  • New to the range: Multi-mantle filter elements for marine and process technology applications

    Stauff completes its range of filter elements from in-house production “made in Germany”

    Stauff has further expanded its range of replacement filter elements for single, double and automatic filters “made in Germany”: Multi-mantle filter elements from the SBM range, which are now also part of the filter manufacturer's stock range, consist of up to three cylindrical filter cartridges with different diameters placed inside each other, creating the largest possible filter surface on a small footprint.

    Stainless steel mesh with variable micron ratings between 10 and 2000 micrometres is used as a standard filter material. Like the mesh, the inner support tubes for the elements are also made of stainless steel and their end caps of aluminium. This means that mantle filters from Stauff can easily be cleaned in an ultrasonic bath or manually as required.

    Multi-mantle filter elements are generally used in marine applications for filtering fuels and lubricants as well as water. The elements are also used in the processing industry for purifying water, oils, coolants and chemicals.

    Stauff customers benefit from full access to several thousand different replacement filter elements for applications with hydraulic oils, lubricant oils, fuels, water, chemicals and coolants.

    In addition to the high availability from stock in the automated logistics centre in Neuenrade, which allows very short processing times and ensures maximum process reliability, delivery quality and timely deliveries, the company also has the benefit of technical expertise resulting from decades of experience as a manufacturer of filter elements. The heart of research and development is the Technology Centre at the Stauff headquarters in Werdohl. This is where a team of experienced engineers works on the development of new products and solutions, from ideas to market launch. Beyond this, the task and the objective are to revise the existing products and solutions with regard to the increasing requirements of the market, striving for consistent optimisation.

  • Mobile filter units SMFS-U for nominal flow rates of up to 60 and 110 litres per minute

    Support for preventive maintenance
    Cleaning mineral oil with mobile bypass filters

    Stauff has further optimised and expanded its range of mobile filter systems with regard to design and performance. The design of the two versions of type SMFS-U for nominal flow rates of up to 60 and 110 litres per minute respectively was updated and the version SMFS-U-CM with an integrated 8-channel particle monitor including an oil moisture and temperature sensor was added. The connection between the particle counter and the machine control on this version allows an ISO purity class to be defined at the operating panel. The device then automatically shuts down after this level has been reached.

    With the variants now available from stock, the mobile units cover a wide range of applications: In temporary operation, they not only support the preventive maintenance of small and medium-sized hydraulic oil and lubricant oil systems, they also allow these to be filled with fresh oil and cleaned. On large volume systems, permanent operation as a bypass filter is also possible without problems.

    Replacement filter elements of the NR-630 range from Stauff – manufactured in-house in Germany just like the actual filter units – ensure that the systems are properly operated and that the desired or required purity classes are achieved for the oil. The filter housings are equipped with convenient fold-and-twist bolts, allowing the filter elements to be replaced quickly and without any special tools.

    High-quality components – optimum protection

    Three-phase motors (3x400VAC/50Hz) with an output of 2.2 and 4 kilowatts respectively are installed to drive the gear pumps of the mobile filter units. In addition to the output being adapted to the requirements of modern service and industrial maintenance tasks, their most important feature is the high energy efficiency (class IE2).

    To prevent damage to the components in the best possible way, pressure switches deactivate the motors before excess pressure occurs between pump and filter housing. Possible causes for excess pressure are bent or clogged lines, overly viscous media as well as extremely contaminated filter elements which are not replaced despite triggering of the differential pressure indicators which are integrated in all devices.

    To ideally protect the pump against the negative effects of coarse contamination, a washable stainless steel mesh pre-filter with a micron rating of 200 micrometres is additionally used already in the suction line.

Product news

  • Filterelements with flow protection

    Plastic sheath prevents damage and mix-up with other brands. The STAUFF flow protection is a perforated plastic sheet that completely encases the pleats of the fi lter from the outside. The flow protection for filter elements protects the folding of the
    filter elements against damage caused by large dirt particles in the flow as well as during handling. A further positive effect is that the volume flow is distributed more evenly by the protective sheath, thus ensuring an efficient flow rate.The flow protection is also available in neutral or with a customised imprint.

  • Protecting filter elements against direct flow impact

    Plastic sheath prevents damage

    The sensitive filter bellows on filter elements are frequently prone to damage during transportation, storage and filter replacement work. In addition, large particles in the flow of fluid may harm the filter material. At the MAINTENANCE 2012 trade fair, Stauff will be presenting their solution: SE series filter elements with protective sheath. This is a thin, perforated plastic sheet that completely encases the pleats of the filter from the outside as well as making the element more stable. A further positive effect is that the volume flow is distributed more evenly by the protective sheath, thus ensuring an efficient flow rate. In its standard version, the foil is printed with the Stauff logo, eliminating any mix-up with other brands. Larger quantities can also be produced with a customised imprint on the sheath.

  • Clean oil OLSW water-absorbing off-line filter

    Water particles from existing humidity are deposited in hydraulic oil. Together with other contaminants, this causes the degradation of important additives in oil, the effectiveness of the lubrication is reduced, and oxidation is accelerated. The Stauff OLSW off-line filter can remove these, both water and other contaminants from the hydraulic fluid. An upstream spin-on filter element filters the water and coarse particles, and in the OLS system, the remaining water and ultrafine particles up to 0.5 microns are removed. The OLSW is equipped with a motor pump unit, which pumps fluid out of the system, filters it, and returns it to the tank. This means that the OLSW can run separately, even when the hydraulic system is switched off, and continuously filter the oil. After just a few weeks, a reliable improvement in the oil purity levels can be achieved. The maintenance intervals for the entire system can be extended, far less repairs are necessary, and repair and replacement part costs are reduced. Existing systems can easily be retrofitted.

  • Offline filters enhance oil purity

    Offline filters enhance oil purity

    In principle, the subject matter only measures between one and three microns. That’s how fine the dirt particles are that can cause contamination in the hydraulic systems of injection moulding machines. Stefan Beez, sales engineer at Stauff: “The filters used on the machines are equipped with filter grades of between three and ten microns. This means that particle sizes of less than three microns can only be caught to a certain extent. But it is especially the concentration of ultra-fine particles that causes intense wear on the hydraulic components.” Because conventional filters that function in the main stream only remove particles up to three microns, a so-called offline filter with an integrated motor pump unit has been developed by Stauff. Using this offline filter system (OLS), practical tests carried out with a renowned operator of injection moulding machines showed significant improvements in the purity class according to ISO 4406, namely from 15/13/10 (pressure filtration three microns) to 14/11/8.
    This result speaks in favour of Stauff’s strategy to back slow but highly effective filtration in the so-called bypass flow. With this technology, the fluid is drawn off the hydraulic system and passes through an ultrafine, purpose-developed cellulose medium that removes even the tiniest particles of less than one micron. The compact offline filter is easily installed in the hydraulic system of the machine and works independent of the plant cycle, even when the injection moulding machine is at a standstill. “The filter prolongs the service life of the oil and of the costly, sophisticated components,” explains Stefan Beez. “With the OLS, the purity of the oil is improved after only a few weeks and, due in particular to the increased availability of the installation, pays itself off within about six months.” Find out further details on the Stauff easyfair stand No. C 01 at the MAINTENANCE 2011 trade fair taking place at Landschaftspark Duisburg North (Power Station) on 23 and 24 February.
