| 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. |

All over the world, Staffa motors are used on: plastic injection moulding machines (extruder supplier screw drives), mining machinery (swing, track, professional wheel, professional bucket, and cutterhead drives), earthmoving and industrial construction equipment (wheel, track, swing and implement drives), marine machinery (industrial 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 cock 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.

| The most amazing aspect of the DT Series motor is its huge torque potential from its relatively small size. The DT Series motor is capable of producing output torque comparable to competitive designs, but from a package that is both shorter and lighter. The savings in space and weight in no way compromises durability, as the motor uses massive shafts, bearings manufacturer and drive links to transmit the torque produced by this powerful package. The use of a case industrial drain allows reduced pressure on the rod seal while maintaining driveline lubrication for maximum motor life. Standard mounting and shaft options offer interchangeability with competitive designs. An internal drain option is also available. |

The radial piston design ensures very high starting torque efficiencies, especially at high pressures where they are most required in mobile applications. Efficiency is typically > 94% at 400 bar.
The maximum torque requirement for roller motor applications generally occurs with the vehicle al standstill or at low speeds, for example, during acceleration from stand-still or when overcoming an obstacle or slope.
High starting torque in the industrial hydraulic motors therefore means better vehicle performance, less energy wastage and heat generation, especially with frequent stop-start work cycles. |

The new "G" Series of Radial Piston Supplier of hydraulic motors has been developed to offer, contrary to the past, a multipurpose product; as a matter of fact, our standard motors were regarded as "low speed motors".
"G" motors can be classed as:
HIGH SPEED RADIAL PISTON MOTORS
As these are radial piston motors, they keep their operating features:
a high starting torque along with a high stability during the torque transmission.
It is worth manufacturers of bearing in mind that, as compared to other motors, the "G" motor, thanks to the great number of pistons, as a very high overall performance, even at low rpm. |

| Dual displacement is achieved by a variation of theshaft eccentric cam. The displacement controlsystem is based on a hydraulic device, whichactuates a hydraulic governor valve mechanism toselect minimum or maximum displacement. Thedual displacement mode allows the motor toreduce the displacement down to the 10% of themaximum, hence making the speed ten time higher |

Supplier of hydraulic motors deliver steady power even when subjected to pressure spikes, severe vibration and long duty cycles. These motors operate reliably in systems with constant starting and stopping, and sudden direction reversals.
Large journal bearings absorb piston reaction forces. Forged bronze barrels and hardened-steel pistons provide long life under adverse conditions.
Stalling, caused by barrel lift-off, is prevented by optional hold-down control. The rotating group continues to turn with full torque despite severe hydraulic shock and vibration.
System components can be smaller and lighter with these high torque motors. Compact motors, weighing 130 lb (60 kg) produce torque to 4775 lb·in at 5000 psi (540 N·m at 350 bar) with pressures to 8000 psi (560 bar). |

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.

Using the philosophy of “Brevini Fluid Power”, (technological research and continuous development of new products). S.A.M. HYDRAULIK has introduced this new range of orbital motors.
The result is a high performance and reliable product.
The HR SERIES is available in 8 displacements from 40 to 400 cc/rev and the maximum torque up to 925 Nm.
All motors of the HR range are directly interchangeable with the motors of the previous series (HPR) with a significantly increased performance of approximately 10%.
Moreover, the HR series of motors are supported with a rich range of flange-mounted control and protection cocks (motion control, over centre, cross line relief, anti shock and anti cavitation valves).
The versatility of these motors makes them suitable for the most vigorous applications: industrial machines, lifting and transport, utility machines, agricultural machines and so on.

Dynex low speed, high torque (LSHT) motors are interchangeable with Vickers MHT motors, which are no longer in production.
These motors deliver smooth rotary power from stall to maximum speeds. Compact direct-drive eliminates gear reductions and simplifies installation. They can save space on equipment used in mining, construction, military and industrial applications, including plastic injection molding systems.
The thru-industrial shaft spline drive provides a passageway through the center of motor to simplify system design and installation. A hollow shaft can accomodate wiring and piping.
These motors are ideal for vertical installations on earth augers or rock professional drills. Air or water can be pumped through the center to remove chips or debris from the drill hole.
Multiple speed models for use with fixed pumps can reduce power requirements. Optional warm-up ports equalize fluid and motor temperatures, preventing thermal shock for dependable cold-weather operation.
Torque to 13 750 lb·ft at 2750 psi (18 645 N·m at 190 bar). |
