Biogas Pump / Regrowing Biogas Substrate / Resistant/ Against Solids / Self-Priming
An operator of a biogas large scale plant was not satisfied with the rotary lobe pumps of a competitor, which he used before. The rotors of the pumps were very wear intensive and outworn within a few weeks. There were also often problems with sealings and gears of this pump manufacturer.
To find the ideal pump for his biogas plant, the operator started a test, which took one year.Numerous pumps have been tested. At the end of this test procedure, the customer chose 4 Accuvon rotary lobe pumps AP 140 for his biogas plant.Not only the high quality and the ease of maintenance of the Accuvon rotary lobe pump convinced the customer, but also and above all, the Premium profile biogas rotor, which has been developed especially for the biogas field. Fibrous renewable primary products fix themselves into the grooves of the Premium rotor. This coat, which renews itself with every rotation, builds the sealing between revolving rotor and casing. This technology ensures a high efficiency as well as an almost abrasion free operation of the Premium profile rotor.

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
Accuvon's range of rotors –the Premium rotor
Premium profile– of biogas rotors
• Large sealing area
• Effective wiper edge
• Pressure-resistant
• Made of steel, stainless steel or plastic
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.
Easy maintenance– Maintenance in Place
• Reduced maintenance times and downtimes
• Maintenance at installation site by customer's in-house staff
