Basic Design MARZOCCHIPOMPE BASIC MOTOR’S PARTS 2 - Driven gear 3 - Bushings 4 - Body 5 - Flange 6 - Cover 7 - Rotary shaft seal 8 - Compensation seals 9 - Anti-extrusion seals 10 - stop Ring 11 - support ring Gear motors convert hydraulic pressure and flow into torque and angular displacement, rotary mechanical power, applied to a load via the shaft. They feature versatility, strength and long useful life. Their simple construction compared to other types of motors (piston, orbital, etc) ensures limited purchase costs and servicing. Thanks to these basic concepts, together with...

Gear Motors GHM Series Product RangeMARZOCCHIPOMPE Bi-directional motors. Produced in three different groups with very good power/weight ratio and power/size ratio allowing a wide range of displacements within each group (between 2.8 and 87 cc/rev). The wide range of allowed speeds, the excellent functionality also on their use in series, with strong counter-pressures and limited drain, give to motors of the GHM series very good characteristics even starting under load. The drain is always external and it is through a thread port on the cover. Arange of flanges, shafts, inlet and pressure...

Gear Motors GHM Series Installation and Running InformationMARZOCCHIPOMPE It is essential for correct running, top performance and longer life of the GHM series hydraulic gear motors to follow the installation and running information provided in this catalogue. Some general considerations should be made regarding the hydraulic system, in which the motor is to befitted. Special attention should be given to hydraulic system design and assembly, especially to intake, delivery, return and drain pipes and position of system parts (valves, filters, tanks, heat exchangers and accumulators). Proper...

Gear Motors GHM Series Installation and Running InformationMARZOCCHIPOMPE Fluid contamination level check and correction during operation can be obtained through filters that retain the particles present in the fluid itself. Two parameters tell which filter is most suitable: absolute filtering power and p filtering ratio. Low absolute filtering power and high p filtering ratio for small particles help ensuring good filtration. It is then very important to limit not only maximum dimensions, but also the number of smaller particles that pass through the filter. It goes without saying that...

Gear Motors GHM Series Installation and Running Information MARZOCCHIPOMPE Pressure Definition Product tables show three max. pressure levels (PC, PI and PP) to which each motor can be used. PC = max pressure continually as output counterpressure. PI = max inlet pressure continually. PP = max peak inlet pressure. The value of the maximum continuous PI pressure can be reached only if the following ranges of rotation are not overcome. The motors of the GHM series can be supplied both in mono-directional version and bi-directional. The direction of rotation is defined in the following way:...

Gear Motors GHM Series Installation and Running InformationMARZOCCHIPOMPE Drive The link between the motor and the driven device must be via a mechanical power transmission coupling that will not transfer radial and/or axial thrust to the shaft of the motor otherwise wear of the internal components will quickly occur, jbj Techniques have a wide range of suitable couplings to suit a wide range of applications and we can advise on which coupling depending on the circumstances of the application. In case of axial and/or radial loads on the motor’s shaft T option is available for some GHM2...
