, beverage and pharmaceutical processing, as well as challenging chemical and industrial applications.

Users of Waukesha Cherry-Burrell PD pumps benefit from decades of continuing product improvement. Steady advances in design, metallurgy and fabrication techniques have yielded progressively higher levels of performance and service life.

THE UNIVERSAL II SERIES of pumps is the latest expression of this tradition. They combine 3-way mounting versatility introduced by the Universal with new features that extend pump life and improve sanitary performance. Pump is available in COP or CIPable configurations.

New Sanitation 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.
• Mechanical seals standard. Single or flushed double.
• Seal flush optional: seal areas interconnected to improve circulation and draining of seal flush fluid. Steam-In-Place also is optional.
• Stainless steel bearing frame optional.
• Aseptic ports optional.

Long-life features

• Up to 500 (34.5 bar) psi pressure capability.
• Rotor nut designed for extended service without loosening.
• No bearing in product zone.
• Larger diameter 17-4 PH shafts in seal area 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 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.

Typical product applications

Performance and long lifethrough engineering.

• High pressure capability, up to 500 psi/34.5 bar*, for more demanding jobs.
• Longer service life resulting from fresh engineering approach and high capacity components.
• The right seal for every application, plus interchangeability when needed.
• Metal rotor: Waukesha “88” non-galling alloy, for close running clearance.
• *For higher pressures, consult the factory.

Used with flushing fluid to cool, lubricate, flush away residue. Best arrangement for severe service.

• Single Mechanical Seal*
• Carbon-to-ceramic faces standard. Alternate materials available for abrasive service.

Elastomer choices for “O” rings:

• Buna-N
• Flurocarbon
• EPDM
• Silicone
• Kalrez®
• PTFE Encapsulated

*Mechanical seal material options:

• Carbon
• Ceramic
• Silicon Carbide
• Tungsten Carbide

Universal II Series

Specifications

*For capacities above 450 to 935 GPM, see bulletin FH-1725 on 420/520 UHC (ECP Rotors) and FH-1733 on 420/520 UHCL (Lobe Rotors). **Contact application engineering for higher pressure or higher temperature applications.

Time-tested Waukesha Cherry-Burrell rotary pump; circumferential-piston operating principle

In the Waukesha Cherry-Burrell design, 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.

Exclusive Waukesha Cherry-Burrell design features

For Low Viscosity Fluids, Rotors, made of exclusive Waukesha “88” alloy, can be run with close clearance to the 316 stainless steel fluid head, without 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. As a result, you achieve: high efficiency, good priming ability, metering capability and good flow control.

For High Viscosity Fluids, the large fluid cavities of the rotors ... plus the large, easy entry anti-cavitation ports ... allow efficient pumping of high viscosity fluids, slurries or even liquids with large chunks or particles.

For Non-Lubricating and Abrasive Fluids, the unique Waukesha Cherry-Burrell design has no bearings in the fluid being pumped, no sliding or rolling contact and no rotor-to-rotor contact. This produces MAXIMUM SERVICE LIFE even under severe operating conditions.

Male NPT and 150 lb. flanges optional on Models 006 through 220 size. 150 Ib. flanges standard on Model 320. Contact factory for available rectangular flange inlets.

Engineering

Research, design and application engineers at Waukesha Cherry-Burrell possess extensive backgrounds in their respective fields. You can draw on this experience to solve pumping problems or to counsel on process systems design. The imagination and resourcefulness of our engineers have often helped improve our customers’ profits through production efficiencies.

Testing

Ideas do not remain abstract long at Waukesha Cherry-Burrell. Application of our products to our customer’s specific needs often requires practical testing using real-world parameters. We have a fully equipped and staffed facility for this purpose. For example, the Rheology Laboratory tests applications involving highly viscous fluids.

Sales & Service Network

Waukesha Cherry-Burrell’s trained sales and application engineers are always available for personal consultation to help solve any installation or operational problem. A large number of fully trained Waukesha Cherry-Burrell stocking distributors throughout the country and around the world provide quality Waukesha Cherry-Burrell replacement parts and service.

Quality Control

To maintain the product line’s reputation for quality and to assure that every unit is shipped “ready to install,” each Waukesha pump is thoroughly inspected at every stage of manufacturing and assembly and then tested for design specification. Following the tests, it is disassembled and reinspected before shipment. Waukesha Cherry-Burrell has received ISO 9001 certification.

Metallurgical Control

Waukesha Cherry-Burrell’s reputation for pump reliability under severe operating conditions is directly related to carefully controlled casting production and consistency of metallurgical properties. It is this control that assures castings of uniform analysis that will perform dependably under all operating conditions.
