In the energy sector, Bucher Hydraulics develops solutions and products for wind energy as well as hydraulic valves, drive modules, and hydraulic drive systems for high-voltage circuit breaker applications.
As the only independent supplier, we offer a wide range of customized hydraulic solutions for high-voltage circuit breaker applications to 1,200 kV. Bucher Hydraulics solutions are based on well proven technology, which has been in operation in high-voltage circuit breakers for 50 years all over the world.
For 50 years, Bucher Hydraulics has been developing and manufacturing:
for high-voltage circuit breaker applications.
The product range of Bucher Hydraulics includes single pumps 05-100-212-212HP-250HP-312HP (corresponding with the common group denominations: 05-1-2-2.5-3) and several combinations of double pumps, triple pumps, and so on, that can be assembled together according to versions of displacement, flanging, and auxiliary valves.
The CBKA gear pump consists of a gear pair supported by two aluminum bearing blocks, a housing, front cover and rear cover. The axis clearance can be automatically compensated by the bearing blocks. The CBKA pumps' features are high mechanical a-nd volumetric efficiency, low noise level as well as low weigh/power ratio.
The QX series is the 5th generation of Bucher's internal gear pumps and has proven itself for decades in the mobile and industrial hydraulics markets. Many aspects of the design have been enhanced, and it is characterized by a simple layout with relatively few components. It is exceptionally compact and robust. As a direct result of the special gear profile that Bucher uses, QX pumps achieve extremely low levels of pulsation and noise emission, even at high pressures and speeds. Thanks to the wide range of variants, QX pumps can be used for virtually all applications.
The QXEH series has been specially developed for pumping duties in highly dynamic servo drives with a reversing function. Using the pinion-shaft technology, high pressures up to 280 bar are developed in a single stage. QXEH pumps are therefore particularly well suited for a wide range of applications in industrial hydraulics where there are high demands on power density, energy efficiency and machine productivity. At the same time, they ensure maximum operational reliability coupled with minimal flow- and pressure-pulsations even during operation with highly dynamic load cycles.
The QXEHX series is the successor to the QXEH series, and brings new advantages with it. In addition to optimized hydrodynamic lubrication, the speed range has now been extended up to 5000 rpm. With increased power density and improved operational reliability, this surpasses even the benefits offered by the QXEH series. This makes QXEHX pumps particularly suitable for downsizing the entire drive train, e.g. in injection molding and die casting machines, while at the same time achieving a long service life.
The QXV series has been developed for use with low-viscosity fluids. QXV pumps have proven particularly successful in applications for pumping kerosene, automotive fuels, paraffin, brake fluids and many other low-viscosity fluids. When required, a multi-stage pressure build-up can be employed to achieve high pressures of up to 250 bar with a viscosity close to 1 mm2/s, and with high efficiencies at the same time.
The QXP series has been specially developed for metering and conveying the fluids used in polyurethane production. Thanks to the hydrodynamic and hydrostatic bearing support for the ring gear, the pump can be operated with low, as well as with very high, viscosities, and at low speeds. QXP pumps are therefore particularly suitable for variable-speed drives with exacting requirements for precision metering. In addition, the enlarged sealing surfaces enable high efficiencies to be achieved.
The QXEM series is intended for operation as both a pump and a motor. A symmetrical design makes these units specially suitable for highly dynamic variable-speed multi-quadrant operation. In the industrial hydraulics field, they are therefore particularly appropriate for applications with highly cyclical loading. Thanks to the pinion-shaft technology, pressures up to 250 bar are built up in a single-stage. The direction of rotation can also be reversed in milliseconds, while maximum operational reliability is ensured at all times thanks to optimized hydrodynamic lubrication.
AX is the innovative piston pump series, designed and industrialized to match newest requirements of electric machines with variable speed drives. The AX piston pump is available in different sizes with displacement ranges form 18 to 122 cc and with single, two or four quadrant operation. Various combinations with tandem pumps are possible as well.
The essential components of series APM212 external gear motors are an aluminium alloy body and two gearwheels supported by plain bearings. The front flange can be the SAE standard, or the British or German OEM patterns. Particular attention has been focussed on the design of the shaft seal, which is often affected by back-pressures.
The QXM-HS (High Speed) internal-gear motor was developed specifically for use at extremely high speeds. Its first-rate efficiency and extremely low noise levels also make a significant contribution to reducing the costs of both energy and anti-noise measures.
Thanks to the special motor flange, adapted for such applications, and the integral ports for auxiliary functions, the motor can be used in many applications without needing any further modification.
The QXM-Mobil internal gear motor was specifically developed for use in mobile applications. Its outstanding efficiency and extremely low noise levels also make a significant contribution to reducing the costs of both energy and anti-noise measures. The QXM design principle, featuring an integral outboard bearing, ensures top-class protection against leakage at the shaft seal.
Boom cylinders are used for moving the boom and stick. These cylinders are the largest in our product range. They are up to 3500 mm in length when extended and weigh almost 600 kg.
Swing-axle cylinders are used for locking the swing axle in mobile construction machines. Our swing-axle cylinders feature a strong and stable design with integral lock valves. Thanks to this compact design, complex routing of hydraulic lines is unnecessary. The cylinder can be controlled with just one line.
Stabiliser cylinders are safety-related components that are subjected to enormous loads. Our cylinders fulfil the exacting requirements relating to functionality, compact design, long service life and, of course, safety-related design.
The dozer blade is an attachment on mobile excavators. The dozer blade is also used as a support to improve the stability of the excavator. Two hydraulic cylinders bring the blade into the support position. Integral check valves provide leak-free shut-off and offer pipe rupture protection. In a similar manner, when the dozer blade is in the raised position a check valve prevents it from sinking.
Suspension cylinders are used for hydro-pneumatic chassis suspension on mobile cranes. The extending piston rod is an area that is exposed to many demands, and it is protected by a gaiter.
Counterweight cylinders are used to hold the counterweight on mobile cranes. Appropriate process planning ensures the safety standard for this cylinder during manufacturing and assembly.
Locking or bolting cylinders are safety devices on cranes. They are used to bolt the boom extension or the main boom. The necessary bolts are integrated in the design of our cylinders.
Our steering cylinders are used in the hydraulic steering system of various vehicles such as cargo/material handlers, for example. Thanks to our efficient manufacturing, you get an inexpensive, long-lasting product.
Our brake cylinders are used in the hydraulic brakes of various vehicles, for example as wheel brake cylinders.
Our spring actuators are mainly used in parking and service brake systems in a very wide variety of vehicle types. The active work is done by the integral compression spring and the brake is released hydraulically or pneumatically. The compression springs used are fatigue resistant and treated to ensure optimum corrosion protection.
Lift and tilt cylinders are used to move the bucket in wheel loaders. These cylinders are subjected to high dynamic loads and therefore need to be designed and built for extremely heavy-duty service.
Our gripper cylinders are used in two- and multi-tine grabs for material handlers. These cylinders feature the robust and fail-safe design that the harsh application requires. The piston rods used are induction hardened and, where needed, the cylinders are equipped with cushions.
Quick-hitch cylinders are incorporated in the steelwork of the attachment-change devices on wheel loaders. They bolt and unbolt the attachment. The heavy-duty design ensures a long service life
Hydraulic counterbalances are used in industrial robots. The job of the closed system is to counteract the axis load-moment sufficiently that the axis drive is not statically overloaded and can provide maximum torque for the acceleration of the axis. The function of the closed gas volume in the diaphragm accumulator is comparable to that of a mechanical spring.
Steering lock cylinders are special designs for locking steered axles on construction machines. Our products range from spring actuators with pneumatic override to steering rods with hydraulic unlock for mobile cranes.
Our tool-changer cylinders are used in modern CNC machine tools. A long service life is essential for this application.
Mobile cranes are usually brought into their working position with four ground stabiliser cylinders. It is important to provide the greatest possible stability. The cylinders must be designed for high loads and shear forces. As is fitting for this application, we use high-strength materials and take care to ensure the greatest precision. The stability of the cylinder is ensured by incorporating leak-free lock valves in the head of the cylinder.
Hydraulic backstop cylinders are used on lattice boom cranes as a hydraulic means for preventing the boom from toppling backwards. In the final position of the jib (almost vertical), the cylinder is forcibly in-stroked and thereby builds up the necessary pressure to push the jib back again. They are therefore Category A safety components. A cylinder failure would result in the crane overturning. To accommodate the enormous mechanical forces, our hydro-storage cylinders are manufactured exclusively from high-strength steels.
Bucher Hydraulics electro-pumps series ET are equipped with modern external gear pumps - AP05, AP100 and AP212 series together with efficient DC or AC electro-motors. These electro-pumps offer high volumetric efficiency and mechanical characteristics, good balancing and therefore reduced noise and vibration.
In Bucher Hydraulics ET project development, simplified architectures and reduced dimensions were the main goals to be achieved. For this purpose the housings of these pumps can be equipped with valves and hydraulics circuits.

Closed servo-hydraulic axes combine the advantages of an electric servo drive with those of a robust, powerful and efficient hydraulic transmission.
In Systems Engineering, project methods are used to design client-specific solutions in the form of manifold control blocks. These are mainly used in mobile equipment for agriculture and municipal services, in road-building and construction machines, as well as in renewable energy systems such as wind turbines or solar power plants. The manifold blocks, in steel or aluminium design, offer maximum functionality in a very small space.
Monoblock designsValve combinations in monoblock construction consist of a single, heavy-duty, cast body that is designed for high working pressures. Thanks to the wide selections of spools, types of operators, types of hand levers, and auxiliary valves such as secondary pressure relief, anti-cavitation make-up, pressure control, flow control and check, these are particularly suited for use in complex applications where small installation dimensions are vitally important.
Custom solutions are often based on new developments and require close cooperation between the development department and the customer. This calls for direct contact between the customer and the Competence Center.
