Description

The Rotary Lobe Pump with Rubber Coated Rotors is a self-priming, positive displacement pump designed for handling abrasive, shear-sensitive, and high-viscosity fluids across a wide range of industrial applications. Equipped with rubber-coated rotors, the pump provides gentle product handling, reduced wear, and enhanced sealing performance for reliable long-term operation.

Its synchronized dual-shaft rotary lobe design delivers stable flow with low pulsation and minimal shear, making it ideal for transferring sludge, suspensions, chemicals, food products, wastewater, and other difficult-to-pump materials. The non-contact rotor design minimizes friction and extends component life while maintaining excellent pumping efficiency.

Available with multiple rotor materials including NBR, EPDM, FPM, FFKM, PU, PTFE, stainless steel, and copper, this rotary lobe pump can be customized to meet various chemical compatibility and application requirements. Its modular construction allows quick maintenance without removing the pump from the pipeline, reducing downtime and operating costs.
