Ensure long-lasting performance and system integrity with the Putzmeister® Rings & Plates Series, a collection of essential wear and sealing components designed to protect and support the core operating systems of your concrete pump. Engineered for durability, precision, and compatibility, these parts play a critical role in maintaining hydraulic efficiency, structural alignment, and component longevity under demanding jobsite conditions.
🔧 Key Features & Benefits
Advanced Wear Protection Precision wear rings and plates safeguard vital components—such as pistons, cylinder walls, and S-valve housings—from abrasion caused by concrete and moving parts.
Leak-Free Sealing Includes O-rings, sealing rings, gaskets, and backup rings to ensure fluid-tight connections in both hydraulic and concrete delivery systems.
Structural Support & Alignment Mounting and support plates maintain proper positioning and secure attachment of major assemblies including hoppers, cylinders, and valve mechanisms.
OEM Fit & Function All components are manufactured to exact Putzmeister® specifications for direct replacement and seamless performance in existing pump systems.
Durable Materials Constructed from wear-resistant metals and high-performance polymers that withstand the high pressure, abrasion, and mechanical stress of concrete pumping.
🧩 Component Overview
Wear Rings Designed to guide the pistons within the main pumping cylinders while protecting the cylinder walls from friction and wear. Often include lubrication grooves for smooth operation.
Figure-Eight Wear Plates Typically installed in the S-valve area. These plates protect the valve housing where concrete flow diverges, making them highly resistant to abrasion.
Yellow Mounting/Support Plates Heavy-duty structural plates used to secure various components—such as the hopper or valve assemblies—to the pump frame.
Metallic Seal Retainer Rings Support elastomeric seals in high-pressure applications and prevent seal extrusion or displacement during operation.
O-Rings & Sealing Rings Provide sealing in both static and dynamic applications. Common in hydraulic cylinders, pump housings, and line connections.
Gaskets Flat sealing components placed between flanges or surfaces to prevent hydraulic oil or slurry leakage under compression.
🏗️ Function Within the Pump System
Wear Rings: Protect pumping cylinders and pistons from premature wear while guiding movement.
Figure-Eight Wear Plates: Shield the S-valve chamber from the high friction of flowing concrete.
Mounting Plates: Ensure firm, aligned installation of critical subassemblies.
Sealing Rings, O-Rings & Gaskets: Maintain leak-proof hydraulic and delivery systems by sealing critical joints and surfaces.
Backup Rings / Seal Retainers: Reinforce soft seals under high pressure and extend system service life.
✅ Why These Components Matter
Failure of even the smallest wear ring or seal can lead to:
Hydraulic fluid or concrete leakage
Reduced pressure and pumping efficiency
Accelerated wear of expensive parts
Costly downtime and repair needs
Regular inspection and replacement of rings and plates are essential to maintain high system performance and protect your investment.
