Corrosion Resistant Biogas Pump


Antiwear Biogas Pump


Multipurpose Biogas Lobe Pump

Product Description


Biogas Rotary Lobe Pump / Abrasive Biogas Substrate / Low-Wear / Resistant To Pressure



An operator of a biogas plant was looking for a reliable pump for pumping very abrasive biogas

substrate from a fermenter into a secondary fermenter. The rotary lobe pump which had been

used before had a very high wearing of rotors.

It was very important for the operator of the biogas plant to use a pump in his plant, which has

high durability, works low-wear and is easy to maintain in case of maintenance. Because of the

design of the pipe connection system, the pump had to manage an underpressure of -0.4 bar.

The customer chose a Accuvon rotary lobe pump AF 125. The speed of the AF 125 is controlled

via a frequency converter, depending on the underpressure. The underpressure as well as the

pumping pressure will be measured with electronic manometers.

The customer is very satisfied with the Accuvon AF 125.

operating principle


• Self-priming, valveless, positive displacement pump

• Designed with two shafts with parallel axes

• The shafts move relatively to one another thanks to external timing gear

• The displacers (=rotors) roll off each other with minimum axial and radial clearance

• In every position, the rotors and casing close the suction chamber against the pressure chamber

• Gentle, low-pulsation pumping

• For viscous, solid, abrasive or shear-sensitive media

axial and radial casing protection


To protect the pump casing from abrasive media and solids, we developed replaceable casing protection plates and liners several years ago.

The casing protection is replaced in a few steps, based on the MIP principle.
