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.

an excellence in engineering www.jbj.co.uk/ .html FTP-gear-pumps Marzocchi FTP pumps are based on ELIKA Gear Technology that reduces the noise level by an average of 15 dBA compared with a conventional external gear pump. The helical gears ensure the continuity of motion despite the low number of teeth. FTP pumps are perfectly interchangeable with standard gear pumps. The low number of teeth reduces the fundamental frequencies of the pump noise, therefore lowering sound levels. The shape of the Elika profile, patented by Marzocchi Pompe, eliminates the encapsulation phenomenon typical of standard gear pumps, remedying the source of themain cause of noise and vibrations. By reducing the pressure-oscillations and vibrations produced by the pump and transmitted to the other components, the noise of the hydraulic system itself is reduced. Specific compensation areas in the flange and cover, insulated by special gaskets reinforced with anti-extrusion, allow for fully free axial and radial movement of the bushings. Ideal for low-pressure, low viscosity, lubrication applications such as fire-resistant fluids. The FTP gear pump fromMarzocchi is an ideal solution for low-pressure lubrication applications where low-viscosity fluids are required, such as fireresistant fluids. Typical applications include large lubrication systems, lubrication of the guides of machine tools, and the lubrication and cooling of tools themselves. Fire-resistant fluids are used whenever there is a possibility that a hydraulic fluid (also used for lubrication) may encounter a source of ignition, such as the surface of very hot equipment. Fire-resistant hydraulic fluids are specially formulated so they are more difficult to ignite and do not propagate a flame froman ignition source. There are several types of fire-resistant fluids and they are generally classified as follows: oil and water emulsions, water-polymer solutions, and anhydrous synthetics. More specifically, the International Standards Organization (ISO) further classifies these fluids as follows: HFAE – oil-in-water emulsions, typically with more than 80%water content; HFAS – synthetic aqueous fluids, typically with more than 80%water content; HFB – water-inoil emulsions, typically with more than 40%water content; HFC – water polymer solutions, typically with more than 35%water content (also known as glycol solutions, polyalkylene glycol solutions or water glycols); HFDR – synthetic anhydrous fluids composed of phosphate esters; and HFDU – synthetic anhydrous fluids other than phosphate esters. Examples include polyol esters and polyalkylene glycols. The only fire-resistant fluids that are completely incompatible with gear pumps are the HFDR ones; for all the others, it is possible to obtain a configuration that makes them compatible. To avoid fast wear of the sliding contact parts, FTP pumps can be supplied, depending on the type of application with bronze or bronze/PTFE thrust plates. These FTP helical gear pumps are available in versions with or without a relief valve built into the cover, and maximum working pressure is 50 bar. The gear pumps have very high specifications for rotation speed and viscosity range. FTPpumps are available in clockwise rotation whilst a counter-clockwise rotation version is currently under development. www.jbj.co.uk/ftp-gear-pumps.html

Pump shaft alignment is key to preventing unnecessary wear and damage to the pump shaft seal and bearing. Improper alignment may lead to premature pump failure. Also to be considered are unwanted torsional resonant frequencies in the system which can quickly cause damage to components in the drivetrain and reduce system life and performance. Improper pump installation can lead to premature failure, increased maintenance costs and reduced production levels of final product. jbj Techniques can advise on the correct installation of into Industrial / hydraulic pumps mobile / marine / machine tool / agricultural / offshore industries and can specify complete driveline systems from their extensive range of components which are available from stock or manufactured to order, albeit simple or complex, standard or bespoke.

Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). 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. With a vast array of components to select from, jbj are well placed to provide all required components to support the required cooling system.
