Operating principle
The parallel , 2-shaft design is common to all Rotary Lobe Pumps.
The external synchronizing gear rotates the shafts in opposite
directions.
The displacement rotors are fitted on the shafts within the pump
casing. The clearances between the rotors and casing are minimized
to completely isolate the suction and pressure areas of the pump.
The rotation of the rotors creates a series of chambers within the
pump casing. Product fills the chambers on the suction side and is
rotated circumferentially to the pressure side. This produces a
uniform flow from the suction to the discharge side with no need of
valves. The stress to the fluid is negligible as the product is
transported almost free of shear and with little pulsation and
acceleration.
