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.
Finish Thompson Inc. (FTI) highlights the VKC Series vertical pumps for chemical processing and industrial fluid handling applications. The VKC Series integrates a sealless mag-drive vertical design with an airtight column, helping to prevent shaft and motor corrosion while reducing environmental emissions and fugitive leaks. The magnetic drive eliminates the need for wetted shaft bearings, enhancing reliability and minimizing maintenance costs.
PSB Industries is proud to highlight its Oxygen and Moisture Removal system designed for natural gas, landfill gas, wastewater treatment plant gas, and dairy gas applications. Engineered to optimize product quality and reliability, the turnkey Deoxo-Dryer packages utilize a precious metal catalyst operated at elevated temperatures to eliminate oxygen from methane gas.
The scale of the challenges for innovation has never been greater in the UK water sector – that was the message from the Innovation Summit jointly hosted by British Water and Bentley Systems in the City of London on 30 September 2025.
Valmet has received an order to deliver a comprehensive replacement of plant DCS and turbine control systems at the Ennatuurlijk’s combined cycle power plant (CCPP) in Helmond, the Netherlands. The modernization project will enhance the plant’s operational efficiency, reliability, and safety, while ensuring stable combined heat and power (CHP) production. The project also supports the company’s long-term commitment to achieving carbon neutrality.
Tackling leakage is one of the fastest and most cost-effective ways for utilities to bolster water security, writes Ben Crabtree, product line director, Ovarro, revealing how the potential of smart technologies is being demonstrated around the world.
Electric motors are everywhere, found in industrial equipment, fans, pumps, compressors, heating and air conditioning systems, and many more. And yet, much of the energy in typical motors is dissipated as heat, friction, and design inefficiency. Energy efficient motors aim to make a difference: they convert more of the electrical energy into useful mechanical power, reducing energy consumption, slashing operating expenses, and shrinking environmental footprints.
Anglian Water has completed the installation of specialist wastewater treatment equipment from WCS Environmental Engineering (WCSEE). A total of 10 WCSEE Hybrid modular biological treatment units and two Flocell XFMs for tertiary solids removal were put in place as part of a major upgrade of Horning Knackers Wood water recycling centre (WRC) in north Norfolk.
After six years of anticipation, AchemAsia, the International Expo and Innovation Forum for Sustainable Chemical Production, has returned with a renewed spirit, bringing together global expertise, Chinese innovation, and a shared commitment to a greener industrial future. That is the conclusion of the organisers of AchemAsia.
LEWA has added two new model sizes to its range of micro-metering pumps to offer a wider choice of flow and pressure combinations, enabling more effective and cost-efficient gas odorization.
The Wilo Group has once again won the German Sustainability Award (DNP). The jury selected the multinational water technology group as the winner for the ‘Hydraulics, Pumps and Compressors’ industry, recognising, among other things, Wilo’s holistic focus on sustainable innovation.
