A South Korean cement plant uses an ONIXline Rotary Lobe Pump for charging the furnaces with secondary fuels.

Due to the high chemical stress caused by the secondary fuels containing solvents, the pump casing of the ONIXline pump is made of stainless steel. A replaceable casing lining protects the pump casing from wear caused by abrasive components in the pumped media with high solids content. The stainless steel rotors with screw profile convey the fuels very evenly and with low pulsation.

The service life is significantly better than that of the gear pump used before. In addition, maintenance work requires a lot less time and effort.
