Piston pumps and motors have been on the market for many years, and they are arguably one of the most important components in many hydraulic circuits. The basic design behind a conventional piston pump usually has seven or nine pistons that convert mechanical torque into oil pressure. In a piston motor, the process is reversed. […]
Valve technology for enhanced control
Innovative application-specific valve concepts are one of the most important requirements for boosting productivity in mobile hydraulic applications, according to the engineers at Bucher Hydraulics, Remscheid, Germany. The company’s new modular SC12 proportional directional valve system, for example, offers responsive control behavior and low operating costs with consistently high machine availability. At the same time, […]
Mobile hydraulics gets an unwelcome jolt
One unmistakable take-away from this year’s bauma show was the buzz surrounding electrification. The idea of massive mobile machines running only on batteries may seem far-fetched, but for smaller equipment it has become a reality. At every turn, major manufacturers like Cat, Kobelco, Komatsu and Volvo to niche players like Ecovolve and Giant featured electrified […]
Bucher Hydraulics announces “revolutionary” new pump design
The performance of traditional hydraulic pumps has not kept up with increasingly stringent customer demands and new application requirements, according to officials at Bucher Hydraulics, Klettgau, Germany. They’re tackling such concerns with a new design for piston pumps and motors called the AX series. The AX is not an evolutionary improvement over existing products, said […]
Electrification exposes hydraulic-pump shortcomings
Heightened concerns over climate change and global warming are key reasons for the growing interest in zero-emission vehicles. Battery-electric mobile machines, while still mainly in the prototype stage, may require hydraulic-pumps and variable-speed drives to evolve to suit future applications. Hydraulic pumps are high-performance components. However, according to engineers at Bucher Hydraulics, Klettgau, Germany, they […]
Safe and reliable control of large flows
The CINDY family of cartridge valves from Bucher Hydraulics, Klettgau, Germany, has been proven for decades in countless industrial and mobile applications. That, according to company officials, is due to features such as extremely low leakage, finger-tip controllability and load-independent cylinder travel behavior. Bucher Hydraulics has now expanded its well-established CINDY technology offerings with the […]
Cartridge directional valves feature internal monitoring
Based on tried and tested cartridge-type directional seat valves, Bucher Hydraulics has developed a comprehensive valve family with a reliable system for monitoring operating position. The modular design reportedly lets users create individualized systems using high-performance valves that meet extreme requirements in mobile and industrial hydraulics—whether the focus is on energy efficiency, power density, intelligence […]
Bucher offers mini power pack
Engineers at Bucher Hydraulics have developed the UP40 mini power pack with the aim of bringing hydraulic control closer to the drive while providing a more-compact envelope. Compared to other products on the market, the UP40’s dimensions have been reduced to a minimum, said company officials. The external dimensions of 80 × 80 mm (3.15 […]
Bucher flow dividers offer higher precision
With a deviation of just 1.5%, new flow dividers from Bucher Hydraulics, Klettgau, Germany, offer higher precision compared to their more-conventional counterparts. The new versions complement an extensive product family of the company’s MT series of flow dividers. These automatically operating units split a volume flow into two part-flows that can vary within certain limits. […]
Bucher safety valves deliver energy savings
Safety valves are critical for protecting equipment and personnel. And, according to officials at Bucher Hydraulics, Neuheim, Switzerland, they can also play a major role in the global competitiveness of mobile machines like cranes and excavators when the focus is on high performance and availability. The company offers an extensive portfolio of safety valves that […]
