Microtechengineering 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, biwing, 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.
How Lobe Pumps WorkLiquid flows into the cavity and is trapped by the lobes as they rotate.
Lobe pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing. Unlike external gear pumps, however, the lobes do not make contact. Lobe contact is prevented by external timinggears located in the gearbox. Pump shaft support bearings are located in the gearbox, and since the bearings are out
of the pumped liquid, pressure is limited by bearing location and shaft deflection
