Discover how rotary lobe pumps increase efficiency in sewage treatment plants and contributing to the improvement of wastewater treatment.
The roller of rotary lobe pumps in modern wastewater treatment
Rotary lobe pumps play a central role in modern wastewater treatment. They are used in various phases of the collection and treatment process, from pumping in the sewer system to sludge treatment and disposal of the sewage sludge. Their ability to convey both viscous and solid-containing media makes them particularly valuable in this area.
With their robust design and ability to move large volumes of fluid efficiently, rotary lobe pumps contribute significantly to the performance and reliability of sewage treatment plants. Their flexibility and versatility make them a preferred choice for many operators of wastewater treatment plants.
Advantages of rotary lobe pumps compared to conventional pump systems
Rotary lobe pumps offer several significant advantages over traditional displacement pumps. One of the biggest advantages is their high efficiency. They can pump large quantities of fluids with comparatively low energy consumption, resulting in significant cost savings.
Another advantage is their ability to convey reliably even when the medium contains solids and foreign matter. This reduces the need for complex pre-treatment and minimizes the risk of clogging. In addition, rotary lobe pumps are easy to maintain due to their simple and robust design, which further reduces operating costs.
Technical features and operating principle of rotary lobe pumps
Rotary lobe pumps work according to a simple but effective principle. Two counter-rotating rotors rotate in a housing, generating a continuous flow. The pump is designed so that the rotors are precisely aligned to each other and run without contact along the housing, which reduces wear and extends the lifetime of the pump.
Another technical feature: they are self-priming, which means that they can evacuate air from drained pipes or prime waste water and sludge from deep pits. This is particularly useful in applications where the pumping is switched on and off regularly. In addition, rotary lobe pumps can pump in both directions, which further increases their flexibility. This saves a lot of money, especially when constructing pipelines. Instead of installing complex pipes and many valves, the pumping direction is simply reversed.
Case studies: Successful application of rotary lobe pumps in sewage treatment plants

Many sewage treatment plants around the world have recognized and successfully implemented the advantages of rotary lobe pumps. For example, a German sewage treatment plant was able to optimize its sludge treatment by installing a rotary lobe pump, which reduced sludge dewatering runtimes by over 25 %. The gas yield of the digestion tower was also increased, thus reducing the operating costs of the plant.
Another case study from the USA shows that the application of rotary lobe pumps has helped to reduce maintenance times and costs. The plant reported a significant reduction in downtime and drastically shortened running times, resulting in a significantly longer lifetime for the pumps. Overall, this also contributed to a clear increase in reliability and productivity.
Presentation of the VX series and IQ series from Vogelsang and their specialization in wastewater applications
The VX series from Vogelsang is specially designed for the requirements of wastewater treatment. These pumping units are characterized by their high performance, robustness and durability. They are capable of efficiently pumping large quantities of fluids containing solids, making them ideal for application in sewage treatment plants.
A special feature of the VX series is its modular design, which allows for easy service and adaptation to specific requirements. In addition, these pumps offer excellent energy efficiency, resulting in lower operating costs and a better environmental balance.
With the IQ series, Vogelsang has succeeded in further developing the technology of rotary lobe pumps. One of the reasons for this is that the design has been reduced to just a few individual elements. The pump housing of the IQ series consists of a single part. It can be dismounted in just a few simple steps, freeing up access to the pumping elements. The pump remains completely screwed into the pipe. Even compared to the rotary lobe pumps in the VX series, handling is even easier.
With the quantity of central spare parts reduced by half compared to the conventional design, expenditure on replacement parts is also reduced. In addition, less time is required for service and parts replacement: IQ series pumps are designed so that replacement of all wear parts - including rotary lobes, wear plates, pump housing and gaskets - can be completed in less than half the time.
Thanks to the variable connection parts on the IQ series pumps, they are suitable for most common installation situations. This means they can be quickly and easily attached or installed in a wide variety of positions without the need for special connections - even on tankers or in mobile units.
With the IO series, Vogelsang is setting new scales in wastewater treatment and contributing to the sustainable and efficient design of sewage treatment plants.
