Lobe Pumps For Low Wear Transfer Of Highly Abrasive Industrial
Wastewater
Low-wear pumping of highly abrasive wastewater in industry
With our Accuvon rotary lobe pump, you can even convey industrial
wastewater with high solids content and low wear. Despite the high
abrasiveness, the design of the pump ensures a particularly long
service life, for example, when desludging the wastewater during
water jet cutting. In this way, the rotary lobe pump makes it
easier for you to treat industrial wastewater. Due to the long
service life and minimal wear, your maintenance requirements are
extremely low despite the abrasive medium. This is made possible by
the particularly innovative material mix of the Accuvon.

How does a lobe pump work?
Lobe pumps use rotating “lobes” to generate flow and move fluid
around the interior of the pump. Depending on the desired
application, a variety of lobe options can be offered including
single, bi-wing, tri-lobe, and multi-lobe. The lobes in a lobe pump
are driven by external timing gears situated in the gearbox,
meaning each lobe rotates independently to generate flow. The
external timing gears also prevent the lobes from making contact
with each other.
1. The lobes rotate around the circumference of the pump casing,
creating an opening at the suction port (inlet) as the lobes
un-mesh. This generates a partial vacuum causing the fluid to enter
the pump between the lobes.
2. The fluid travels around the interior of the casing in the
pockets between the tips of the lobes and the close-fitting casing
wall. The fluid does not pass between the lobes. When the lobes
re-mesh, pressure is generated at the discharge port/outlet,
forcing the fluid out.
Pump output is directly proportional to speed, and the direction of
the fluid flow is reversible.
