Axial piston units are available in the form of pumps and motors in bent axis design or swashplate design for medium- and high-pressure ranges. They are the main components in the hydrostatic transmission. Compact size and high power density, economy and reliability are characteristic advantages which speak for the use of hydrostatic transmissions, together with the fact that they meet the demand for high speed and high torque, as well as optimum efficiency.

Black Bruin motors are at their best in situations where high torque is required and use of other transmission is not reasonable. Hydraulic transmission does not contain axles allowing the frame structure to provide e.g. higher ground clearance and sharper wheel turn angle.
Starting is soft and motion is smooth even at low speed. On the other hand, vehicles equipped with multi speed Black Bruin motors are capable of reaching top speed exceeding 70 km/h.
The motors are used e.g. as wheel hub motors for agricultural, forestry, road building and mining machines.
Black Bruin BBC hydraulic motors
• excellent efficiency at high speeds - in both directions
• high pressure level (450bar)
• mechanical freewheeling
• broader speed range than conventional models
• higher load capacity in smaller size
• variety of mounting options for accessories
• multiple brake options

External gear units are classic hydraulic units and come in the form of pumps and motors. Individual pumps, multiple pumps and lownoise SILENCE versions in seven different series open up a virtually unlimited range of possible uses.

All over the world, Staffa motors are used on: plastic injection moulding machines (extruder screw drives), mining machinery (swing, track, wheel, bucket, and cutterhead drives), earthmoving and construction equipment (wheel, track, swing and implement drives), marine machinery (winch and steering mechanisms), and forestry machines (swing and cutterhead drives) as well as many others.
Staffa motors are offered in models that include single displacement, dual displacement and continuously variable forms supplemented by integral gearboxes, brakes, and standard valve packages.
Staffa motors offer consistent, controlled acceleration of loads and smooth, steady, low speed operation. Moving parts are immersed in hydraulic fluid, so Staffa motors do not require periodic lubrication.
They also save money by increasing usable drive power and reducing drive train maintenance.

GM - Crankshaft design radial piston hydraulic motors
GM series motors are a result of the many years' of experience gained with the preceding M, L and P series motors, and incorporate a number of design variations with respect to these series intended to increase the strength of the motor casings and the load capacity of the internal dynamic components. The result is a series of motors with high continuous power ratings, both because of the reduced internal specific loads and because of the high mechanical and volumetric efficiency that contribute in reducing the amount of heat produced and therefore also the negative effects associated with it.
