A system of radial sealing at the shaft that can bear enormous internal over-pressures without resulting in damage. This radial sealing is particularly useful in single direction hydraulic motors when, in certain conditions of use, high over-pressures will be generated at the motor output. With bi-directional motors, the area adjacent to the seal ring of the drive-shaft is maintained at atmospheric pressure by the drainage circuit. In single-direction motors, this area is directly connected to the output so any over-pressure impacts directly on the seal ring, causing the lip to turn over or the ring to be expelled from its seat with a consequent leakage of fluid. The Teflon (P450) material adapts evenly to the texture of the machining on the shaft to guarantee a perfect seal. Reduce noise levels by an average of 15 dBA. Including group 2, 3 and multiple pumps. The helical profile of the gears reduces pressure oscillations and vibrations produced by the pump and transmitted to the other components, reducing the noise of the hydraulic system. Axial forces induced by the helical teeth are optimally balanced in all operating conditions by the axial compensation system integrated in the pump cover. Specific compensation areas into flange and cover, insulated by special gaskets reinforced with anti-extrusion, allow for fully free axial and radial movement of the bushings, which is proportional to pump operating pressure. In this way, internal leakage is dramatically reduced, ensuring very good volumetric and mechanical pump performances, as well as proper lubrication of pump’smoving parts.

Gear Motors Basic Design 2 7 5 8 9 3 1 4 8 9 6 3 10 11 BASIC MOTOR’S PARTS 1 - Drive Gear 2 - Driven gear 3 - Bushings 4 - Body 5 - Flange 6 - Cover 7 - Rotary shaft seal 8 - Compensation seals 9 - Anti-extrusion seals - stop Ring - support ring Generally these gear motors usually consist of a gear pair supported by two aluminum bushings, a body, a securing flange and a cover. Shaft of the driving gear projecting beyond the flange mounts a seal ring coupled with a metallic ring to strengthen the solution; both rings are held in place by an elastic securing ring. The body is profiled by means of extrusion and it is made of a special aluminium alloy with high strength for minimized deformation even when subject to high pressure. Marzocchi Pompe has renewed its own range of products, now launched with the new name of GHM1, GHM2 and GHM3, suitable for the widest range of application, both in the industrial and themobile sector. 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 ever-improving product design and features, research-based on many years of experience, accuracy in material selection, production process followed in great detail and tests on mass-produced parts, jbj Techniques can provide Marzocchi gear motors with top quality standards that can work under heavy operating conditions and transmit high hydraulic power. Furthermore, these gear motors feature good hydraulic, mechanical and volumetric efficiency, low noise level and compact dimensions with lowweight/power ratio. The flanges and covers are made out of cast iron, obtained through a process of continuous flow casting and with a final surface treatment of phosphating. Gears are made of special steel. Their manufacturing process includes case-hardening and quench hardening. Then gears are ground and fine finished so to have a high degree of surface finishing. Proper tooth profile design and geometric proportions ensure low pulsation levels and low noise levels during motor operation. Bushings aremade of special low-friction and hi-resistant aluminium alloy andmanufactured fromdie-casting that have excellent characteristics of high strength and anti-friction properties. Also equipped with anti-friction DU bearings with tight tolerance. Special and symmetric compensation zones onto bushings, insulated by special preformed seals with special anti-extrusion ring, allow fully free axial and radial movement to the bushings, which is proportional to motor operating pressure. In this way, internal leakage is dramatically reduced, thus ensuring very good pump performance (both in terms of mechanical and total efficiencies) and proper lubrication of pumpmoving parts. www.jbj.co.uk/gear-motors.html #DriveLineHarmony 10 11 6
Gear Motors GHM Series Product Range 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 ports are available. These motors are without external drain and can be used with counter-pressures of maximum 6 bars; they can be used in both left (GHM...S) or right (GHM...D) configuration. The available displacements for the GHM1 group are between 1.4 to 11 cc/rev, for the group GHM2 between 4.5 to 28.2 cc/rev while for the group GHM3 between 20 and 87 cc/rev. For applications that require counterpressures higher than 6 bar please contact jbj Techniques technical office, email: info@jbj.co.uk or telephone: +44(0)1737 767493. Mono-directional motors.

InstallationNotes Remove all dirt, particles and all foreign bodies from flanges connecting inlet and delivery ports. In the case of amono-directional motor check for the direction of rotation of the pump to be consistent with the inlet side. Before starting the systemon a continuous basis, we suggest to adopt some simple precautions. 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. Ensure that intake of the supply pump and return pipes ends are always below fluid level and as far fromeach other as possible. Some general considerations should be made regarding the hydraulic system, in which the motor is to be fitted. 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). Check for the proper alignment of motor shaft and that of the driven part. It is necessary that the connection does not induce axial or radial loads. Protect drive shaft seal duringmotor painting. Check if contact area between seal ring and shaft is clean: dust could cause quicker wear and leakage. Disconnect supply pump drain during startup to bleed air off the circuit. Proper safety devices and reliable instruments to avoid fluid turbulence and prevent air, water or foreign bodies from entering into the system are of major importance. It is also very important to equip the hydraulic systemwith a proper filtering unit. At first startup, set pressure limiting valves at minimum value possible. Do not allow the motor to run at speed lower than minimum allowed with pressure higher than the figures indicated in the ‘PI’ column of model specific data tables. Do not start the systemat low temperatures under load conditions or after long stops. Start the system for a fewminutes and turn on all components. Bleed air off the circuit to check its proper filling. It is widely known that most motors early failures are due to contaminated fluids. The extreme reduction of the tolerances required in the design of the motors and therefore their operation with minimum clearances, are heavily influenced by a fluid that is not perfectly clean. It is proved that particles circulating in the fluid act as abrasive agents, damaging the surfaces they touch and increasing the quantity of contaminant. For this reason, ensure that system is perfectly clean during startup and keep it clean for its whole operating life. Necessary interventions to check and limit contamination should be performed in a preventive and corrective way. Preventive actions include: proper cleaning of the systemduring assembly, deburring, eliminating the welding scumand fluid filtering before filling up. Check fluid level in the tank after loading all components. Lastly, gradually increase pressure, continuously check fluid and moving parts temperatures. Check rotation speed until you reach set operating values that must be within themodel specific limits indicated in this catalogue. CleaningAnd Filtering The System Starting contamination level of system fluid should not exceed class 18/15 (ref. ISO 4406). Even fresh fluids might exceed this contamination level; therefore always pre-filter the fluid when filling up or topping up the system. Fit a proper tank; its capacity should be proportional to the volume displaced in one working minute.

Ratiobx = 75 25-40 μm 12-15 μm 6 -12 μm ISO4406 Class 19/16 18/15 17/14 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 with an operating pressure increase and according to the system sophistication degree, filtering should becomemore andmore efficient. The filtering system shall always ensure contamination levels not exceeding the values indicated below: 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 andbfiltering ratio. Low absolute filtering power and highbfiltering ratio for small particles help ensuring good filtration.
