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
