Hygienic and sanitary pumps are engineered to minimize contamination risks, support clean-in-place or sterilize-in-place protocols, and handle sensitive or regulated products without compromising quality. These pumps appear most often in environments where even minor residue or bacterial growth can create serious issues, such as dairy processing, nutraceutical production, or pharmaceutical manufacturing.
The design priorities typically include smooth internal surfaces, minimal dead legs, easy drainage, and materials that resist corrosion while standing up to rigorous cleaning cycles. When these elements work together, facilities can maintain product safety, reduce downtime between batches, and meet the expectations of regulatory bodies and customers alike.
Rotary lobe pumps move fluid by trapping a fixed volume between rotating lobes and the pump casing. The lobes turn in opposite directions without touching each other, synchronized by external timing gears. This non-contacting action creates gentle handling, low shear, and minimal pulsation - qualities that matter when product integrity is non-negotiable.
Because the pumping elements stay out of the fluid path in many configurations, these pumps manage a wide range of viscosities and can pass soft solids without damaging either the pump or the product. Many models also support full clean-in-place and sterilize-in-place cycles, which reduces the need for complete disassembly during sanitation.
For processes that involve delicate emulsions, chunky mixtures, or ingredients that degrade under high shear, rotary lobe technology often provides the balance of efficiency and product protection that other positive displacement designs struggle to match. If your application requires both hygienic performance and gentle transfer, this category deserves close consideration.

Viking Pump’s hygienic offerings continue the legacy of Wright Flow Technologies with refined engineering focused on cleanability, durability, and application flexibility. The Sterilobe series stands out as a rotary lobe solution designed specifically for pharmaceutical, food, beverage, and other sensitive processes.
Key features of the Sterilobe series include a cover joint profile that improves self-draining capabilities, front-loading seals that can be changed in-line without major disassembly, and a corrosion-resistant stainless gear cover paired with a powder-coated bearing housing. Optimal lubrication and thoughtful gearbox design contribute to maximum seal life and hassle-free maintenance.
Rotor options add further versatility. Bi-wing rotors provide application flexibility and excellent solids-handling capabilities, while multi-lobe rotors help reduce shear and pulsation for sensitive media. Cusps with reliefs make cleaning easier and more effective. These details work together to support consistent performance and easier validation in regulated environments.
The Sterilobe series can handle flows up to 753 gallons per minute in appropriate configurations, giving facilities room to scale without sacrificing the hygienic characteristics that matter most.

Different sectors place unique demands on pumping equipment. The right hygienic solution depends on viscosity range, shear sensitivity, solids content, cleaning protocols, and regulatory expectations.
Dairy and viscous food processing often benefit from rotary lobe pumps because they handle thick products like creams, sauces, and purees while maintaining texture and minimizing product damage. Low-shear operation helps preserve quality in items that would otherwise separate or degrade under more aggressive pumping methods.
Plant-based proteins, nutraceuticals, and personal care formulations frequently involve shear-sensitive or high-value ingredients. Gentle handling reduces waste and protects the functional properties that customers expect. Easy cleanability also supports frequent product changeovers common in these categories.
Brewing, distilling, and fermentation processes require pumps that move wort, yeast slurries, or finished beverages without introducing oxygen or damaging delicate components. Self-draining designs and CIP compatibility help maintain sanitation between batches.
Meat, poultry, and prepared food lines often need reliable solids handling alongside hygienic performance. Rotary lobe pumps with appropriate rotor profiles can move mixtures containing particulates while supporting the strict cleaning regimens these environments demand.
Across these applications, the combination of gentle product transfer, cleanability, and robust construction helps facilities maintain both quality and uptime. If your process falls into one of these categories - or blends elements from several - our specialists can help narrow the options quickly. Call (404) 363-6000 for personalized assistance.
Choosing equipment involves more than matching flow rate and pressure. Start by documenting the fluid properties: viscosity at operating temperature, presence of solids or fibers, shear sensitivity, and any temperature or pressure extremes. Next, consider cleaning requirements - does the system need full CIP or SIP capability, and how frequently will sanitation occur?
Port size, seal type, and material compatibility also influence both performance and maintenance intervals. Front-loading or easy-access seal designs, for example, can significantly reduce downtime during routine service. Finally, evaluate the supplier’s ability to provide local support, spare parts, and application expertise when questions arise.
