Anyone who builds pumps in lots of variants knows the question: how long will this part really spend on the machine? At Dickow Pumpen, we turn, mill and assemble components in a wide range of individual configurations. Planning machining and set-up times reliably in advance has so far been mostly a matter of experience, spreadsheets and gut feeling. Together with the Mittelstand-Digital Zentrum Augsburg and Fraunhofer IGCV, we have developed a data-based addition to that in an AI application project. The tool isn't in use yet, but we have high hopes for it. The project is now being showcased as a practical example for small and medium-sized manufacturers.

Ammonia and methanol as hydrogen derivatives – safe conveying for storage and transportation of green energy
The energy transition needs storage
The decarbonisation of energy supply is a political decision and, technically, has no alternative. Because wind and solar power fluctuate strongly, growing gaps arise between generation and demand: on sunny or windy days, supply exceeds demand, while periods of low wind and sun (“dunkelflaute”) can cause shortfalls. Plants are already being curtailed at times to relieve the power grids.
Storage solves this problem by absorbing surpluses, preventing curtailment and relieving the grid. Long-duration storage is essential for security of supply – just as gas storage is today.
Autumn 2026 will be an exciting exhibition season for DICKOW. Throughout September and October, we will be present at three major international industry events focused on renewable gases, oil & gas, and hydrogen technologies. Together with our regional partners, we will showcase proven and innovative pumping solutions for demanding industrial and energy applications.
Dickow Pumpen was featured in the latest issue of the international business magazine *Business Focus Magazine*. In an interview, Managing Director Alexander Hammer discusses the company’s development, current market trends and the importance of pump technology for industrial applications.
Since its foundation in 1910, Dickow Pumpen has been developing and manufacturing high-quality centrifugal pumps at its Waldkraiburg site for demanding applications in the chemical, petrochemical, energy and process industries. Today, Dickow Pumpen’s products are also used in future-oriented markets such as sustainable fuels, environmental technologies and data centres.
The interview focuses in particular on the company’s long-term strategy. Key areas include investment in manufacturing, testing technology and digitalisation, as well as the continuous development of products and services for demanding pumping tasks. The challenges and opportunities presented by the energy transition and industrial decarbonisation are also discussed.
Collaboration with specialist suppliers
The development and manufacture of high-performance pump systems is based not only on the company’s own engineering expertise, but also on collaboration with specialist partners throughout the entire value chain. The Business Focus article highlights, by way of example, the collaboration with companies such as Bakker Magnetics, Putzier Oberflächentechnik and Kremo-Werke. These partners contribute their respective expertise in areas such as magnetic coupling technology, surface and wear protection, and the forming of stainless steel and special materials. Close technical coordination and long-standing collaboration result in solutions that meet the high demands of the chemical, petrochemical, energy and process industries.

Reliable sealing performance is one of the most critical requirements in thermal oil systems. High fluid temperatures, gas formation, and demanding operating conditions can significantly affect pump performance and seal reliability. The Dickow NKX was specifically developed to address these challenges.
The NKX combines a mechanical seal with a patented fully automatic cooling and degassing system that operates without the need for external support systems. The technology ensures a continuous supply of cooled and de-aerated thermal oil to the seal area, helping maintain optimal operating conditions.
How the Dickow NKX Works
During operation, specially designed grooves on the shaft sleeve transport thermal oil into an integrated gas separator. Within the separator, gas and liquid phases are automatically separated.
The de-aerated thermal oil then passes through a cooling section where heat is removed from both the seal chamber and bearing area. An axial fan mounted on the shaft further enhances cooling performance and helps maintain low bearing temperatures.
The conditioned thermal oil continuously supplies the mechanical seal and circulates within the system. Meanwhile, separated gases are returned to the pump casing through a conveying thread and reintroduced into the main flow.
The result is a permanently operating closed-loop system that supports reliable and stable pump performance.
Key Benefits of the Dickow NKX
- Patented cooling and degassing technology
- Continuous supply of de-aerated thermal oil to the mechanical seal
- Enhanced protection against dry running conditions
- Reduced thermal stress on seals and bearings
- Fully automatic operation without external cooling or barrier systems
- Increased operational reliability in thermal fluid and hot oil applications

Dickow Pumps has been delivering reliable pumping solutions for demanding applications in process industries, energy systems, chemical processing, petrochemicals, and decarbonization projects for decades. The NKX represents our commitment to operational reliability, engineering excellence, and long-term performance.
Liquid sulphur: Technical challenges and solutions
Liquid sulphur is indispensable across industries – yet its transfer is one of the most demanding challenges in process engineering. Even minor temperature fluctuations can lead to blockages, leaks or unplanned shutdowns. In our article published in Sulphur Magazine, we explain why only a holistic system approach ensures reliable operation – and how magnetic drive and submersible pumps contribute to maximum safety.
Liquid sulphur is a critical industrial feedstock, but its safe transfer is technically demanding. Alexander Hammer of Dickow Pumpen argues that reliable handling depends on a whole-system approach – integrating heating, piping, sealing, and operating procedures – with magnetic drive pumps highlighted as the safest option for leak-free transfer and submersible pumps as a strong fit for tank and storage applications.
IFAT in Munich is regarded as the world’s leading trade fair for environmental technologies – and this year once again confirmed its status as an international industry gathering. With around 142,000 visitors, 3,400 exhibitors from 60 countries and an exhibition area of 300,000 square metres, it provided an impressive platform for innovations in the fields of water, wastewater, recycling and sustainable urban development.
Under the motto ‘Innovations for a sustainable future – Made in Bavaria’, numerous Bavarian companies also showcased their work at the bayme vbm joint stand. The aim was to provide a strong platform, particularly for small and medium-sized enterprises, to forge contacts and tap into new markets.
