Hydraulic piston pumps are the current standard for power, control and efficiency, but such a position in the hierarchy comes with more significant investment and responsibility. Piston pumps are expensive, complicated and involved compared to their lessor counterparts, such as the venerable gear pump. Inexpensive piston pumps still start in the four-figure range, and once…

The global agricultural machinery and supplier industry will be on show at Agritechnica from November 12 to 18, demonstrating inspiration and solutions for the complex challenges of global crop production under the motto “green productivity.” Finnish hydraulic motor manufacturer Black Bruin is proud to be part of this with sustainable innovations to be showcased on […]

By Josh Cosford, Contributing Editor Before I begin, let me preface this article with my definition of “electrified.” It’s rarer to find a hydraulic machine with no electrical or electronic components, so electrified might be redundant. In this case, I’m discussing the motion control and automation side of hydraulics, where the electric more is more […]

By Robert J. Sheaf, Founder CFC Industrial A new hydraulic power unit was duplicated to replace a 30-year-old conveyer system unit. It was installed, ran fine at start-up and ran for about four weeks. However, when the customer shut the unit down for more than 10 minutes or so, it would make loud noises when…

Hydraulic motors are rotary actuators that convert hydraulic energy into mechanical torque. Using the pressure and flow provided by the hydraulic pump, hydraulic motors rotate to pull, drive or winch external loads on various hydraulic machines spanning construction equipment to food mixers. The three most common constructions of hydraulic motors are the gear, vane and […]

The Moog EPS expands the existing portfolio of electrohydrostatic components and drive systems with a modular and energy-efficient drive solution with a high degree of freedom for users and operators. The Electrohydrostatic Pump System (EPS) consists of an Electrohydrostatic Pump Unit (EPU) and a standardized manifold…

Updated September 6, 2023 with the solution By Robert J. Sheaf, Founder CFC Industrial The attached circuit was a standard and is still used by some manufacturers that build concrete trucks. It is a simple and inexpensive circuit compared to the latest technology available using pressure-compensated, load-sensing pumps and pressure filters on the charge pump…

Adding shuttles to axial piston pumps can substantially increase overall efficiency. Peter Achten, Robin Mommers and Jeroen Potma • INNAS BV, Breda, The Netherlands Given today’s push to limit global warming and embrace a carbon-neutral future, there is a heightened focus on improving the efficiency of industrial and mobile equipment and their underlying fluid power…

Mobile hydraulics is often called on for tough forestry jobs, and Diamond Mowers’ new Belt Drive Disc Mulcher is suited for contractors and mulching professionals who specialize in land clearing, vegetation and forestry management, and pasture reclamation. It features increased torque to obliterate anything in its path without slowing down, recovers twice as fast as […]

During its more than 60-year-long history, Finnish-based Black Bruin has delivered innumerable hydraulic drive solutions to manufacturers of forestry equipment and their end users, loggers and contractors all around the world. These highly durable and energy-efficient solutions will be showcased on stand N:03d at the Swedish Forestry Expo from June 1-3, 2023. Equipment used in […]

The Pump & Motor Division Europe of Parker Hannifin has announced the launch of its new disengageable twin flow truck pump, the F4 series, as an innovation for the mobile hydraulics market. The new F4 hydraulic pump merges technology from the successful F2 twin flow pump and F3 axial piston fixed pump series, resulting in […]

As it highlighted its system options along with its technologies for electrification at IFPE last month, Bosch Rexroth showcased new and legacy products that can optimize modern machines. One such component was its A36VM axial piston variable motor, which was developed specifically for hydrostatic drivetrains. It allows greater tractive force and speed for mobile machines. […]

Hägglunds has won the Spotlight On New Technology Award from the Offshore Technology Conference (OTC 2023) for the Atom motor, which is the world’s most compact powerful gearless drive that can be used to convert electric energy or diesel power to rotary motion.
