450KW Rotary Lobe Pump


Solids Resistant Rotary Positive Displacement Pump

Product Description


Resistant To Solids Positive Displacement Rotary Lobe Pump



ACCUVON Rotary Lobe Pump


Rotary Lobe Pumps are self-priming, valve less, positive displacement pumps. With speed-proportional flow, they continuously deliver trouble-free pumping of liquids of various consistencies and multiphase mixtures. They are compact and operate with low shear and low pulsation.

Advantages Lobe Pumps


  • High degree of operational safety due to double-acting mechanical seals
  • Short-term dry-run capability
  • Self-priming
  • Short-term dry-run capability
  • Steel rotors with screw profile for low pulsation
  • ATEX - compliant design
  • Ease of maintenance with MIP / Maintenance in Place
  • Heated pump chamber due to pump heater cover
  • Pumping of highly viscous media




1. Quick-release cover

The robust construction of the Rotary Lobe Pump, which always features a single-sided bearing, permits use of a quickrelease cover, through which all parts subject to wear can be inspected and replaced quickly and without major effort. The cover can be removed after releasing only four ring nuts. This makes maintenance quick and easy.


2. Axial and radial casing protection

Installed axially as standard between pump casing and rotor are casing protection plates or sheets.


3. Rotors

Various rotor contours and designs based on different materials : e.g. elastomers, plastics or metal can be used, depending on the pumped medium.


4. Shaft seals

In contrast to many other positive displacement pumps, ACCUVONRotary Lobe Pumps feature the single-acting mechanical seal with quench as standard.This maintenance-free shaft seal is available in diverse sliding surface materials specially adapted to the pumped medium. Special versions in the form of pressurized or double-acting seal faces are also optionally available.


5. Non-wetted shaft

The carrier shafts of the Rotary Lobe Pumps do not come into contact with the pumped medium due to the self-sealing design.


6. Casing in block design

the pump casing is made of a single cast part and manufactured to narrow tolerances. It is available in high-quality gray cast iron, spheroidal cast iron or stainless steel.


7. Quench and control chamber

The liquid-filled and separately sealed control chamber separates the carrier gear unit from the pump chamber.

it protects the gear unit from penetration by the pumped medium while protecting the pump chamber from contact with gear oil. It also serves as the quench chamber for the mechanical seals.


8. Carrier gear unit and timing gear

The timing gear and carrier gear unit represent a separately sealed component. The high quality and extremely sturdy gear wheels ensure even, smooth operation, as well as long service life
