In many production plants, unwanted pressure surges arise which are generated by switching on pumps, by temperature changes in enclosed liquids or by quickly switching valves, for example. Opening valves can also result in pressure surges if the media supply is at a high level and the fluid column to lower plant components suddenly starts moving. mongoose shaker
These pressure surges may damage plant components, such as filters, sensors, pumps and piping. Likewise, these pressure surges can result in shut-off valves briefly opening inadvertently. This can, in turn, result in possible contamination of the medium. In the worst case, they can result in downtime due to required repair work or a loss of product.
As a solution to this problem, GEMÜ has launched the GEMÜ 652 pulsation damper on the market. It is designed to open up as much volume as possible in a given operating range and thereby absorb and compensate for the pressure surge. Its body does not include a sealing weir, meaning that it is not suitable for shutting off media. The actual expansion volume is opened up by the moving diaphragm. By using different actuator sizes and spring sets, it is possible to adjust the operating range and the volume that can be compensated for. Increased expansion volume can be achieved by installing multiple pulsation dampers in series.
The control air connector is only used for assembly. Actuation via control air is not required for operation, as its function is accomplished solely using spring force.
The GEMÜ 652 pulsation damper is available in the nominal sizes DN 15 to DN 80 (diaphragm size 25 to 80). To ensure high flexibility of applications, the valve bodies and diaphragms are available in various materials and designs. Due to the diaphragm valve technology used, the product complies as standard with the current standards in the foodstuffs and pharmaceutical industry, such as BSE/TSE, FDA, USP Class VI and Regulation (EC) no. 1935/2004.

Ingelfingen-based technology company GEMÜ has been named a “Digital Champion” by Focus Money and Deutschland Test for the third time running. GEMÜ was awarded a ranking of second place among companies recognized in the “machinery and plant construction” sector.
With its new patented seal system for filling needle and filling pipe systems, valve producer GEMÜ has brought to market the first ever adaptation option for filling needles that ensures hermetic separation between the actuator and medium. This means that any lift effect and contamination of the medium can be avoided.
The new ball valves in the GEMÜ BB0F series from valve specialists GEMÜ cover a wide range of applications in the chemical industry thanks to their configuration and the available construction and actuator versions.
The production of cultivated meat is based on known biotechnological processes that are identical to those used in other large-scale applications for cell culture technology. For this future market, GEMÜ offers complete valves, as well as measurement and control systems, from a single source.
The Ingelfingen-based technology company GEMÜ is being awarded the title of “Global Market Leader” for yet another year, earning the distinction “Champion 2024” as part of the global market leader index of the University of St. Gallen and the Academy of German Global Market Leaders.
The GEMÜ lettering has barely changed in almost 60 years. While the logo has been developed during this time, the letters have largely remained the same. In October 2023, the Ingelfingen-based technology company will introduce its new company logo.
