Hydraulic Power Units

Hydraulic Power Units are normally designed accordingly to customer specification, in order to meet oil delivery, pressure and dimensional limits requirements.

Standard and silenced HPU are equipped with Bosch Rexroth pumps and can be connected tank-to-tank for parallel working; in the table here below their main charachteristics.

Hydraulic servocylinders

Conceived for dynamic position/force actuation, our cylinders can be designed in different technologies according to application requirements:

hydrostatic servocylinder with pressurized oil pocket bearings (negligible friction, side-load admissible).
hydrodynamic servocylinders with autolubricated bushes (negligible friction, side-load admissible).
hydrodynamic servocylinders (negligible friction, side-load not-admissible).
industrial cylinder (robust and suitable for harsh environment).

All kind of cylinders can be equipped with servovalve on-board, load cell and position transducer (analogue, SSI, LVDT).

Working fluids:

mineral oil according to DIN 51524
military standard MIL-PRF-5606 /-83282 /-87257
Skydrol for civil aviation

Electro-magnetic linear motors

Linear motors are synchronous permanent magnet electric actuators, their negligible friction and high-stiffness allow an high-fidelity actuation in position/force closed-loop control, particularly suitable to apply small forces, approx. < 1000 N, with speed rate ranging from very low to very high.

Typical application: aeronautics/automotive test benches for pilot simulation (stick and pedal actuation).

HSM Manifold and customized hydraulic blocks

HSM Manifold is a common solution for testing application, here below their main features:

OFF: no flow – no pressure; LOW: Max flow – low pressure; HIGH: Max flow – Max pressure
control by means of two 24VDC-30W digital commands.
pressurization and unload ramp time can be adjusted manually, in order to have a soft start/stop
available size: HSM50 (50 l/min) ; HSM100 (100 l/min) ; HSM200 (200 l/min) ; HSM400 (400 l/min) ; HSM800 (800 l/min)
