Parker Releases Conversion Kits For CCV Solutions

The Racor division of Parker Hannifin has extended its range of crankcase-ventilation (CCV) solutions with new conversion kits and fittings. Two conversion kits are available, which enable a CCV8000 assembly to be converted to a CCV12000 model, improving the filtration of harmful exhaust gases at minimum cost. To simplify the installation of the latest CCV products, Parker has developed 90deg fitting adaptors, which allow hoses to be connected to the crankcase filter quickly and easily.

By installing one of the Parker Racor CCV55613-08 and CCV55613-10 conversion kits, users can increase the filter media of a CCV8000 system by 60 per cent, effectively turning it into a CCV12000 assembly. This makes it simple and affordable to achieve extra capacity in engines that are not easily accessible. Like all Parker Racor CCV systems, the kits are compact and durable, combining coalescence and crankcase-pressure control. The kits are easy to install, especially when used with Parker Racor 90deg fitting adaptors.

These components allow CCV assemblies to be installed in tighter applications, where using a straight barbed fitting may be difficult. Hoses can be routed vertically to the crankcase filter and, once in place, can be locked in any orientation. Added benefits include reduced oil consumption and extended service life for turbos and aftercoolers, minimising maintenance requirements and cutting operating costs for end users.

Parker Hydraulic Hoses Minimise Maintenance

Parker Hannifin has launched three hydraulic hoses, developed to minimise maintenance and increase profitability across a range of industrial applications. The Parker Powerlift 477 medium-pressure hose has been specifically developed for the crane and lifting-equipment market. The Powerlift features two steel-wire braids and offers a combination of higher working pressure, smaller outside diameter based on compact hose construction, tight bending radius and light weight.

The nitrile inner tube offers increased chemical resistance to bio oil and the outer cover is resistant to abrasion, providing longer service life and reduced overall equipment costs. The Remoflex 412 is a highly flexible pilot-line hose for an increased constant working pressure of 12.0MPa and meets the requirements of modern hydraulic control systems, mainly used in mobile applications. The hose combines an abrasion- and ozone-resistant cover with a small outside diameter and fluid compatibility through a nitrile inner tube.

The Remoflex 412 is aimed at industrial sectors, especially space-restricted mobile construction equipment. The Push-Lok Plus 801 is a low-pressure hose with a higher working pressure and extended colour range. The hose features Parker's Push-Lok self-grip system, which makes assembly easy and fast with no need for tools or clamps. The hose is available in seven colours to simplify identification, production processes, control of maintenance intervals and stock planning. Push-Lok fittings are available worldwide and are made to DIN, BSP, SAE, JIC and ORFS in steel, brass and stainless steel.

Parker Presents Midigas Nitrogen Generator

The Industrial Division of Parker Hannifin will exhibit its latest nitrogen-gas generator for the food sector at the Gulfood exhibition in Dubai, from 21-24 February 2010. Industrial nitrogen-gas generators are an alternative to traditional bottled or bulk storage nitrogen sources in applications such as modified atmosphere packaging, purging, blanketing and pressure transfer.

A fully operational Midigas nitrogen generator will be on display at the show and Parker will demonstrate how food-grade nitrogen can be produced from a standard compressed-air supply, safely and cost effectively. The Midigas range, in addition to the Maxigas nitrogen-gas generation models, have been developed as compact, stand-alone units that allow food processing and packaging companies to produce their own supply of nitrogen in-situ and on demand. The generators are said to be capable of producing an immediate supply of high-purity nitrogen safely and reliably.

The Midigas and Maxigas generators require power and compressed-air connections to install. They are modular in design so that each system can be extended as and when nitrogen requirements increase. The systems use pressure swing adsorption technology, with pairs of extruded aluminium modular columns filled with high-performance carbon molecular sieves to adsorb oxygen from a compressed-air supply. The larger nitrogen molecules pass through each sieve to a storage vessel, from where the nitrogen can be supplied at carefully controlled pressures as a carrier, make-up or purge gas.

The generators are part of a wide range of separation and filtration systems available from the Industrial Division of Parker Hannifin. They are backed by a worldwide network of manufacturing, sales and technical support centres.

Parker Replaces RSD Steel Parts With Peek Polymer

Parker Hannifin, based in Mainz-Kastel, Germany, has replaced the steel components of its RSD quick couplings with the Victrex Peek polymer. The company wanted to replace the components with one single injection-moulded part that reduced the number of components to be assembled and that controlled the overall production costs. The RSD couplings are used to connect and disconnect the hydraulic lines between a tractor and its various items of equipment (a trailer or a plough, for example) without using any tools.

The technology of the RSD coupling allows for the completely safe connection of a male connector, whether pressurised or not, under adverse conditions, such as under a maximum pressure of 250bar (3,626psi), and withstands a return flow rate that may reach 190 litres per minute (50.2 gallons per minute) and even beyond for a few seconds at a temperature close to 120C (248F). David Aragones, project manager at Parker Hannifin, said: 'Apart from the high performance demanded of the coupling, it was essential for us to control our production costs by reducing the number of metal components.

'Consequently, we sought a multipurpose material that was both highly flexible and capable of withstanding high loads over a wide range of temperatures in order to allow us to incorporate as many functions as possible in the clip,' he added. The Victrex Peek polymer valve minimises the number of components in motion during connection and disconnection. The shape of the clip and the elasticity and the fatigue resistance of the material ensure the reliable and durable connection of the pressurised male connector.

Aragones continued: 'The use of this high-performance plastic has allowed us to offer an entirely innovative, patented design. 'These connectors are particularly valued for their pressure-resistant characteristics and their compactness,' he said. Didier Padey, market development manager at Victrex Europe, said: 'Victrex Peek polymer retains its mechanical properties even in aggressive environments at high temperatures.

'Apart from its outstanding thermal performance, it also presents a unique combination of properties; in this case, it is the mechanical resistance and ductility, even under the most adverse conditions, that led to the specification of the Victrex Peek polymer for the valve clip of the RSD hydraulic couplings from Parker,' he added. Parker has achieved increased design freedom and simplified implementation by injection moulding, while improving the functions of its RSD coupling.

Parker Displays Analytical Gas Generation Systems

Parker Hannifin is currently showcasing its latest analytical gas generation systems at the Arablab exhibition in Dubai, which runs until 12 January 2010. The products being shown include high-performance hydrogen, nitrogen and dry-air generators, which have been developed to improve the productivity and profitability of laboratories working in areas such as life sciences, chemical analysis and spectroscopy.

In particular, Parker is exhibiting its latest range of high-purity analytical nitrogen generation systems, which incorporate the latest pressure swing adsorption and membrane fibre technology and which reduce the cost of gas in the laboratory. The compact, self-contained generators, each with a small footprint, are fully automatic, simple and safe to set up and use; they incorporate reliable, low-maintenance technology, giving a long, trouble-free operating life, according to the company.

Systems provide an optimum range of flow rates and purities suitable for LC/MS applications, especially Applied Biosystems and Agilent Technologies instruments. The Parker nitrogen generators that employ pressure swing adsorption (PSA) technology utilise extruded-aluminium modular columns that are filled with a high-performance carbon molecular sieve to adsorb oxygen and moisture from a compressed-air supply.

The larger nitrogen molecules pass through each sieve to a buffer vessel, where the nitrogen can be supplied at carefully controlled pressures. The surface area of the carbon molecular sieve material and the resultant contact time of the compressed air with the carbon molecular sieve give rise to flow rate and purity. The Parker nitrogen generators that employ novel hollow-fibre membrane technology separate air into nitrogen- and oxygen-enriched streams via nano-porous polymeric material.

The pre-filtered clean dry air is separated, yielding high-purity nitrogen suitable for a variety of applications within the life-science, chemical-analysis and spectroscopy market sectors. Similarly, the latest hydrogen gas generators from Parker have been developed to produce a safe, controlled and precise flow of ultra-high-purity hydrogen for chromatography, chemical-adsorption, organic-synthesis and atomic-spectroscopy applications. Parker hydrogen generators utilise separation techniques based on proton exchange via specially developed proton exchange membranes.

Such technology provides an efficient method of separating hydrogen from water, offering levels of purity up to more than 99.9999 per cent, with flow rates between 100ml/min and 1,100ml/min. Parker hydrogen generators offer a safe, cost-effective and reliable alternative to high-pressure hydrogen, helium and nitrogen cylinders that are commonly used in today's laboratory workflows, particularly for gas-chromatography-fuel and carrier-gas applications. Parker is also introducing the zero-air generator range that utilises core platinum catalyst technology to produce clean-dry hydrocarbon-free air.

An external supply of compressed air is pre-filtered and passed through a heated platinum catalyst module whereupon the air stream is oxidised, removing organic impurities. The resulting hydrocarbon-free air stream lowers the signal-to-noise ratio, ensuring a flat constant baseline with no peaks or fluctuations. Each system is stackable with selected hydrogen generators to form a gas station suitable for all known GC combustion detectors. All Parker gas generation systems are backed by the company's network of manufacturing, technical and customer support centres.

Parker E:Trainer Offers Hydraulic System Knowledge

Parker Hannifin has launched an interactive online learning programme - E:Trainer - designed to help OEMs and end users of hydraulic systems to improve system performance and profitability. The free e-learning facility is said to provide a simple but effective method of helping engineers understand the problems that can be caused by moisture or particle contamination and the latest solutions available for different applications.

The E:Trainer website allows all those involved in the specification, design, operation and maintenance of hydraulic systems to access interactive modules that make learning easy and convenient. Modules cover hydraulic fluid basics, the sources of particle contamination, water contamination and the ways in which contamination can cause damage to different system components.

Once users have completed the online e-learning modules they are able to register free-of-charge for Parker's residential courses that are run throughout Europe and explore different aspects of filtration technology in considerable detail. Users can then use this knowledge to assess their own systems, to identify possible areas of weakness, and then improve the cleanliness and reliability of equipment by installing effective filtration solutions.

Parker Pneumatic Cylinder Senses Strokes

Parker Hannifin has launched a clean-line pneumatic cylinder featuring a multi-position, programmable stroke-sensing system. Designated the P1D Clean, the cylinder incorporates an internal foil-positioning sensor that eliminates external dirt traps and makes the P1D suitable for applications in the food sector.The potential for remote programming, combined with multi-position sensing of the cylinder rod position, allows food processing and packaging machine builders and end users to improve machine performance.

The P1D cylinder has a smooth design that conforms to the criteria established by the European Hygienic Engineering and Design Group and to EN 1672-2:2005. This enables the P1D to be used in areas where equipment has to be suitable for intensive cleaning and resistant to a range of potentially aggressive substances. This has been achieved by the development of sensor technology that allows the sensor system to be integrated into the internal profile of the cylinder. This technology is based on a thin, robust, multi-layer strip running along the length of the cylinder.

The strip comprises a flexible, conductive magnetic foil positioned above, and separate from, a potentiometer formed from two longitudinal circuits. A permanent magnet mounted around the circumference of the piston is then used to draw the conductive layer into contact with the potentiometer so that the exact position the piston can be established as it moves. The sensor strip is fed directly to a logic and software PCB, again positioned within the cylinder profile, with a single stainless-steel M12 connector and food-industry-approved TPE seal providing a link to external control devices.

These include an optional hand-held programming unit or a conventional PLC, enabling the system to set up and be reconfigured remotely without the need to access machine components. The facility to establish up to four position signals can be set anywhere along the stroke length and changed as required; there is also scope to increase this number in future. These presets can be used to determine factors such as piston position or for enhanced control of machine sequences, deceleration of pre-start, or other machine movements. Parker will also supply cylinders preconfigured to further reduce installation times.

The P1D cylinder is fully sealed, has been tested and approved to IP67 and, where applicable, meets IP69K specification. It is also constructed to ISO 15552 dimensional standards, enabling it to be changed for existing devices. Parker has refined the external surface extrusion and end caps to ensure that the P1D is self draining and that the ingress of contamination is prevented, even when subjected to regular washdown. The P1D is available in bore sizes from 32 to 125mm with a stroke length of up to 500mm and can be supplied without the sensor system.

Parker Gearhead Offers Optional Output Faces

Parker's Electromechanical Automation Division has announced an expansion to its line of PV gearheads. The PV115 offers a wide assortment of output face options along with high radial load and output torque performance. The output face options have the same output face dimensions as Parker Bayside's PX series, Alpha's LP series, Neugart's PLE series, Stober's PE series, as well as standard NEMA output face dimensions.

The PV115 also supports larger belt actuators, including Parker's HPLA120 and HLE150. The PV gearhead's design achieves high radial loads by using precision taper roller bearings.

With high input speeds and efficiency up to 97 per cent, PV gearheads are suitable for industrial requirements, including belt and pulley, conveyor and production machinery; automotive production and inspection equipment; medical and life science applications, including lab instrumentation, device manufacturing and pharmaceutical requirements; packaging; and many other commercial applications. The PV115 is covered by a three-year warranty.

Parker Introduces HL Profile Rod Seals

Parker-Pradifa has unveiled the HL profile series of rod seals. Their pressure-activated, cascading dynamic sealing lips, in combination with P6030, a sealing material, reduce static and dynamic friction. Compared with conventional U-rings, the Ultrathan HL rod seal can reduce friction-related losses by 30 to 70 per cent, depending on load.

The resulting higher efficiency of hydraulic systems leads to significant energy savings. Friction-optimised seals for hydraulic cylinders also cut costs related to downtime and maintenance. The HL profile causes the sealing edges of the dynamic sealing lips to successively contact the mating surface as system pressure rises. This significantly reduces friction in the pressureless state and in low-pressure conditions. The sealing effect increases with the number of sealing edges.

At the same time, dynamic friction slightly increases as the contact area enlarges. Overall, however, it remains at a very low level. Since only the primary sealing edge is engaged in pressureless conditions, the functional principle minimises the high breakaway friction typically occurring after prolonged downtime. The small contact area reduces the generation of heat and friction, allowing higher travel speeds.

Depending on the system pressure applied, the individual sealing lips of the rod seal are activated by the deformation of the seal's cross-section. This reduces the amount of oil seepage that occurs during the cylinder stroke, and thus increases the sealing effect. In case of slow travel speeds, the risk of stick-slip is nearly excluded. The P6030 material has been specifically designed for low-friction fluid power applications.

In addition to good media resistance, it exhibits increased temperature and wear resistance as well as low compression set. It is resistant to mineral oil-based hydraulic oils and PAO fluids. Materials for bio-fluids (HEES and HETG) are available as well. The HL rod seal can be used as a single seal with a wiper and as a secondary seal in a sealing system behind a primary or buffer seal.

The seals have been designed for a maximum operating pressure of 250bar, at operating temperatures between -35 and +110C. The HL Ultrathan rod seal is suitable for a wide range of hydraulic applications requiring minimal friction, such as lifting platforms, loading gates, forklift trucks and lift trucks. Test cylinders, automation cylinders, cylinders for agricultural equipment and gas springs are other typical fields of application.

Parker Hannifin Generator Produces Pure Nitrogen

The Process Filtration Division of Parker Hannifin has launched the Nitroflow Lab: a self-contained generator that produces up to 32lpm of pure LC/MS-grade nitrogen at pressures up to 8bar. A combination of compressor, filtration and membrane separation technologies produces a continuous on-demand supply of pure nitrogen, maximising laboratory productivity.

High- and low-pressure compressors are carefully matched to hollow fibre membranes to separate the clean air into a concentrated nitrogen stream. The dual-compressor generator ensures that the Nitroflow Lab has several technical advantages over all other existing LC/MS nitrogen generators. Nitrogen is produced at low pressure and is then compressed to 8bar. This is intended to ensure minimal maintenance of the system with no compressed air filter replacements or condensate.

The compressor life is guaranteed under the Parker warranty for 8,000 continuous running hours. Typical applications include LC/MS nebuliser gases for APCI and ESI, ELSD, Turbo Vaps and chemical solvent evaporation. The Nitroflow Lab has been tried and tested by all the major LC/MS manufacturers. Parker Hannifin is a provider of motion and control technologies.

Parker Introduces Parfit Hydraulic Filter Elements

The Filtration Division of Parker Hannifin has introduced a range of hydraulic filter elements designed to eliminate the problems of equipment downtime and failure caused by fluid contamination. The Parfit elements are interchangeable with products from all other suppliers, giving end users the option of sourcing all filter elements from a single manufacturer.

This approach can reduce stock levels and, as the Parfit elements are manufactured to high standards, can extend operating life. Suitable for use in a wide range of applications including industrial and mobile plant, test rigs, aircraft ground support equipment, steel and paper mills, the Parfit elements have been developed to allow both system designers and end users to meet current and future environmental regulations.

In particular, the Parfit filter system uses a standard metal housing and replaceable element, which can be changed during routine maintenance, leaving the housing in place, and reducing both waste disposal and element replacement costs.

In addition, Parfit filter elements can be used as a direct replacement for competing products and are manufactured to stringent quality standards.

Every unit is produced to extremely tight tolerances with features including corrosion resistant end caps and fully bonded construction for maximum strength. The new Parfit elements conform to international ISO standards, governing collapse and burst resistance, fabrication integrity, material compatibility and flow fatigue characteristics, as well as to the internationally recognised multipass test.
