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 Pumps Basic Design BASIC PUMP 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 Marzocchi Pompe has further developed its own range of products with a new series of pumps named GHP where groups named GHP1, GHP2 and GHP3 suitable for the widest range of application, both in the industrial and themobile sector. Bushings are made of special low-friction and hi-resistant aluminum alloy and manufactured from die-casting. Besides they are equipped with antifriction DU bearings. Special compensation zones onto bushings, insulated by special preformed seals with anti-extrusion ring, allow fully free axial and radial movement to the bushes, which is proportional to pump operating pressure. In this way, internal dripping is dramatically reduced, thus ensuring very good pump performance (both in terms of volume and in general) and proper lubrication of pumpmoving parts. The body of the pump is made of special hi-resistant aluminum alloy obtained through extrusion process, while flange and cover are made out of spheroidal cast iron; this in order to ensure minimized deformation even when subject to high pressure, be it continuous or intermittent or peak pressure. 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 pump operation. External gear pumps are the most popular pumps used in modern hydraulic systems. They feature versatility, strength and long useful life. Their simple construction 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 onmass-produced parts, our gear pumps have reached top quality standards. For this reason, our products can work under heavy operating conditions and transmit high hydraulic power. Furthermore, these gear pumps feature good hydraulic, mechanical and volumetric efficiency, low noise level and, last but not least, compact dimensions. Generally these gear pumps usually consist of a gear pair supported by two aluminum bushes, a body, a securing flange and a cover. Shaft of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal and the outer being a dust seal). An elastic securing ring secures the ring in place. www.jbj.co.uk/gear-pumps.html #DriveLineHarmony 10 6 2 7 5 8 9 3 1 4 8 9 6 3 10

Disconnect pump drain during startup to bleed air off the circuit. Start the system for a fewminutes and turn on all components; bleed air off the circuit to check its proper filling. Some general considerations should be made regarding the hydraulic system, in which the pump 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). It is essential for correct running, top performance and longer life of the GHP series hydraulic gear pumps to follow the installation and running information provided in this catalogue. Check for the direction of rotation of the pump to be consistent with the drive shaft one (in case of single rotation pump). InstallationNotes Protect drive shaft seal during pump painting. Check if contact area between seal ring and shaft is clean: dust could cause quicker wear and leakage. 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. Remove all dirt, particles and all foreign bodies from flanges connecting inlet and delivery ports. Ensure that intake and return pipes ends are always below fluid level and as far fromeach other as possible. Before starting the systemon a continuous basis, we suggest to adopt some simple precautions. Install the pump below head if possible. Fill the pump with fluid, and turn it by hand. At first startup, set pressure limiting valves at min. value possible. Check for the proper alignment of pump shaft. It is necessary that the connection does not induce axial or radial loads. Avoid lower rotation speed thanmin. allowed with pressure higher than P1. Do not start the systemat low temperatures under load conditions or after long stops (always avoid or limit load starting for pump longer life). Check fluid level in the tank after loading all components. At last, gradually increase pressure, continuously check fluid and moving parts temperature, check rotation speed until you reach set operating values that shall be within the limits indicated in this catalogue. CleaningAnd Filtering The System It is widely known that most pump early failures are due to contaminated fluids. The extreme reduction of the tolerances required in the design of the pumps, 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. Regular checks should be made for contamination of the oil. Preventive actions include: proper cleaning of the system during assembly, deburring, eliminating the welding scumand fluid filtering before filling up. Starting contamination level of system fluid should not exceed class 18/15 (ref. ISO 4406). Even fresh fluids might exceed this contamination level; therefore For this reason, ensure that system is perfectly clean during startup and keep it clean for its whole operating life. Gear Pumps GHP Series Installation and Running Information 8 www.jbj.co.uk/gear-pumps.html #DriveLineHarmony
Gear Pumps GHP Series Installation and Running Information 9 www.jbj.co.uk/gear-pumps.html #DriveLineHarmony 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. Fluid contamination levels should be monitored by use of correct filter types. Two parameters tell which filter is most suitable: absolute filtering power andb filtering ratio. Low absolute filtering power and highbfiltering ratio for small particles help ensuring good filtration. It is then very important to limit not only the size of particulate, 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: Pressure <140 bar 140 to 210 bar >210 bar NAS 1638 Class 10 9 8 ISO4406 Class 19/16 18/15 17/14 Ratiobx = 75 25-40 μm 12-15 μm 6 -12 μm It is recommended to use a filtering systemhaving absolute filtering capability of 5 μmor lower in the systems using sophisticated valve slaves.

Direction of Rotation The GHP series gear pumps are available as single directional and bi-directional. The direction of rotation is defined in the following way: looking at the front of the pump with the driver shaft positioned upward and sticking toward the observer, it will be a mono-directional right "D". GHP...D pump therefore with right. "D" rotation, if its rotation will be clockwise and therefore the inlet port will be on the left while the outlet port will be on the right. Vice-versa it will be a monodirectional left GHP...S therefore with left "S" rotation when looking at it from the same angle.. S = counter-clockwise rotation INPUT OUTPUT D = clockwise rotation INPUT OUTPUT R = reversible rotation The bi-directional GHP series pumps, "R" have both functional characteristics of the mono-directional motors with clockwise and counterclockwise rotation. Connect the pump to the motor using a mechanical power transmission coupling so that no radial and/or axial force is transmitted to the pump shaft during rotation, otherwise pump efficiency will dramatically drop due to early wear of inner moving parts. 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. Calculate the velocity (v) of a fluid in a pipe as follows: v =Q / 6 •A[m/s] Frequently Used Formulas Drive For further details contact jbj Techniques technical office, email: info@jbj.co.uk or telephone: +44 (0)1737 767493 In case of axial and/or radial loads on themotor’s shaft T option is available for some GHP2models and RAoption is available for some GHP1 types. Fluid velocity A= inside area of pipe [cm²] Absorbed flow rate V = displacement [cm³/rotation] hvol = pump volumetric efficiency (take 0.95 as an indicative value for rotation speeds ranging between 1000 and 2000 rotations per minute) Calculate flow rate (Q) as follows: Absorbed torque Q= flow rate [litre/min] Q= V • n • 10 -3 / hvol [litre/min] n = rotation speed [rotations per minute] Calculate necessary torque (M) of a pump subject to pressure differential between inlet and delivery as follows: V = displacement [cm³/rotation] M= (V •Dp) / (62.8 • hhm) [Nm] Dp = pressure differential [bar] hhm= hydromechanical efficiency (take 0.80 as indicative value under cold conditions and 0.85 under working conditions).

Gear Pumps GHP Series Information 12 Once the pump flow rate has been selected, different flanges, shafts, inlet and outlet port position and type are available to suit most applications. In the product tables, the flow, shown at 1500 rpm, has been evaluated using a value of volumetric efficiency of 95%. All the drawings represent pumps with clockwise rotation. Reversing the direction of rotation also involves reversing of the suction side with the delivery side ports. The following diagrams show, for each single displacement, the typical required power as a function of rotation speed and pressure generated by the system and allow you to easily spot the product suitable for your application. Calculate hydraulic power (P), delivered by amotor subject to a pressure differential between input and output as follows: Dp = pressure differential [bar] Q= flow rate [litre/min.] Apump requires energy, just like any other hydraulic machine. Part of this power is given to the fluid to increase pressure required by the circuit, the remaining part is used to cure pump internal friction. Therefore, for proper pump operation, supplied torque shall be higher than theoretical torque. P= (Q •Dp) / (600 •htot) [kW] htot = total pump efficiency (hhm •hvol) Contact jbj Techniques technical office, email: info@jbj.co.uk or telephone: +44 (0)1737 767493 for further details on efficiency. The proper values for flow rate, torque and supplied according to pressure differential, rotation speed and set test conditions, can be found on thePerformance Curvepages. These pumps are hydraulic machines converting mechanical power into hydraulic power. This section deals with rotary positive-displacement pumps. In this type of pump, a given volume of fluid flows from inlet to outlet at each shaft rotation (theoretical displacement). Pressure depends on delivery line resistance to fluid flow. As gear pumps only transfer fluid, they are subject to pressure generated by the circuit. Therefore, if system flow rate and motor rotation speed are known, it is easy to select the right pump displacement and its model. Absorbed power Values for hvol andhhm (and consequentlyhtot) depend on pressure differential between supply and delivery, rotation speed, fluid features (temperature and viscosity) and filtering degree. The diagram indicating flow rate variations according to speed and pressure, shows that not all the theoretically available fluid is transferred from inlet to outlet because of pump internal leakage.
