Sanitary pumps are often required in the food processing industry to ensure that sanitary standards are met during the processing of liquids. Types of sanitary pumps include centrifugal, drum, container, flexible impeller and rotary lobe pumps. Depending on the type of sanitary pumps used, liquids can be mixed, transferred, unloaded and processed. Likewise, high-pressure pumps can be used to clean food processing equipment in compliance with sanitary standards.
