A concrete pump wear plate is a vital component within the pumping mechanism, designed to resist the abrasion caused by the pumped concrete. It's a protective shield that helps extend the pump's lifespan by minimizing wear and tear. These plates are typically located in the S-transfer tube or between the S-valve tube and the cutting ring, where they encounter high friction with the moving parts and the concrete itself.
