Pumps for the Process Industry
Substances endangering health and the environment, highly viscous fluids containing dry solids or shear sensitive fluids ask for pumps capable of conveying most difficult media in hermetically closed systems without compromising safety. Positive displacement pumps are successfully proved in many markets, such as:
- Paper Manufacturing
- Paints & Coatings Industry
- Mining
- Dosing Technology
The low NPSHr value of two compact rotary lobe pumps ensures precise and reliable decantation of water from a vacuum tank
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 ...
New techniques of immediate repairs for road surface damage:
Progressing Cavity Pump ensures efficient conveying of cold asphalt
According to the German automobile club ADAC, there were 538 roadworks on German motorways in September 2018, causing traffic jams and delays. More...
Robust rotary lobe pump design enables a six times higher service life
of pumps handling abrasive ceramic slip
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...
Rotary lobe pump meets the challenge of highly abrasive bonding primer and achieves three times longer service life
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.

Positive displacement pump empties tankers without interruption
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
Materials for surface coating represent extreme challenges to pump technology
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.

Flexible rotary lobe pumps convey kaolin slurry quickly and reliably despite reduced space
"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
Special rotary lobe pumps meet even the strictest legal requirements at the conveying of fatty acids
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
Space-saving and high-performance in the process industry:
New compact rotary lobe pump increases mobility and efficiency in production
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...
Combination of several barrel emptying units enables exact mixing of different material components
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
