Rotary Lobe Pumps: Powerful Solutions for Demanding Tasks
Compact, robust, powerful: Rotary lobe pumps are used for reliable, gentle and efficient pumping of demanding media. Thanks to numerous design variants, a wide range of applications is covered.
Whether stationary or mobile, for industrial, chemical or hygienic processes, and with special drive concepts, NETZSCH Pumps & Systems, the global specialist in handling complex media, offers the optimal solution. We will show you how and in which applications you can benefit from rotary lobe pumps.
Rotary lobe pumps for environment, energy and agriculture
Customised Consulting
Rotary lobe pumps for the environmental, energy, and agriculture sectors are designed for robust, efficient, and flexible pumping. They are ideal for pumping sludge, manure, substrates, biogas media or liquids containing solids, ensuring reliable, continuous operation. Thanks to their gentle pumping characteristics, the media structures are preserved while high-volume flows are achieved. Different drive concepts, high dry-running capability, and maintenance-friendly designs make rotary lobe pumps, such as the TORNADO® T1-F, an economical solution for sewage treatment plants, biogas plants, agricultural businesses, and energy-generating processes. With their high efficiency and durability, they also make an essential contribution to sustainable and resource-saving applications.
Mobile rotary lobe pumps on trailers or carts
Mobile rotary lobe pumps mounted on trailers or carts provide a flexible, robust solution for conveying difficult media precisely where needed. With the TORNADO® mobile, NETZSCH offers a self-priming rotary lobe pump from the proven TORNADO® series, mounted on a car or truck trailer and ready to operate quickly even at unusual or changing locations. This makes mobile rotary lobe pumps, such as the TORNADO® mobile, suitable for demanding applications in areas including environmental and disaster control, agriculture, chemistry, and construction, ensuring efficient pumping of large, solids-laden media across changing locations.
Rotary lobe pumps for the chemical industry
TORNADO® rotary lobe pumps for the chemical industry must meet the highest requirements for safety, durability, and process stability. They are used to convey aggressive, toxic or abrasive media as well as viscous or solid-laden liquids. The TORNADO® T.Proc® rotary lobe pump is a solution designed specifically to meet these requirements. It impresses with its robust construction, chemical-resistant materials and a sophisticated sealing concept, guaranteeing safe and reliable operation. The virtually pulsation-free pumping ensures constant process conditions, while the maintenance-friendly design reduces downtime. The TORNADO® T.Proc® thus offers a powerful and economical solution for demanding applications in the chemical industry.
Rotary lobe pumps for hygienic applications
Rotary lobe pumps for hygienic applications meet the highest requirements for product safety, cleanability and process stability. They are used wherever sensitive media, such as food, beverages, or pharmaceutical products, need to be conveyed gently and without contamination. With the TORNADO® T.Sano®, NETZSCH Pumps & Systems offers a rotary lobe pump developed for hygienic applications, also available with smooth surfaces. This makes it very easy to clean the pump from the outside. Both versions feature smooth, low-dead-space surfaces, high CIP and SIP suitability, and particularly gentle pumping characteristics. This preserves your media’s quality and structure while ensuring safe, efficient, and standard-compliant operation. The TORNADO® T.Sano® thus stands for reliable hygiene, high cost-effectiveness and Proven Excellence in sensitive production processes.
Rotary lobe pumps with hydraulic motor
Rotary lobe pumps with hydraulic motors offer a highly flexible drive solution and are ideal for mobile applications, such as tanker trucks and other vehicle-mounted systems. The hydraulic motor drive allows you to operate independently without an electrical power supply and can be easily integrated into existing hydraulic systems. Thanks to their extremely compact design, low weight and high power density , these rotary lobe pumps are optimally designed for applications with limited installation space. At the same time, they guarantee reliable, gentle pumping of a wide variety of media and impress with their robustness and high operational reliability.
Rotary lobe pump with barrier pressure system
Rotary lobe pumps with a barrier pressure system are specifically designed for applications that place the highest demands on tightness, process reliability, and plant availability. Additional flushing, quenching, or barrier-pressure systems are often required to ensure proper and safe operation of shaft sealing systems, which flush the seals with clean pumped medium or reliably seal them. Among other things, quench tanks, permanent lubricant dispensers, barrier pressure systems and thermosiphon systems for double-acting mechanical seals are used for this purpose. NETZSCH offers rotary lobe pumps with barrier pressure valves, including all relevant API seal plans, enabling optimal adaptation to the respective application. This ensures safe, long-lasting and standard-compliant operation – even with critical or demanding pumped media.
Rotary lobe pump with PTO shaft
Rotary lobe pumps with PTO drive are the ideal solution for flexible and powerful use in agriculture. For agricultural applications, the TORNADO® T1 rotary lobe pump is also available with a PTO drive and can be operated directly via a tractor. Its robust design, high reliability and easy integration into existing agricultural processes make the rotary lobe pump with PTO shaft an economical and practical solution for demanding pumping tasks.
Rotary lobe pump in compact design
Rotary lobe pumps in a compact design offer maximum performance with minimum space requirements. Thanks to their space-saving construction, installation is easy even in confined spaces. On request, the motor can be positioned directly above the pump, reducing your space requirements. This design facilitates integration with existing systems, reduces installation costs, and increases flexibility in system planning. Despite its compact dimensions, the rotary lobe pump impresses with its high efficiency, reliability and long service life.
In addition to many different designs of rotary lobe pumps, NETZSCH also offers unlimited service, which does not end with the purchase. Whether you are working on a remote oil platform, pumping complex media in the middle of the desert, or operating in rough terrain in the mountains, we are always there when you need us.
