NETZSCH Pumps & Systems comprises 8 production and assembly sites in Europe, China, India, South America and the USA as well as 30 sales companies and over 200 representations worldwide. It offers a portfolio of three pump technologies – the NEMO®progressing cavity pump, the TORNADO® rotary lobe pump and the NOTOS® multi screw pump – as well as dosing technology, grinding systems and an extensive range of accessories, for use in almost any industry. The company has developed from a manufacturer of progressing cavity pumps – a segment where it is still the technology and world market leader – to a solution provider who offers positive displacement pumps with different technologies in a unique way and supports customers even with complex requirements.
NETZSCH: Smooth, worldwide communication as a recipe for success
The international corporate communication processes are complex. They require clear and defined coordination between the countries, so employees can support each other with a clear understanding of the company and its products and services. The 1,000,000th pump, a progressing cavity pump for dewatered sewage sludge, was developed at the company headquarters in Germany, the factory in Brazil designed and manufactured the components and the NETZSCH team in the USA was responsible for the final assembly. This smooth process is reflected in the clarity of the brand image, products and services, which NETZSCH communicates worldwide with Proven Excellence. Proven Excellence is both a value proposition and a performance commitment. NETZSCH uses this slogan to promise its customers excellent products and services in all areas. That the company is capable of delivering on this promise has been proven time and again since its foundation in 1873, and that is clearly reflected in the loyalty of its customers.
The 1,000,000th pump: A NEMO® individually selected
The 1,000,000th pump, a NEMO® progressing cavity pump, was built for the sewage treatment plant in the city of San Mateo in northern California. The plant processes around 60 million litres of wastewater every day. In 2017, a problem occurred with the conveying of sludge cake. The double piston pumps which were previously used for transporting the dewatered sludge could not cope with the extreme requirements and a permanent, maintenance-friendly solution with lower lifetime costs was needed. The San Mateo sewage treatment plant has been a customer of NETZSCH Pumps North America for many years and was confident in approaching the pump specialist with this request. The specifications and special requirements of the project were reviewed. San Mateo’s goal was to produce sludge cake with the lowest possible water content. The higher the water content, the higher the volume of sludge to be disposed, which in turn increases transport costs. For this reason, the target is a high solid content of approx. 18 to 22 %. The drier the medium, however, the more difficult it becomes for the pumps to convey. NETZSCH Pumps North America has excellent experience with pumping dewatered sludge cake and was able to obtain this order. Two large NEMO® hopper pumps with attached aBP modules® — to prevent bridging of the dry sludge — will be used in San Mateo in the future. Asked which difficulties this application presents for the pumps, pump specialist Jeff Bye from NETZSCH replies confidently: "This application is no problem for us. Our NEMO® pump is the perfect solution for transporting dewatered sludge and will function reliably in the long term."
Benefits of the NETZSCH modular design
NEMO® hopper pumps are part of the extensive NEMO® range known today. It is characterised by the benefits of its modular design, the media-dependent options for shaft sealing and joints as well as the geometrically stepped sizes for the rotor and stator conveying elements. A block construction design is developed from the basic design of the bearing block pump: with a consistent modular approach, the BO and SO models are developed as hopper pumps with optional aBP modules® as bridge breakers, the SF as a sludge pump with screw conveyor and the BT as a submersible pump. In addition to this, the grinders, M-Ovas® cutting plate macerator and N.Mac® double shaft macerator, protect the pumping equipment and ensure that solids are reliably reduced to a pumpable size. Therefore the danger of blockages are safely avoided, to reliably meet every demand of the environment industry.
Additionally the TORNADO® rotary lobe pumps and NOTOS® multi screw pumps from NETZSCH are available in a variety of application-specific variants, allowing NETZSCH to find the right pump for virtually any application worldwide. With this confidence, NETZSCH relies on and builds its future together with its customer from around the world – until the next million.
