Compact, robust, powerful: The self-priming and valveless TORNADO® rotary lobe pumps are potent and require little space due to their compact design. Rotary lobe pumps offer you continuous and gentle delivery and dosing proportional to rotation speed of almost all media in a wide range of applications.
We design each pump precisely to the requirements of your application. As a result, the rotary lobe pumps offer you the highest power density and reliability. Your satisfaction is our top priority. Since all parts in contact with the medium are accessible without dismantling the piping or drive, TORNADO® rotary lobe pumps are straightforward to service and maintain. We promise you Proven Excellence – outstanding performance in all areas.
Rotary lobe pump for individual requirements
We combine decades of experience with innovative strength. The TORNADO® rotary lobe pump was developed to ensure maximum operational reliability and cost-effectiveness. Our global presence, broad vertical range of manufacturing, and direct customer contact enable us to deliver not only products but also holistic solutions. Thanks to our international alignment, we understand the regional requirements of our markets and respond effectively.
The technology of the rotary lobe pump
Rotary lobe pumps are self-priming, valveless and rotating positive displacement pumps with two rotary lobes running in a mesh. The rotation of the rotors creates a vacuum on the suction side, which draws in the pumped medium.
The rotors displace the medium into the pressure area. Two to six-room fillings are substituted per rotation, depending on the number of rotor blades. This enables dosing proportional to rotation speed. Due to the unique spatial separation between pump and gear chamber, TORNADO® rotary lobe pumps also offer you maximum operational reliability. With rotary lobe pumps, you can pump both low and high viscosity media. Due to the significant free ball passage and the low speeds, they are insensitive to blockages, clogging and foreign bodies. Varying solids contents have just as little influence on the flow rate as pressure changes. This enables continuous and powerful pumping.

FAQ rotary lobe pumps
Rotary lobe pumps are particularly suitable for pumping viscous, pasty, abrasive or solids-laden media. Typical applications include the food and beverage industry, the chemical and process industries, environmental technology, and industrial applications with stringent requirements for process reliability and product quality.
TORNADO® rotary lobe pumps from NETZSCH Pumps & Systems are characterised by their robust design, high efficiency and particularly maintenance-friendly construction. The innovative sub-assembly allows quick access to all parts that coming into contact with the pumped medium and significantly reduces downtime.
Rotary lobe pumps are suitable for low-viscosity to highly viscous media, including media containing solids. Even sensitive or shear-sensitive products can be conveyed gently, depending on the specific design and configuration.
Yes, rotary lobe pumps are self-priming and have excellent suction behaviour. This makes them ideal for applications with changing fill levels or processes requiring reliable suction.
Yes, special hygienic versions of TORNADO® rotary lobe pumps meet the high requirements of the food and pharmaceutical industries. They are easy to clean and designed in accordance with common hygiene standards.
Rotary lobe pumps require little maintenance. Wear parts can be replaced quickly and easily, often without dismantling the piping. This reduces maintenance times and increases plant availability.
All relevant original spare parts for rotary lobe pumps are available from NETZSCH Pumps & Systems. These include lobe rotors, seals, shafts, bearings, housing parts and other wear-related components. All spare parts are precisely matched to the respective pump design, ensuring high reliability and long service life.
The correct spare part can be identified by the machine number, serial number, or item number. Spare parts lists, technical drawings and the operating and maintenance instructions also assist. Alternatively, the NETZSCH Pumps & Systems service team can provide expert advice on selecting the right original spare part.
Thanks to their optimised design, rotary lobe pumps are particularly efficient. The direct drive and flow-optimised geometry help to minimise energy losses and reduce operating costs.
The experts at NETZSCH Pumps & Systems will assist you in selecting, designing and integrating the right rotary lobe pump. Based on your process data, a technically and economically optimal solution will be developed.
