Low Noise, Low Pulsation Gear Motor Applications www.jbj.co.uk/gear-motors.html #DriveLineHarmony IV The low noise, high efficiency, low pulsation, helical gear motor. Up to 20 dBA noise reduction. ® Marzocchi Elika Motors are built on patented ELIKA Gear Technology, which reduces noise levels by an average of 15 dBA compared to conventional external gear pumps. The use of helical gears ensures smooth, continuous motion even with a reduced number of teeth. This lower tooth count shifts the pump’s fundamental noise frequencies, resulting in a quieter and more pleasant sound profile. The distinctive Elika Profile, patented by Marzocchi Pompe, eliminates the encapsulation phenomenon common in standard gear pumps—removing one of the primary sources of noise and vibration. By minimizing pressure oscillations and vibration transmission to surrounding components, Elika technology significantly lowers the overall noise of the hydraulic system. Additionally, specially designed compensation zones in the flange and cover, insulated by anti-extrusion reinforced gaskets, enable free axial and radial movement of the bushings, further enhancing performance and durability.
® Low Noise, Low Pulsation Gear Motor Elika Groups www.jbj.co.uk/gear-motors.html #DriveLineHarmony 1 New Energy Sources Medical Equipment Industrial Sector The ELIKA series stands out for its low noise and low ripple characteristics, making it an ideal choice for a wide range of applications. Thanks to its advanced technical specifications, ELIKA motors can significantly enhance the overall performance of the circuits in which they are installed. ELIKA motors are particularly well-suited for industrial applications, including presses, machine tools, testing equipment, paper processing machines, waste compactors, and recirculation pumps. Additionally, with increasingly strict regulations in the mobile sector, ELIKA offers an optimal solution for material handling systems, lifting platforms, street-cleaning vehicles, and urban waste collection equipment. The ELIKA series also excels in the naval, shipbuilding, and leisure sectors, as well as in renewable energy applications, where efficiency and low noise emissions are critical. Thanks to their broad operating speed range, ELIKA motors are ideal for use in variable-speed drive systems. In such systems, a fixed-flow pump like ELIKA can replace a variable-flow pump when paired with an inverter—leading to significant cost savings. Furthermore, integrating ELIKA into variable-speed systems greatly reduces acoustic emissions and vibrations, enhancing operator comfort—particularly in high-performance, noise-sensitive applications.

Some general considerations should be made on the hydraulic sys-tem, in which the motor must be fitted. Special attention shall be devoted to hydraulic system design and assembly, especially to intake, delivery and return pipes and position of system parts (valves, filters, tanks, heat exchangers and accumulators). Proper safety devices and reliable instruments to avoid fluid turbulence, especially in return pipe to the tank, and prevent air, water and foreign bodies from entering into the system are of major importance. It is also very important to equip the hydraulic system with a proper filtering unit. Before starting the system on a continuous basis, we suggest to adopt some simple precautions: » Check for the direction of rotation of the motor to be consistent with the drive shaft of the prime mover. » Check for the proper alignment of pump shaft and motor shaft: it is necessary that the connection does not induce axial or radial loads. » Protect drive shaft seal during motor painting. Check if contact area between seal ring and shaft is clean: dust could provoke quicker wear and leakage. » Remove all dirt, chips and all foreign bodies from flanges connect-ing inlet and delivery ports. Ensure that intake and return pipes are always below fluid level and as far from each other as possible. » Install the motor below head, if possible. » Fill the motor with fluid, and turn it by hand. » At first startup, set pressure limiting valves at min. value possible. » Avoid lower rotation speed than min. allowed with pressure higher than P1. » Do not start the system at low temperatures under load conditions or after long stops (always avoid or limit load starting for motor longer life. Start the system for a few minutes and turn on all components; bleed air off the circuit its proper filling. » Check fluid level in the tank after loading all components. » Finally, 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. Cleaning and filtering the system 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 the 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 system during assembly, deburring, eliminating the welding scum and fluid filtering before filling up. Starting contamination level of system fluid should not exceed ISO class 20/18/15 (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 by the pump in one working minute. Fluid contamination level check and correction during operation can be obtained through filters that retain the particles in the fluid. Two parameters tell which filter is most suitable: absolute filtering power and β filtering ratio. Low absolute filtering power and high β filtering ratio for small particles help ensuring good filtration. It is then very important to limit not only max 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 Low Noise, Low Pulsation Gear Motor Installation Notes #DriveLineHarmony 18 PRESSURE Nas 1638 Class ISO 4406 Class Ratio βx = 75 < 140 BAR 10 21/19/16 25 - 40 μm 140 - 210 BAR 9 20/18/15 12 - 15 μm > 210 BAR 8 19/17/14 6 - 12 μm www.jbj.co.uk/gear-motors.html
Low Noise, Low Pulsation Gear Motor Installation Notes #DriveLineHarmony 19 Hydraulic fluids Use specific mineral oil based hydraulic fluids having good anti-wear, anti-foaming (rapid de-aeration), antioxidant, anti-corrosion and lubricating proprieties. Fluids should also comply with DIN 51524 and VDMA 24317 standards and get through 11 stage of FZG test ISO 14635- 1. For the standard models, the temperature of the fluid should be between -10°C and +80°C. Fluid kinematic viscosity ranges to be found in the table A15. If fluids other than the above mentioned ones are used, please always indicate type of used fluid and operating conditions so that our technical sales engineering department can weigh possible problems on compatibility or useful life of system parts. Direction of rotation Marzocchi ELIKA series motors are available in either clockwise or counter-clockwise rotation. Direction of rotation of single rotation motors is conventionally defined as follows: when standing before the pump with driving shaft up with is 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-handed motors "S", keeping the same point of view. The ELIKA motors can not be modified in order to reverse the work rotation direction. Seals "N" Standard version on NBR the temperature of the fluid should be between -10°C and +80°C. "V" Fluorocarbon version suitable for fluid at hi- temperatures. Range between –10°C and +120°C. In the range between –10°C and +80°C pressures P1, P2, and P3 are possible as per product table; beside that P1 should not be exceeded. Frequently Used Formulas: Fluid Velocity: v = Q / 6 x A [m/s] Q = flow rate [litre/min] 2 A = inside area of pipe [cm ] Absorbed flow rate: 3 Q=V·n·10 / ηvol [l/min] 3 V = displacement [cm /rotation] n = rotation speed [rpm] ηvol = pump volumetric efficiency (take 0.97 as an indicative value for rotation speeds ranging between 1000 and 2000 rpm) Delivered torque: M = (V · ΔP · ηhm) / 62.8 [Nm] 3 V = displacement [cm /rotation] ΔP = pressure differential [bar] ηhm = hydromechanical efficiency (take 0.80 as indicative value under cold conditions and 0.85 under working conditions) Delivered power P = (Q · ΔP · ηtot) / 600 Q = flow rate [litre/min] ΔP = pressure differential [bar] ηtot = total pump efficiency (ηhm x ηvol) Values for ηvol and ηhm (and consequently ηtot) depend on pressure differential between inlet and delivery, rotation speed, fluid features (temperature and viscosity) and filtering degree.

An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level.
