Bucher Industrial Hydraulic Equipment and Systems

Internal gear pumps and pump-motors Series QX, QXEH, QXV, QXM

Bucher Hydraulics QX and QXEH series internal gear pumps are engineered for high-pressure machine tool drives, injection molding machinery, metal forming presses and heavy mobile hydraulic systems operating up to 400 bar.

The hydrostatically compensated design and proprietary tooth profile deliver exceptionally low noise levels from 58 dBA with minimal flow ripple across full speed ranges.

The specialized QXV line is specifically configured for metering and pumping low-viscosity fluids including polyols, isocyanates, polyurethane components and HFA/HFB/HFC fire-resistant media.

QXM pump-motors deliver four-quadrant operation for energy-efficient variable-speed servo drives with outstanding volumetric efficiency.

Specify displacement (1.0 to 500 cc/rev), operating pressure, shaft type (SAE/DIN), fluid viscosity and multi-stage configuration.

External gear pumps and motors Series AP05, AP100, AP212, AP300

Bucher Hydraulics AP series external gear pumps and motors feature rugged aluminum alloy and cast iron body constructions for mobile equipment, forklift trucks, municipal utility vehicles and industrial power stations.

Precision 12-tooth gears combined with floating axial thrust plates maintain volumetric efficiencies up to 96% at continuous operating pressures up to 280 bar. The range encompasses AP05/AP100 micro-pumps, versatile AP212 medium-duty units and AP300 high-flow pumps.

Multi-stage tandem configurations with through-drive shafts and reversible APM gear motors deliver long-lasting durability in demanding duty cycles.

Specify displacement (0.25 to 73 cc/rev), mounting flange (European, SAE, DIN), shaft profile and direction of rotation.

Proportional directional control valves Series LVS08, LVS12, LVS16

Bucher Hydraulics LVS proportional directional control valves provide load-independent multi-actuator motion control through individual Load-Sensing compensators in each working slice.

The modular block architecture accommodates up to 10 working sections with flow capacities up to 180 l/min at system pressures up to 350 bar. Actuation options include 12V/24V PWM proportional solenoids, hydraulic pilot signals and manual mechanical levers.

Each valve slice integrates individual shock and anti-cavitation valves to safeguard mobile booms, winches and rotary drives from excessive pressure peaks.

Specify valve size (LVS08, LVS12, LVS16), section count, flow per section, solenoid voltage and spool circuit configuration.

Sectional and monoblock directional spool valves Series HDS11, HDS15, HDS20, HDS34

Bucher Hydraulics HDS directional control valves are manufactured in monoblock and sectional configurations for truck cranes, excavators, wheel loaders and municipal utility chassis.

High-grade spheroidal graphite cast iron bodies withstand peak cyclical shocks up to 320 bar with flow ratings from 40 to 250 l/min.

Slices integrate anti-cavitation check valves, secondary relief valves, mechanical detents, cable actuators, pneumatic pilots and on/off solenoids with parallel, series and tandem internal fluid circuitry.

Specify series (HDS11, HDS15, HDS20, HDS24, HDS30, HDS34), slice count, spool diagram and actuation type.

Screw-in hydraulic cartridge valves and manifolds DBV, RV, DRV, CBE, W1, WE

Bucher Hydraulics screw-in cartridge valves install into industry-standard SAE cavity ports (SAE-08 through SAE-20) and metric manifold cavity forms.

The portfolio includes direct-acting and pilot-operated pressure relief valves DBV, pressure reducing valves DRV, check valves RV, counterbalance/overcentre valves CBE and directional solenoid cartridges W1/W2/WE rated up to 450 bar and 500 l/min.

Every cartridge undergoes 100% factory seat leakage testing for absolute reliability in compact manifolds.

Specify cartridge type, cavity standard (SAE-08 to 20), pressure adjustment range, coil voltage and inline body options.

Compact hydraulic power packs and micro units Series UP, M, D

Bucher Hydraulics UP, M and D series compact power packs integrate DC electric motors (12V/24V up to 3 kW) or AC motors (230V/400V up to 7.5 kW), precision gear pumps, fluid reservoirs from 0.5 to 60 liters and custom valve manifold blocks into pre-assembled units.

They power vehicle tail lifts, scissor lift tables, automotive lifts, compact balers, industrial machine tools and electrohydraulic medical equipment with minimal installation space requirements.

Specify motor voltage/power, pump delivery, reservoir volume, hydraulic manifold circuit and duty cycle rating.

Elevator hydraulic control valves and drive systems Series LRV-1, VF-LRV, iValve

Bucher Hydraulics LRV-1, VF-LRV and iValve electronically controlled elevator valve systems deliver ride comfort and millimetric levelling precision for passenger, panoramic and freight hydraulic lifts.

The VF-LRV variable-frequency drive reduces electrical consumption by up to 30% while eliminating oil overheating during peak building traffic.

The digital iValve controller continuously tunes cabin acceleration curves with ±3 mm stopping accuracy regardless of car payload or fluid temperature variations.

Specify elevator payload, travel speed, maximum flow rate (up to 700 l/min), power pack rating and CANopen interface.
