The new Type 3598 Cryogenic Valve was specially developed to meet the requirements of cryogenic applications. The valve is available in sizes up to NPS 8 and pressure ratings up to Class 900 and is suitable for temperatures down to –196 °C. The valve is optimized to handle high pressure drops. It has a cryogenic extension bonnet and circulation inhibitor that ensure a perfect temperature distribution and minimize energy loss to the atmosphere. The top-entry design facilitates work on the valve: the valve can be serviced without having to remove the enclosure or insulation it is installed in. The valve seat, piston and circulation inhibitor can be accessed directly after removing the actuator.

Lower actuator thrusts and smaller actuator sizes can be used thanks to the standard pressure balancing by a piston. This allows customers to save money on initial investment and reduce the cost of installation and servicing over the actuator’s life cycle. Possible fields of applications for Samson’s high-pressure cryogenic valve include air separation units (ASU) and marine applications, for example to store and transport cryogenic gases on LNG carriers.

With the Type 3598 Cryogenic Valve, the company is responding to the customers’ growing demand for increasingly larger units. Further additions to the modular design, e.g. larger valve sizes and higher pressure ratings, are being planned.

Over the past 112 years, the firm has been driving forward new developments and introducing market innovations. Today, Samson is a worldwide leader in the manufacture of expertly engineered control valves and accessories for all industrial processes.

Bottrop pump specialist is now the holder of the TOP 100 seal for exemplary innovation management



“All things flow” – standing still is not an option: At SEEPEX, one of the world’s leading manufacturers of progressive cavity pumps, the company claim goes far beyond the manufacture of first-class high-tech pumps. With new developments such as the holistic “Digital Solutions” concept, the medium-sized company is leading the classical field of mechanical engineering into the future in a targeted manner. Now the Bottrop-based specialist can officially count itself among the nationwide innovation elite. On June 19, SEEPEX was awarded the “Top 100 Seal” for exemplary innovation management and above-average innovation successes.

In Bottrop, the “InnovationCity Ruhr”, future-oriented ideas and solutions have been developed for the past ten years with the aim to meet the challenges of climate and structural change in urban areas. And there are also companies that have successfully and for a long time already been contributing to such innovations at the heart of the Ruhr area. For almost 50 years, the family company SEEPEX in Bottrop has been developing and building progressive cavity pumps, macerators and control systems. The manufacturer has continuously developed its pumps further and introduced new pump technologies in order to constantly improve its own products and, for example, enable easy maintenance. Digital solutions for the control and monitoring of pumps have long been offering great added value; in most cases, these are developed together with key customers and tailored to their individual needs. The SEEPEX management has risen to the challenge of digital change at an early stage. In the segment of progressive cavity pumps, which conveys ‘delicate cargo’ such as raspberries just as gently as thick chunks of sewage sludge in the environmental technology sector, the company plays a pioneering role within the international industry with its “Digital Solutions”. The holistic concept offers a portfolio of mobile and networked services, ranging from digitally supported maintenance of the pump using virtual reality, through digital pump management with simple spare parts ordering, to data-based services.

80 percent of SEEPEX products are exported worldwide. The company, which was founded in 1972, now has 18 subsidiaries and branches outside Germany, as well as distribution centers in over 70 countries. There are more than 800 employees worldwide, 423 of whom work at the company headquarters in Bottrop. This is also where the heart beats for new ideas.

For the top innovator, digitalization is the most important innovation of the past few years. Pumps can now be monitored in real time. With the SEEPEX tools, maintenance can be carried out partly by the customers themselves and even remotely. This means that customers can access, control and monitor the pumps with a mobile phone or tablet. The measured values are loaded into a cloud where they can be analyzed by customers or by SEEPEX. An internal team of data analysts deals with data mining and anomaly detection. This saves time and costs and also secures production, as malfunctions can be avoided.

In Bottrop, a dozen employees consistently oversee the digital change, while the management commits a large amount of time towards pushing innovations forward. Every year, around 200 suggestions for improvement are received from the workforce, two-thirds of which can generally be implemented. Between 2016 and 2018 alone, SEEPEX was granted 13 patents at both national and international level, plus certificates attesting to the pumps’ highest standards. For example, they meet the highest hygiene standards in the food sector and are certified according to EHEDG. Even the iF Design Award for innovative industrial design has already been awarded to the SEEPEX technology SCT because besides all of its functionality, easy handling is also to the fore.

All this and much more impressed the jury of the TOP 100 competition, which was held for the 27th time this year. Innovation researcher Prof. Dr. Nikolaus Franke from the University of Vienna and his team tested around 120 parameters for the selection of the top companies on the basis of a scientific system. Here, SEEPEX was easily able to maintain its position in the league of the most innovative German medium-sized companies according to the strict criteria. An award ceremony with the mentor, science journalist Ranga Yogeshwar, has had to be cancelled this time due to the corona restrictions. In Bottrop, the management and staff are nevertheless very happy: “The same passion with which we have been working continuously for almost 50 years on the technical side to create top products also drives us to work together continuously on the future. We are proud that SEEPEX is now one of the TOP 100,” says owner and CEO Ulli Seeberger.

“Innovative medium-sized companies like SEEPEX GmbH from Bottrop are not afraid of change, but see it as an opportunity. In the scientific selection process, the company impressed in the largest size category (companies with more than 200 employees) especially in the categories of “External Orientation / Open Innovation” and “Innovative Processes and Organization” according to the competition initiators. They were particularly impressed by the way the company works on new products and services: Innovations are created in a close exchange with the customers. Innovations are developed step by step and tested with the most important customers (“lead users”). “Only when the customer successfully benefits from the added value is further development – or adaptation – carried out,” is how SEEPEX CTO Dr. Christian Hansen explains the procedure. “It is not uncommon for us to discover potential for improvement among the customer’s processes as well – for us, this is an important approach and confirmation that we can provide our customers with greater support in this respect.”

Since 1993, compamedia has been awarding the TOP 100 seal of approval for special innovative strength and above-average innovation successes to small and medium-sized companies. Since 2002, the scientific management has been in the hands of Prof. Dr. Nikolaus Franke. Franke is the founder and director of the Institute for Entrepreneurship and Innovation at the Vienna University of Economics and Business Administration. The mentor of TOP 100 is the science journalist Ranga Yogeshwar. Project partners are the Fraunhofer Society for the Promotion of Applied Research and the German Association for Small and Medium-sized Businesses (BVMW). As media partners, manager magazin, impulse and W&V provide advice and support for the company comparison. More information is available at

TDK Corporation (TSE 6762) announces the introduction of the EZA2500W-32048 TDK-Lambda brand bi-directional DC-DC converter model to its EZA series. The extended high voltage range now covers 260 to 400Vdc and the lower voltage 36 to 65Vdc. The operating temperature has been increased to -10 to +50°C. Double sided protective board coating and long-life dust resistant fans have also been included.

Designed for energy storage systems with rechargeable batteries, this 2500W digitally controlled, compact 1U power supply can seamlessly change conversion direction from high voltage dc sources, powered by solar or wind, to 48Vdc batteries and vice versa. Other applications include lithium-ion battery testing as well as the use of regenerated energy from robots, cranes, autonomous ground vehicles and lifts. The EZA2500 can be used to replace large power resistors currently used for lift braking and use that previously dissipated energy to charge batteries. That stored energy can be used to either provide peak power for high torque demands or as battery back-up for power cuts.

The output voltage and current can be programmed and monitored using the RS-485 communications port. Multiple units can be operated in parallel by using the RS-485 interface to set units for “droop mode” current share. Alarm signals are also accessible, as well as remote on/off and under/over voltage functionality. The high voltage (grid) to low voltage (battery) isolation is 3,000Vac, grid to ground 2,000Vac and battery to ground 500Vac.

The dimensions for the EZA2500 are 43.6mm (1U) high, 423mm wide and 400mm deep. All models in the EZA series are certified to the IEC/EN/UL 60950-1 and IEC/EN/UL 62368-1 safety standards with CE marking for the Low Voltage, EMC and RoHS Directives. A five-year warranty is standard.
