Herbert Hänchen, a trusted German manufacturer of one of the largest test actuator ranges on the market, will present its new Servoseal sealing element, a dynamically sealing synthetic ring. The integrated retaining ring made of carbon prevents excessive pressure build-up on the sealing surface due to hydraulic pressure. At small amplitudes, no wear or scoring is produced on the counter-faces due to lack of lubrication, meaning it can be used in the sleek servo actuator series 120 and 300 just as well as in the testing actuator series 320.
This gives users a cost-effective and extremely powerful alternative to other actuator brands. These servo actuators enable testing tasks with small amplitudes and frequencies up to 25Hz, low side loads and long strokes, delivering advantages including low friction, low wear and no leakage or functional oil. Hänchen offers a wide range of actuator dimensions in this series.
It is possible to equip the customary hydrostatic testing actuators of the 320 series for highly dynamic movements and high side loads with the Servoseal and thus achieve better hydraulic efficiency. Furthermore, a smaller control valve may often be used, as there is no functional oil flow and no leakage of the gap seal.
