Product Introduction

Concrete pump truck sealing parts are essential wear and sealing components that ensure the tightness, wear resistance and stability of the pumping system. They are compatible with mainstream brands such as SANY, Zoomlion, XCMG and Putzmeister. Main products include:

• Concrete pistons and sealing assemblies (delivery cylinder pistons)
• Cutting rings and wear plates (key sealing & wear parts of the concrete S-valve)
• Wear rings and guide rings
• O-rings, oil seals and dust seals (hydraulic / pneumatic seals)
• Rotary joint seals and lubrication sealing assemblies

Product Advantages

• Precision fit: tight tolerance control ensures reliable sealing with the delivery cylinder and S-valve
• Wear & pressure resistant: made of quality materials such as polyurethane and wear-resistant rubber, resistant to abrasion, high pressure and impact
• Long service life: optimized structure and formulation extend replacement intervals and reduce downtime
• Wide compatibility: fits multiple brands and models with a complete size range for easy replacement
• Stable delivery: effectively prevents mortar leakage and maintains stable pumping pressure for higher efficiency
