Waukesha U22 Lobe pump

• Transferring viscous liquids and slurries in dairies, bakeries, and confectionery production.
• Handling delicate products like fruit pieces, yoghurts, and sauces without damage.
• Metering and dosing ingredients in food and beverage manufacturing processes.
• Circulating brines, oils, and other processing fluids in temperature control systems.
• Unloading tanks and IBCs containing food-grade liquids and semi-solids.

Typical capacity

For this class of equipment, flow rates commonly range from 500 to 20,000 litres per hour, depending on product viscosity and pump speed.

Power supply

Units of this type typically operate on 3-phase industrial power, commonly 400V, 50Hz, with motor sizes varying based on required performance.

Materials of construction

Wetted parts are typically 316L stainless steel for hygiene and corrosion resistance, with food-grade elastomers for seals and O-rings.

Inlet/outlet connections

Commonly found with hygienic connections such as RJT, DIN, or Tri-Clamp, with sizes typically ranging from 38mm to 100mm.

Viscosity handling

Lobe pumps are well-suited for a wide range of viscosities, from thin liquids to highly viscous pastes, often up to 1,000,000 cP.

Temperature range

Typically designed to handle product temperatures from -10°C to +140°C, depending on seal materials and specific model.

Cleaning-in-Place (CIP) compatibility

Most Waukesha lobe pumps are designed for CIP, allowing for efficient automated cleaning without disassembly.

• What is a lobe pump best suited for?

  Lobe pumps excel at handling viscous, shear-sensitive, or particulate-laden fluids due to their gentle pumping action and large pumping chambers. They are commonly used where product integrity is critical.

• Can this pump handle solids?

• What maintenance is typically required for a lobe pump?

• Is a variable speed drive important for a lobe pump?

• What certifications should I look for?

Food processing pumps are valued for reliability and durability in continuous operations. Buyers typically prioritise corrosion resistance, hygiene compliance, and consistent flow rates. When purchasing used units, inspecting seals, impellers and motor condition proves essential. Industry sentiment favours models with straightforward maintenance requirements and availability of spare parts. Stainless steel construction and gentle handling capabilities for delicate products are consistently sought features.
