The pump features a one-piece, flow-optimized housing and improved lobe geometry for enhanced volumetric efficiency and gentle handling of shear-sensitive or solids-laden media. New wider lobe tips reduce backflow, while the axial and optional radial wear plates available in highly abrasive- and chemical-resistant materials extend wear life even in harsh operating environments.

In terms of serviceability, the XXLB-F includes Full Service-In-Place (FSIP®) access, enabling all wetted parts lobes, wear plates, and seals—to be replaced from the front without removing the pump from the piping. The pump also features the NETZSCH Gearbox Security System (GSS), an innovative air-gap barrier between the mechanical seal and gearbox that prevents fluid ingress, protecting gears and bearings from contamination and enabling predictive maintenance. Other key advantages include high suction capability (self-priming without external vacuum devices), consistent flow across varying back pressures, reversible flow direction, and mobile configurations for emergency or rural installations. 

Ideal for use in environmental, energy, chemical, and industrial markets, the pump handles a broad range of media, offering a flexible solution for both new systems and retrofit projects.
