Double diaphragm pumps operate using an oscillating positive displacement principle. The pump consists of two main fluid housings and a central air control section. Inside each housing, a flexible diaphragm is mounted vertically and connected to a shared shaft. As compressed air enters and exits the air chambers, the diaphragms move in a coordinated push pull motion.
Reliable water access is essential not only for households and industry but also for maintaining green spaces that enhance quality of life for urban residents. Japanese underground construction specialist Sansui Kaihatsu Co., Ltd., based in Miyoshi City, Hiroshima Prefecture and serving customers across Japan, drilled a 250-meter water well in Toyota City, Aichi Prefecture to supply sprinklers for a local golf course — powered by Atlas Copco’s Y35 portable air compressor.
Dutch drinking water utility Brabant Water, in partnership with Xylem, is creating one of Europe’s largest digital water networks, serving 2.6 million residents and businesses across North Brabant. To meet rising demand, the utility is deploying a digital twin and smart metering solutions to build a more efficient, resilient water system.
Nutrient deficiencies, over-fertilisation and crop losses: many greenhouses struggle due to inaccurate nutrient supply and fluctuating water quality. Lutz-Jesco will be demonstrating what you can do about this at Agritechnica in Hanover. On display: a dosing pump from the Magdos series and the Minichlorgen T chlorine electrolysis system.
The Wilo Group is calling for water resilience measures to be implemented more rapidly. Together with numerous other global market leaders, the water technology group has signed the “Business Leaders’ Open Call to Accelerate Action on Water”. The public appeal was initiated by the Water Resilience Coalition of the CEO Water Mandate, an initiative founded by the UN Secretary-General and the UN Global Compact.
Whether adhesive, lubricant, grease, silicone, polyester, or epoxy resin – applying media accurately and precisely inside an interior geometry is a technically demanding task. To enable industrial manufacturers to achieve precisely this with maximum efficiency and precision in cavities, internal threads, or shaft-hub connections, for example, preeflow has added the eco-SPIN to its portfolio.
EBARA Corporationhas been selected as the contracting party and signed a prototype pump contract for the “FY2025 Stardust Program R&D of High-Efficiency Heat Dissipation System for Digital Signal Processing – Prototype of Performance Verification Pump for Two-Phase Flow Heat Dissipation System (Part A) (hereinafter: this matter),” which was announced by the Japan Aerospace Exploration Agency (hereinafter: JAXA) through a competitive bidding process.
Vibration in rotating machinery is a leading cause of premature failure, costly downtime, and safety hazards. For operators of vertical motors, one of the most important vibration-related concepts to understand is reed critical frequency (RCF). This natural frequency of a motor system plays a central role in determining whether a motor will operate smoothly or succumb to damaging resonance conditions.
Water is a vital, indispensable resource—for us humans, of course, but also for the economy. The management and protection of water resources, ecosystems, and drinking water is one of the cornerstones of environmental protection and is becoming increasingly important. The market for water treatment solutions is therefore growing rapidly, but at the same time is extremely fragmented, as there are so many different suppliers.
The Endress+Hauser Group has opened a new development and production center for temperature measurement and system products at its Nesselwang site in southern Germany’s Allgäu region. The new addition further solidifies the family-owned company’s commitment to the region and expands its global network.
Electricity Generating Authority of Thailand (EGAT) has awarded international technology group ANDRITZ a contract to replace the two pumped storage units at the Srinagarind hydropower plant with new, state-of-the-art units.
