Zoomlion Spare parts CUTTING RING DN 260

The Zoomlion Spare Parts Cutting Ring DN 260 is a high-performance OEM component for concrete pump delivery systems, engineered to control concrete flow and seal the connection between the pump’s S valve and delivery cylinder, ensuring stable material transfer in high-pressure pumping scenarios.

Forged from wear-resistant alloy steel with a hardened surface treatment, the DN 260 cutting ring withstands extreme abrasion from concrete aggregates and chemical erosion from admixtures, extending its service life by 50% compared to standard carbon steel alternatives in heavy construction use.

Precision-machined to match Zoomlion’s DN 260 pump system specifications, the ring features a seamless fit with compatible S valves and wear plates, eliminating gaps that cause material leakage or pressure loss, and ensuring consistent pumping efficiency for large-scale projects.

Its optimized geometric design reduces flow resistance and minimizes concrete buildup, preventing blockages that lead to costly downtime. The ring supports continuous pumping pressures up to 45 MPa, making it ideal for high-demand infrastructure and commercial construction tasks.

As a genuine Zoomlion spare part, the Cutting Ring DN 260 comes with factory quality certification and a warranty, providing fleet managers and contractors with a reliable replacement option to maintain pump performance and avoid unplanned construction delays.
