Substances hazardous to health or the environment; products that are highly viscous, sensitive, or contain solids; and even the most demanding products in air-tight systems require pumps capable of high performance. NETZSCH has been well known for decades as a dependable and competent partner in these areas. Of the almost 500,000 NETZSCH PUMPS® distributed worldwide, 150,000 are operating in the chemical industry.
Even for difficult applications in the explosives, dyes and paints, or construction materials industries, NETZSCH has the answer. Experts from all fields find the ideal solution for even the most challenging application.
Until August 2017, two centrifugal pumps were used to decant a fine coal screen vacuum tank in an open-pit coal mine of a company in Australia. Since their high NPSHr value reduced the capacity of the plant, its management decided to replace both units with more efficient models. Read more ...
The ceramic production process offers a range of forming processes which can be categorised into the basic types of pressing, plastic forming and casting. For ceramic slip casting, for example, a watery suspension is poured into a porous mould which drains liquid from the slip. More...
One of the products which the building materials manufacturer Knauf makes in Iphofen is a concrete primer. What is intended to ensure that plaster evenly bonds onto smooth walls in construction does however create problems when filling: the plaster primer contains dispersion and has a mineral solid content of around 60 percent, which has an effect like emery paper in the rotary lobe pump feeding the filling station.

Emptying tankers can cause problems for many pumping processes. The difficulties involved are air pockets which cannot be avoided when attaching a pipe. The gas bubbles initially lead to reduced performance and irregular running until the product flow stalls as the gas inflow further increases. More
The printing and ink industry represents one of the most versatile application sectors for delivery systems: The areas of application include the reliable supply of abrasive paper fillers and corrosive gluing agents just as much as the exact metering of high-viscosity printing inks and varnishes.

"White gold" – this description of porcelain was also used in the past for paper, for a good reason. Both are based on kaolin, a special clay that gives the materials their radiant white. Kaolin is not only used as a coating in paper production, but as a filling as well. More
Every commercial and industrial company in Europe is subject to a multitude of regulations for the protection of staff, users and the environment. This not only affects the manufacturing machines themselves, but also the pump systems being used. More
The Italian personal hygiene product manufacturer is based in Northern Italy and its products include soaps and shampoos for various markets. Against the background of performance optimisation, there is ever greater recognition of surface area as a valuable resource in all industrial sectors. For processes in which smaller volumetric flows suffice we designed the all-metal pump, which is specially for media that are demanding in chemical or hygiene terms. It offers a pumping capacity of up to 8 m³/h. More...
The higher the requirements are in terms of the characteristics and high performance of modern materials, the more individual components have to be combined and accurately mixed to produce them. This means correct dosing is essential and accuracy requirements of ±1 percent are not uncommon. More
