Product Introduction

The cutting ring is a core wear-resistant sealing part of the S-valve assembly in concrete pump trucks. It works together with the wear plate and undergoes continuous high-speed friction during pumping and switching cycles. Its wear resistance and sealing performance directly affect pumping efficiency, concrete output and equipment downtime. Compatible with mainstream brands such as SANY, Zoomlion and XCMG. Main specifications include:

• Tungsten carbide overlay cutting rings
• Ductile iron cutting rings
• Polyurethane composite cutting rings
• Universal cutting rings for various pipe diameters and models

Product Advantages

• High wear resistance: made of alloy overlay and quality materials, withstands high-speed friction and greatly extends service life
• Excellent sealing: precisely matched with the wear plate to effectively reduce slurry leakage and keep pumping pressure stable
• Impact resistant: high hardness with good toughness, suitable for high-pressure, heavy-load pumping conditions
• Precise dimensions: machined strictly to drawings for a perfect fit and smooth switching
• Complete size range: fits multiple brands and models, easy to replace and reduces downtime
