About the STAUFF Group
For more than 50 years, the companies of STAUFF Group, since April 2015 also including VOSWINKEL, have been developing, manufacturing and distributing pipework equipment and hydraulic components for mechanical and plant engineering and for service and industrial maintenance.
The overall range currently includes about 40000 standard components in ten product groups as well as a large number of special and system solutions, which are manufactured to customer specifications or based on in-house developments.
Wholly owned manufacturing, sales and service facilities in 18 countries and a tight global network of authorised distribution partners ensure high presence and service paired with a maximum of availability.
With around 1350 employees worldwide, including 550 at five sites in Germany, the companies of STAUFF Group achieved external sales of over EUR 210 million in the business year 2016.

  • Checking bladder and diaphragm accumulators with non-contact RFID technology

    New connection adaptors enable the use of innovative sensors to check hydro-pneumatic accumulators without any loss of pressure

    The new SBAA and SDAA types of accumulator adaptors, which the Werdohl-based fluid specialist Stauff launched for the first time at the Hanover Fair, enable the non-contact checking of the accumulator pressure of hydro-pneumatic bladder and diaphragm accumulators in conjunction with the innovative PT-RF pressure transmitters and a corresponding reader – quickly, easily and without any loss of pressure.


  • 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.

  • 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.

  • 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.
