1 Freudenberg Group Sealing Technology Seals and Sealing Systems for the Pulp & Paper Industry

2 Seals for the Pulp & Paper Industry : Sealing expertise known all over the world Rotary seals is the market leader in the field of seals for the heavy industry. With innovative solutions and pathbreaking products for all branches of activity, we belong to the most renowned specialists in the sector of sealing technology at inter national level. The excellent quality of seals is known all over the world. The high degree of functional reliability, coupled with excellent static and dynamic sealing properties, is acknowledged worldwide by all our clients and throughout all branches of activity in comparative tests at regular intervals. Simmerrings Radiamatic RHS 5 are used for sealing flange bores on large-size gears in the pulp & paper industry. Two functionally adapted elastomer components and an integrated steel strip ensure a high level of functional reliability. The system incorporating the high-speed rotary shaft seal Radiamatic RHS 5 and the water guard 807 will offer you ideally suited sealing effects. Simmerings Radiamatic RHS 5 will continue to provide a safe sealing effect even on shafts offset by up to 3 mm, while ensuring reliable speeds Take advantage of our application engineering expertise, of our rich materials know-how in cooperation with the Freudenberg Research Services and of our fully developed production technology to solve challenging problems on the basis of special solutions. of up to 35 m/s and more. The Radiamatic RHS 5 is self-locking and incorporates a new type of spring system in order to achieve a uniform contact pressure. supplies the whole range of simmerrings, including sensors (seals & sensors).

3 seals in paper manufacture You will receive from high-performance seals for the production process as a whole Hydraulic seals Rotary seals, hydraulic seals, stuffing-box packings and gaskets for mechanical wood pulp manufacture. hydraulic components cover a broad spectrum of applications in the hydraulic sector and are used every time importance is attached to safety and service requirements, as well as to the aspects of costs. Stuffing-box packings and gaskets for wood 3 Our range comprises rod and piston seals, wipers, guides and static seals. Low friction forces, appropriate control options and a high degree of functional reliability will ensure short downtime periods and minimum maintenance operations.

4 3 Stuffing-box packings 3 Gaskets You will find at a comprehensive, clearly-structured standard range of stuffing-box packings developed and produced on the basis of current material research, of state-of-the-art design technology and present-day manufacturing processes. The stuffing-box packing Kombilon is ideally suited for pumps in the paper industry. The special design of Kombilon ensures very low friction forces and a high degree of elasticity. This guarantees, in turn, a long service lifetime and low leakage rates, even in the event of slight radial shaft deflections. The gasket materials Flex-O-Form S and P will provide you with two convincing material versions featuring special properties. Flex-O-Form gaskets consist either of a modified PTFE material (Flex-O-Form S) containing a small percentage of a mineral filler, or of a modified dark-gray PTFE material (Flex-O-Form P) with a small percentage of special graphite acting as a filler. They are used in critical situations involving flange joints and pipe connections. The Flex-O-Form adapts itself to the surface in connection with harder uneven flange materials, too. Environmental protection, minimized burdens on the workplace and great operating reliability are of paramount importance for our stuffing-box packings, too.

5 seals: Your competitive edge Their great extrusion resistance and their superior material quality also make it possible for seals to withstand easily high speeds and a broad range of temperatures. As a result, your machinery will not only make production more rapid, but also much more efficient. The above-average sealing effect prevents any leakage in a reliable way and the machinery failures they entail, but makes it possible for you to save costly downtime periods, while reducing significantly service as well as repair operations. belongs to Freudenberg Fluidtechnic GmbH in Hamburg. Some 900 employees develop, produce and distribute seals and sealing systems for industrial applications. Freudenberg Fluidtechnic GmbH is a company of Freudenberg Seals and Vibration Control of the globally operating Freudenberg Group and is, therefore, tied to the largest global partner and distribution networks for sealing technology. Energy costs will also be drastically reduced with special seals like our Energy Saving Simmerring (Simmerring ESS).
