MACHINE DESCRIPTION

A lobe pump is a type of positive displacement pump that uses two or more rotating lobes to move fluid. The lobes rotate within a casing, creating chambers that trap and transport fluid from the inlet to the outlet. They are known for their ability to handle a variety of fluids, including those with solids, and for their gentle pumping action.

ROTOR/LOBE DESIGN

Lobe pumps utilize rotors with lobes (often two or three) that intermesh without touching each other.

SUCTION PHASE

As the lobes rotate and move out of mesh on the inlet side, they create a vacuum that draws fluid into the pump.

ENCLOSED CAVITIES

The rotating lobes trap fluid within the spaces between the lobes and the pump casing.

DISCHARGE PHASE

The fluid is carried around the inside of the pump casing by the rotating lobes and is then forced out of the discharge port as the lobes come back into mesh.

GENTLE PUMPING

The non-contacting nature of the lobes minimizes shear and damage to the pumped fluid, making it suitable for delicate or viscous substances, as well as fluids containing solids.

DIRECTION OF ROTATION

Lobe pumps can often operate in either direction, offering flexibility in piping configurations.

APPLICATIONS

Lobe pumps are widely used in various industries, including food and beverage, pharmaceuticals, and chemical processing, due to their versatility and ability to handle different types of fluids.
