Lobe Pump Overview Lobe pumps are used in a variety of industries such as pulp and paper, chemical, food, beverage, etc These pumps offer superb sanitary qualities, high efficiency, reliability and corrosion resistance

How Lobe Pumps Work – Step 1 Initially, the lobes create an expand in volume on the inlet side of the pump Liquid flows into the cavity and is trapped by the lobes as they rotate LOBE

How Lobe Pumps Work – Step 2 Liquid travels around the interior casing (between the lobes and the casing) It does not pass between the lobes

How Lobe Pumps Work – Step 3 Finally, the lobes forces the liquid under pressure through the outlet

Advantages Can pass medium solids There is no metal-to-metal contact between the lobes Superior CIP (Cleaning-in-Place)/SIP (Steaming-in-Place) capabilities Positive suction Non-pulsating discharge.

Disadvantages Needs timing gears Needs two seals
