Sanitary Lobe Pumps

Lobe pumps are used in a variety of industries including, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology.  They are popular in these diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics.

These pumps offer a variety of lobe options including single, bi-wing, tri-lobe (shown), and multi-lobe.  Rotary lobe pumps are non-contacting and have large pumping chambers, allowing them to handle solids such as cherries or olives without damage.  They are also used to handle slurries, pastes, and a wide variety of other liquids.  If wetted, they offer self-priming performance.  A gentle pumping action minimizes product degradation.  They also offer reversible flows and can operate dry for long periods of time.  Flow is relatively independent of changes in process pressure, so output is constant and continuous.

Rotary lobe pumps range from industrial designs to sanitary designs.  The sanitary designs break down further depending on the service and specific sanitary requirements.  These requirements include 3-A, EHEDG, and USDA.
