The CW28-F double wiper is an advanced sealing element specifically engineered for high-frequency operations in injection moulding machines, presses, and steel hydraulic mills. This Dynamic double-acting scraper features a profile ring made from high-performance polymers PTFE energized by two O-rings, ensuring excellent regulation and positioning during reciprocating movements. As a premium alternative to the Merkel Double Wiper PT 2, the CW28-F is designed to work in tandem with heavy duty step rod seals, effectively improving total system tightness. Its low-friction, stick-slip-free properties make it especially suitable for large-diameter cylinders where precision and reliability are paramount in demanding industrial environments.
