• Operating pressures usually range between 1 and 6 bar to ensure smooth, continuous transfer without aeration.

‍

Example: In dairy processing, centrifugal pumps move raw milk from refrigerated tanks to pasteurizers, protecting delicate milk proteins and preventing oxidation.

2. Mixing and Blending

These pumps maintain consistent flow rates (20–300 m³/h) into mixers and blenders, enabling uniform ingredient distribution. 

By delivering pulsation-free flow at controlled pressures (up to 4 bar), they promote thorough mixing and emulsification without causing foam or phase separation.

Example: In salad dressing manufacturing, these pumps circulate oil and vinegar mixtures through inline blenders to form stable emulsions with consistent flavor and appearance.

3. Filtration and Separation

Centrifugal pumps circulate liquids through fine filters or separators, providing stable flow rates from 15 to 200 m³/h and pressures up to 5 bar. 

This ensures efficient removal of solids and particulates, helping maintain clarity and quality without overloading filtration membranes.

Example: Juice producers use centrifugal pumps to push raw juice through fine filters, removing pulp and sediment while preserving fresh flavor.

4. Filling and Packaging

Precision pumps regulate flow rates between 5 and 100 m³/h to supply filling machines with minimal pulsation, maintaining hygienic conditions and volume accuracy within ±1%. 

Operating pressures are controlled between 1 and 3 bar to avoid foaming and product degradation during filling.

Example: Bottling plants use these pumps to fill flavored waters, maintaining product hygiene and consistent fill volumes at high speeds.

5. Cleaning Operations (CIP)

Pumps designed for CIP circulate alkaline or acidic cleaning solutions at flow rates of 10–300 m³/h and pressures from 2 to 6 bar through processing equipment.
