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.

They feature versatility, strength and long useful life. Their simple construction ensures limited purchase costs and servicing. 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 on mass-produced parts, our gear pumps have reached top quality standards. 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. 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. Bushings are made of special low-friction and hi-resistant aluminium alloy and manufactured from die-casting. They are equipped with antifriction DU bearings (except forALP1 pumps). Pump body is aluminiumprofiled by means of extrusion. Micro-pumps andALP series models feature high-tensile aluminumalloy flange and covers, whereas GHP models have globular cast iron flange and covers. These materials minimize part deformation even when subject to continuous, intermittent and peak high pressure values. Special compensation zones onto bushings, insulated by special preformed seals with anti-extrusion ring, allow fully free axial and radial movement to the bushings, 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 pump moving parts. Marzocchi Pompe has introduced a splined drive system between the elements of amodular multiple pump. Shaft profile is splined by rolling, whereas the steel splined joint is a result of precision casting. Thanks to an accurate system design and precise setting of connecting part clearances, offsets occurring in assembled modular stages can be compensated still ensuring high power. Multiple pump stages can be easily installed, aligned and sealed through the use of a centring ringmade out of two pieces of different materials. This catalogues describes some models of modular stages belonging to the newALP and GHP series. These gear pumps consist of a pair of gears supported by two aluminumbushes, a body, a flange and a cover. www.jbj.co.uk/gear-pumps.html #DriveLineHarmony 10 11 6 2 7 5 8 9 3 1 4 8 9 6 3 10

Fill the pump with fluid, and turn it by hand. » the torque value transmitted by the first stage shaft is the total of the torque values transmitted by each single stage. Before starting the systemon a continuous basis, we suggest to adopt some simple precautions. 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. Ensure that intake and return pipes ends are always below fluid level and as far fromeach other as possible. When possible, refer to the indications given on single stage catalogues for ALP, GHP and micro-pump series to set torque values as absorbed by each pump stage. Max. torque value applicable to the primary drive of the front stage of a modular multiple pump is specified in the overview table in the catalogue forALP and GHP series. Max. torque values applicable to the secondary shafts of middle and/or back stages are the following: Disconnect pump drain during startup to bleed air off the circuit. Avoid lower rotation speed thanmin. allowed with pressure higher than P1. »max. rotation speed is the lowest rotation speed amongmax. rotation speeds of each stage. Remove all dirt, particles and all foreign bodies from flanges connecting inlet and delivery ports. »operating pressures are limited by max. torque values which can be transmitted by the shaft of the first stage and the shaft connecting one or more stages. Max. Torque 18 Nm 18 Nm 50 Nm 100 Nm 220 Nm 550 Nm Check for the proper alignment of pump shaft andmotor shaft. It is necessary that the connection does not induce axial or radial loads. In the case of amono-directional motor check for the direction of rotation of the pump to be consistent with the drive shaft (in case of single rotation pump). InstallationNotes Install the pump below head if possible. At first startup, set pressure limiting valves at min. value possible. Group 0.25 0.5 ALP, GHP1 ALP, GHP2 ALP, GHP3 ALP4 Do not start the systemat low temperatures under load conditions or after long stops (always avoid or limit load starting for pump longer life). Start the system for a fewminutes and turn on all components; bleed air off the circuit to check its proper filling. 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. It is essential for correct running, top performance and longer life of hydraulic gear pumps to follow the installation and running information provided in this catalogue. 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). 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. »ensure that power absorbed by the front stage is higher than or equal to the power absorbed by the back stage in two-stage pumps or the middle parts in three-stage pumps or pumps featuringmore stages. For correct use of Marzocchi modular pumps, please comply with the following: Gear Pumps ALP-GHP Series Installation and Running Information 8 www.jbj.co.uk/gear-pumps.html #DriveLineHarmony
Pressure <140 bar 140 to 210 bar >210 bar 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. 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. For this reason, ensure that system is perfectly clean during startup and keep it clean for its whole operating life. 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 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 andbfiltering 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: NAS 1638 Class 10 9 8 ISO4406 Class 19/16 18/15 17/14 Hydraulic Fluids Use specific mineral oil based hydraulic fluids of good anti-wear, anti-foaming (rapid deaeration), antioxidant, anti-corrosion and lubricating properties. Fluids should also comply with DIN 51525 and VDMA24317 standards and compliant with 11th stage of FZG test. Fluid kinematic viscosity ranges are of following: allowed value (upon verification) 6 to 500 cSt For the standardmodels, the temperature of the fluid should be between -10°C and +80°C. If fluids other than the above mentioned type are used, please always indicate type of used fluid and operating conditions so that jbj Techniques technical office can advise of possible problems with compatibility or useful life of systemparts. Intake line 0.5 to 1.6m/s Hydraulic systempipes should show no sudden changes of direction, sharp bends and sudden differences in cross-section. They should not be too long or out of proportion. Pipe cross-section should be sized so that fluid velocity does not exceed recommended values. It is advisable to carefully consider the possible diameter reduction of the inlet or outlet pipes fitted on flange fittings. Delivery line 2 to 6m/s Under standard working conditions, intake pipe pressure is lower than atmospheric pressure. The operating inlet pressure should range between 0.7 and 3 bars (absolute). recommended value 10 to 100 cSt Inlet &Delivery Lines value allowed at startup <2000 cSt Inlet Pressure Return line 1.6 to 3m/s Gear Pumps ALP-GHP Series Installation and Running Information 9 www.jbj.co.uk/gear-pumps.html #DriveLineHarmony

Direction of rotation of single rotation pumps is conventionally defined as follows: when standing before the pump with driving shaft up with its projecting end towards the observer, the pump is rotating clockwise in case of right-hand rotation "D"; therefore, delivery side is on the right, whereas intake side is on the left. The contrary will happen with left-hand pumps "S", keeping the same point of view. The above applies only to front and back stages. Middle stages have no direction of rotation of their own as it is set by the way they are assembled to the front or back stage. Always refer to the direction of the arrow on the pump body to clearly determine the delivery side of a middle stage, and therefore its direction of rotation. Direction of Rotation S = counter-clockwise rotation INPUT OUTPUT D = clockwise rotation INPUT OUTPUT R = reversible rotation
Calculate flow rate (Q) as follows: In case of driving through gears, pulleys or chains, the T option is recommended. This option allow radial and/or axial loads on the pump shaft. Calculate hydraulic power (P), transferred to fluid froma pump subject to a pressure differential between inlet and delivery as follows: Drive 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. Absorbed power Dp = pressure differential [bar] Calculate the velocity (v) of a fluid in a pipe as follows: V = displacement [cm³/rotation] A= inside area of pipe [cm²] v =Q / 6 •A[m/s] Calculate necessary torque (M) of a pump subject to pressure differential between inlet and delivery as follows: Frequently Used Formulas Q= V • n • 10 -3 / hvol [litre/min] n = rotation speed [rotations per minute] V = displacement [cm³/rotation] Q= flow rate [litre/min] hvol = pump volumetric efficiency (take 0.95 as an indicative value for rotation speeds ranging between 1000 and 2000 rotations per minute) M= (V •Dp) / (62.8 • hhm) [Nm] For further details contact jbj Techniques technical office, email: info@jbj.co.uk or telephone: +44 (0)1737 767493 Fluid velocity Absorbed flow rate Dp = pressure differential [bar] Absorbed torque hhm= hydromechanical efficiency (take 0.80 as indicative value under cold conditions and 0.85 under working conditions). Q= flow rate [litre/min.] 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 Values for hvol andhhm (and consequentlyhtot) depend on pressure differential between supply and delivery, rotation speed, fluid features (temperature and viscosity) and filtering degree.

Gear Pumps ALP-GHP Series Information 13 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. Leakage can be greatly reduced through pressure axial compensating systems (as described at the beginning of this catalogue) but never eliminated. Leakage increases as circuit pressure increases. 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. 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. 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. 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. www.jbj.co.uk/gear-pumps.html #DriveLineHarmony
