Schwing Spare Parts WEARING INSERT DN 180 (SP750) 10129807

This wearing insert DN 180 is a direct replacement part for Schwing concrete pumps, specifically for the swing valve housing assembly. It carries part number SP750 and the original OEM reference 10129807, so you can match it straight to your parts list without guesswork.

Made from a tough, heat-treated alloy, this insert is designed to take the daily abrasion from concrete and aggregate flow. It’s not a soft liner—expect it to hold up against sand, gravel, and high-pressure pumping cycles without deforming or cracking early.

The DN 180 size aligns with standard pipeline bores in larger Schwing pump models. You’ll usually be replacing this during swing valve servicing or when you notice uneven wear patterns or material bypass around the sealing area.

Installation is straightforward: clean the housing seat thoroughly before fitting, then check the mating surface with the adjacent wear ring. No extra machining needed if the original housing isn’t damaged. Always torque to factory specs once seated.

Keep a spare on hand if you’re running high-volume pours or recycling yard work. This insert is a regular wear item—ignoring it leads to housing damage and unplanned downtime. Stick with SP750 to keep your output consistent and your repair hours low.
