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.
Global pump OEM Sulzer has won an order to supply multiple water injection packages to Seatrium for Petrobras’ next generation P-84 and P-85 Floating Production Storage and Offloading (FPSO) vessels. The project was awarded to Sulzer due to its track record of providing industry-leading pumps for the most challenging offshore oil and gas operations globally. For both vessels, Sulzer has met the strict acceptance criteria and application requirements of the end user.
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.
The European tech company Wioniq introduces WATER+, an AI-based monitoring solution developed by Pluvion. The solution helps municipalities detect hidden leaks and reduce unnecessary treatment costs.
In a major leap toward water security in the south of France, Eau d’Azur has launched the country’s first smart water network. The €5.9 million initiative will modernize 3,000 kilometers of infrastructure across the Côte d’Azur, aiming to reduce leaks, cut energy use, and secure reliable water service for over 500,000 residents.
National Pump Company highlights its line of deep well vertical turbine pumps, engineered to deliver reliability and versatility for demanding water extraction projects.
Hoyer, a global supplier of electric motors and automation solutions, and VMS Group, a leading marine service provider, announced the creation of Hoyer VMS Group. The new company combines complementary strengths to deliver a unique global offering for power and motion solutions across marine and industrial markets – one partner that can supply, service, repair, and optimise critical systems throughout their lifetime.
ProMinent is expanding its DULCONNEX digital platform with the new Remote Control Module. The platform connects measuring, control and metering devices, enabling processes to be monitored centrally, data to be evaluated and devices to be controlled directly from a PC workstation – conveniently from a remote location.
Particle detectors on the Large Hadron Collider (LHC) at CERN, the European Laboratory for Particle Physics, will be kept cool using LEWA diaphragm metering pumps. The specially modified LEWA pumps will constantly feed liquid carbon dioxide (CO2) into the detectors’ cooling circuit at temperatures as low as -55 °C.
In accordance with EU Directive 2024/3190, a Europe-wide ban on the use of bisphenol A (BPA) and its derivatives took effect on January 20, 2025. This decree applies to all industrial companies that produce, market or use materials that come into contact with food.
The Hydraulic Institute introduces member company, Kirloskar Brothers Limited (KBL), as the latest company to have their pump test laboratory, located at Kirloskarvadi, Maharashtra approved through the HI Pump Test Lab Approval Program.
