Scraper ring for Putzmeister machinery

The scraper ring, part number 238585009, functions as a protective barrier for hydraulic cylinders within Putzmeister equipment. As the piston rod retracts into the cylinder housing, this component clears the rod surface of contaminants such as dirt, dust, and moisture. By preventing these particles from entering the cylinder, the scraper ring helps maintain the integrity of the internal seal assembly and the hydraulic fluid. This component is compatible with a range of Putzmeister concrete pumps and distribution booms that utilize hydraulic cylinders for movement and stabilization.

Proper operation of the hydraulic system relies on the scraper ring to maintain a clean rod surface during the full stroke of the cylinder. When the rod is extended and exposed to the environment, it can collect debris that would otherwise be drawn into the gland area. The scraper ring features a specialized lip designed to maintain contact with the rod, ensuring that foreign matter is wiped away before it can reach the primary seals or the cylinder bore. Maintaining this component is a standard practice for protecting hydraulic actuators from premature wear and contamination.
