Redura® Piston Sealing Systems Redura® Piston & Rider Ring Systems Careful Selection, Combination and Arrangement Make the Difference Double acting pistons – The piston sealing elements are only subject to the dynamic pressure component varying between the suction and discharge pressure. – The static pressure component is omitted due to the identical suction pressure at both ends of the piston. – For challenging applications like double acting compression of hydrogen, sealing rings with improved sealing efficency are recommended; this ensures longer life and sustained efficiency. – Robust piston...
