widely used, peristaltic pump platform for demanding duties. In lithium processing, they provide the reliable, repeatable transfer needed for sodium carbonate addition and lithium brine handling, helping operators protect recovery, maintain product consistency and reduce maintenance through a simple, fully contained design with strong control flexibility.”


The resulT Watson-Marlow 630 pumps and Qdos chemical metering pumps have helped GEL to achieve: • Accurate dosing of acids and alkalis • Reliable dosing and transfer of lithium brine at high temperatures, and sodium carbonate


• Safer, fully contained chemical handling • Consistent lithium recovery and product grade • Easy maintenance and rapid tube changes • Familiar hardware for operators The company also benefits from local support

valves for high power hydraulic systems


Two valves for NG16 / CETOP 07 applications have been launched by Domin, extending its technology into higher flow applications up to 580 l/min (153 gpm). High-power hydraulic systems sit at the


heart of industrial processing, energy, and test environments, where downtime and supply delays don’t just slow things down. The S12 Pro and P12 Pro are designed to address that challenge head-on. S12 Pro offers fast response, stable


control under heavy load, and consistent behaviour at high flow and pressure. This is aimed at demanding use cases like test rigs, large presses, turbines, and motion platforms, where control quality and speed are essential to system performance. P12 Pro offers reliability and ease


of integration in industrial production environments. It combines predictable servo proportional behaviour with strong dynamic response. Both valves are engineered to maintain


control quality over time, reducing performance degradation, extending service intervals, cutting maintenance burden, and improving overall system productivity.

digital hydraulic architecture helps reduce excavator power consumption


Danfoss Scotland has announced the results of its Dextreme Max system validation in a 30-tonne battery-electric excavator. It demonstrated that its Dextreme digital hydraulic architecture reduced excavator power consumption by 35% across a representative duty cycle mix, corresponding to 53% longer runtime on a single charge. Danfoss’ Dextreme Max system aims to cut


excavator energy consumption by up to 50% by reducing energy losses and recovering energy that would otherwise be wasted. The system’s integral component is the DDP1X0D, a Digital Displacement hydraulic pump/motor with multiple independently controlled outlets. The Dextreme Max system provides independent actuator supply, eliminates flow- sharing losses, and enables energy recovery from excavator motions such as boom lowering. Danfoss selected a Develon DX300LC-7 crawler


excavator for the project, supplied in an electric configuration by Staad B.V., The engine was replaced with an electric drivetrain consisting of a Danfoss Editron EM-PMI375 permanent magnet synchronous motor, EC-C1200 inverter, and MC050 motor controller, plus three 140-kWh batteries. Danfoss engineers replaced the excavator’s


conventional swashplate hydraulic pump with the DDP180D pump/motor. The excavator’s four


primary services – boom, arm, bucket, and swing – are supplied through ten individually controllable outlets on the pump. These outlets are dynamically grouped through a ganging block, a digital distributor that reallocates capacity to the service requiring it. A dedicated valve operating as a hydraulic H-bridge was applied to the boom function to allow independent metering, providing anti-cavitation, pressure amplification, and energy recovery during overrunning motions. Finally, the control system architecture was developed to provide real-time control of the hydraulic system, electric powertrain, and auxiliary subsystems. Compared to the baseline


electric excavator, the Dextreme Max system reduced battery energy use by 49.2% in air grading and 31% in air dig and dump, with negligible impact on cycle time. Assuming a duty cycle of 30% grading and 70% digging, Dextreme Max would reduce battery power consumption by 35% without significantly impacting work rate. “The results of this testing highlight the potential


of digital hydraulic architectures to overcome the obstacles in heavy-duty machinery electrification,” said Alasdair Robertson, senior director, Digital Displacement, Danfoss Power Solutions.
