Product Introduction

Applicable fields: construction engineering, concrete construction

Core applications: cleaning, unclogging, and slurry removal in pump truck pipelines; rapidly eliminating residual concrete to prevent pipe blockages.

Product Feature Overview

Made from high‑strength, wear‑resistant rubber with high density and excellent elasticity, it can withstand the impact forces generated during high‑pressure concrete pumping. To address the tendency of residual concrete to harden and adhere strongly, the sponge balls undergo a special surface treatment that delivers superior abrasion resistance. Driven by high‑pressure water jets, they move rapidly through the pipeline, striking and dislodging hardened concrete deposits from the pipe walls, thereby quickly clearing blockages, reducing the time and cost associated with pipe dismantling and cleaning, and enhancing construction efficiency. Moreover, the product’s exceptional toughness makes it highly resistant to breakage, enabling repeated use and lowering material costs on site.
