Viking Hygienic Pumps

Viking Hygienic pumps serve sanitary product transfer in food, beverage, dairy, personal care, and other process applications requiring cleanable equipment and appropriate product handling.

Viking's hygienic range includes rotary lobe and circumferential piston designs. Select the technology for product properties, pressure, cleaning requirements, and the desired operating range.

Timed rotors turn without contacting each other, carrying product around the casing toward the outlet. External timing gears coordinate rotor movement while the drive supplies power.

Circumferential piston designs use rotor geometry and sealing paths that differ from conventional lobes. The resulting performance should be compared using model-specific data for the actual product.

Suitable models can transfer viscous materials such as sauces, syrups, and creams. Inlet conditions, operating speed, temperature, and product behavior determine achievable flow.

Particle handling depends on rotor geometry, passage dimensions, speed, and product fragility. Provide particle size and the acceptable level of damage when requesting a selection.

Appropriate hygienic positive displacement designs can support gentle transfer. Product quality also depends on speed, pressure drop, piping, and the amount of recirculation in the system.

Hygienic design addresses fluid-contact materials, surface condition, cleanability, drainage, seals, and access. Suitability requires evaluating the exact model against the process's sanitation requirements.

Selected configurations support clean-in-place procedures. Validate flow, cleaning chemistry, temperature, drainage, and coverage for the actual installed system and the product being processed.

No. Certifications apply to specified products and configurations. Request documentation for the exact pump, seals, materials, and intended service when a project requires a particular standard.

Provide flow, differential pressure, viscosity, temperature, particle details, and cleaning requirements. Include inlet piping and supply-vessel conditions because insufficient feeding can limit performance.

Adjustable speed can match delivery to process demand. Confirm motor and drive compatibility and minimum operating limits, particularly when the same system handles products of different viscosities.

Seals must suit product chemistry, temperature, pressure, and cleaning cycles. Seal arrangements may also require compatible support fluids or monitoring to meet the process's operating needs.

Inspect rotors, seals, clearances, bearings, and gearbox components according to the manual. Verify correct reassembly and sanitation after maintenance on product-contact parts.

A replacement may be practical after comparing performance, connections, footprint, cleaning method, and controls. Product trials can help assess sensitive materials before committing to a new design.
