Low-Pulse Operation And Compact Design Of Rotary Lobe Pump
The Working principle of ACCUVON Rotary Lobe
- All rotary lobe pumps are designed according to the same
construction principle. Two displacement elements / rotors mounted
on parallel shafts are supported by an external gearbox .
- The two rotors turn in opposite direction with minimal radial and
axial clearances. They neither touch each other nor the surrounding
pump casing. The shafts are synchronized by spur gears.
- The rotors are shaped so that they seal the suction chamber against
the pressure chamber in any position. This sealing is only achieved
by the gap, not by additional seals or valves. The removable pump
cover seals the pump housing and allows easy access from the front
to achieved easy maintenance for all parts.

Advantages
- Low shear / Sensitive handling and conveying of products
Rotary-lobe-pumps are well known in applications where a low shear
is required.
The reasons are :
- The low speed of the pumps,
- The little friction through the rotating elements
- Large chambers inside of the pumps
- Quick flow through the pump
- Service-life of the wearing parts
High service life as the conveying elements are guided without
friction on eachother. Wear is only produced by the fluid and the
contained solids
Good for positive displacement pumps, as ball-entering diameters
are relatively large up to 16 cm. No danger of sedimentation. Even
when handling heavy solids suspensions, as all casings-areas are
continuously cleaned by the conveying elements.
