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 al l operat ing condi t ions 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. The package consists of a bellhousing and flexible drive coupling that are fully machined to suit the pump and any driving interface; diesel or petrol engine, electric or hydraulic motor. jbj's in-house design team and manufacturing faci l i ty provide tai lored solut ions for your applications at competitive prices with quick delivery.

Gear Pumps Basic Design 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 duty operating conditions and transmit high hydraulic power. Furthermore, these hydraulic gear pumps feature good hydraulic, mechanical and volumetric efficiency, low noise level and, last but not least, compact dimensions and lowweight/power ratio. Marzocchi Pompe thus specialized their production in low-power oil-operated pumps for auxiliary services. This product is called 1P and it is widely used in power units. 0.25 and 0.5 micro gear pumps usually consists 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. Pump body, flange and cover are made of special hi-resistant aluminum alloys for minimized deformation even when subject to high pressure, be it continuous or intermittent or peak pressure. The body is profiled by means of extrusion, whereas flange and cover are obtained by means of die-casting or gravity casting. 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 aluminum alloy and manufactured from die-casting. They are equipped with antifriction DU bearings (except for ALP1 pumps). Special compensation zones onto bushings, insulated by special preformed seals with antiextrusion ring, allow fully free axial and radial movement to the bushings, which is proportional to pump operating pressure. In this way, internal dripping is 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 10 6 www.jbj.co.uk/gear-pumps.html #DriveLineHarmony 1 9 8 6 3 4 2 3 9 8 5 7 10
Marzocchi gear micropumps are available in two different groups: 0.25 and 0.5, they differ only for the tooth profile. Different pump displacements within each group can be obtained by changing the thickness of the gear toothed band. Within the same group, different flanges, shafts, inlet and pressure ports are available. The following items are also available: - micropumps suitable for high pressure applications; - bi-rotational micropumps; - micropumps with check valves; - modular multiplemicropumps.

It is essential for correct running, top performance and longer life of the ALP series 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. InstallationNotes Before starting the systemon a continuous basis, we suggest to adopt some simple precautions. 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). Check for the proper alignment of pump shaft andmotor shaft. It is necessary that the connection does not induce axial or radial loads. 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. 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. Install the pump below head if possible. Fill the pump with fluid, and turn it by hand. Disconnect pump drain during startup to bleed air off the circuit. At first startup, set pressure limiting valves at min. value possible. 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). 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. 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 Gear Pumps Micro Series Installation and Running Information 8 www.jbj.co.uk/gear-pumps.html #DriveLineHarmony
Gear Pumps Micro Series Installation and Running Information 9 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 and b filtering ratio. Low absolute filtering power and high b filtering 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 Ratio bx = 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. 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. For the standardmodels, the temperature of the fluid should be between -10°C and +80°C. Fluid kinematic viscosity ranges are of following: allowed value (upon verification) 6 to 500 cSt recommended value 10 to 100 cSt value allowed at startup <2000 cSt 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. Inlet Pressure 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). In case the pump must work with higher pressure in the intake pipe, a special “TR” version is available.

Supply &Delivery Lines 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. Reference values are the following: Intake line 0.5 to 1.6m/s Delivery line 2 to 6m/s Return line 1.6 to 3m/s
Direction of Rotation The P1 series gear pumps are available as single rotation and bi-rotational. 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". ALP...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 ALP...S therefore with left "S" rotation when looking at it from the same angle.. S = counter-clockwise rotation D = clockwise rotation R = reversible rotation The bi-rotational Micro series pumps, "R" have both functional characteristics of the mono-directional motors with clockwise and counterclockwise rotation. 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. 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.

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 the Performance Curve pages. 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. 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. 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. 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. 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 D Group Rotation Size Ports* Special Versions 0.25 0.5 Clockwise S Counter Clockwise R Reversible Shaft* 18 24 30 Ordering Code tang tapered* C G - KK KA KX KE V High temperature ST Special temperature TR Reinforced shaft seal Pressure relief valve not mounted - mounted** VM ...

www.jbj.co.uk/gear-pumps.html #DriveLineHarmony 27 Micro Hydraulic Gear Pumps Single Reversible Pumps As described at the beginning of the single rotation micro pump section, also bi-rotational models are rotary positive-displacement micro pumps with external gears. Their operating concept is the same as single rotation pumps. What changes is that bi-rotational pumps can rotate both clockwise and counterclockwise thanks to their perfectly symmetrical machining on the internal components. Some models have the external drain positioned on the flange or on the cover; connection pipes to the system tank should never be clogged or show reduced cross-section, otherwise pressure values might exceed 6 bar. The bi-rotational micro pump is capable of handling pressurized inflow. Please contact jbj Techniques technical department, email: info@jbj.co.uk or telephone: +44 (0)1737 767493 for system operating conditions other than indicated in the product tables.
