Schwing Spare Parts WEARING INSERT DN 150 (SP500) 10129809

This is a genuine Schwing wear insert, part number **10129809**, sized **DN150** and engineered specifically for the **SP500** concrete pump model. It fits directly into the rock valve assembly of Schwing stationary pumps, including BPA 450/500, SP750 and WP1000 series, serving as a core wear component in the hopper system.

Built with a high-strength steel body fused with **tungsten carbide** inserts (HRA >86) for maximum abrasion resistance. The surface is treated with German-sourced Vautid-150 hardfacing electrode (HRC >63), delivering exceptional durability against harsh concrete mixes and long pumping hours.

Designed to seal and protect the rock valve from concrete flow erosion, this insert maintains precise clearance between valve components. It minimizes leakage, reduces friction and ensures consistent pumping efficiency even with high-viscosity or aggregate-rich concrete, critical for heavy-duty job sites.

Offers a service life of **30,000–80,000 cubic meters** (based on C30 concrete), outlasting standard wear plates in demanding conditions. Regular inspection (every 5,000–10,000 m³) is recommended; replace when carbide edges show excessive wear to avoid valve damage and downtime.

Genuine Schwing OEM part, fully interchangeable with original components and manufactured to strict factory tolerances. Each unit is inspected for dimensional accuracy and material integrity, ensuring perfect fit and reliable performance in SP500 and compatible models.
