Tubes and wear parts are essential to the long-term reliability and performance of Sermac concrete pumps. These components are engineered to withstand high pressures, friction, and the abrasive nature of pumped concrete. Tubes are used in hydraulic, water, and support systems, while wear parts protect key mechanical elements and are regularly replaced to maintain optimal function.
Key Features:
High-Durability Materials:
Tubes: Steel or alloy construction for strength and corrosion resistance.
Wear Parts: Bronze, hardened steel, composite polymers, or ceramics for superior abrasion resistance.
Engineered for Performance: Precision-machined for exact fit, ensuring leak-free operation and easy integration into Sermac systems.
Application-Specific Design: Custom-fit for key zones like the hopper, rock valve, slewing ring, and hydraulic circuit.
Replaceable & Service-Friendly: Wear parts are easily accessible and replaceable, reducing machine downtime and maintenance costs.
Typical Applications in Sermac Concrete Pumps:
Tubes:
Hydraulic line conduits
Water delivery pipes
Protective sleeves for moving parts
Structural tube supports
Wear Parts:
Wear Plates & Liners: Found in high-friction areas like hoppers and S-valves
Bronze Bushings: Used in pivot points, slewing rings, and hydraulic assemblies
Wear Rings & Backup Rings: For sealing hydraulic or pumping components
Valve Components: Parts for water and hydraulic valves, including control levers
Visual Identification (Based on Image):
Bronze-Colored Multi-Grooved Cylinder: A bronze bushing, commonly used in high-friction joints or pivots, known for its excellent wear resistance and self-lubricating properties.
Metallic Rings with Bolt Holes: Likely mounting flanges, hose connectors, or wear plate retainers.
Black O-Rings & Seals: Standard hydraulic or water seals, used across multiple systems to prevent fluid leakage.
Curved Metallic Segments: These may be wear liners or plates for curved concrete flow paths (e.g., elbows or S-valve areas).
Green Component with Lever: Likely a manual control valve or flow diverter, possibly part of the water pump or flushing system.
Silver Rings with Internal Grooves: Could be bearing sleeves, inner races, or seal carriers.
Kidney-Shaped Metal Plates: Classic design for rock valve wear plates, subject to heavy impact and abrasion.
Prominent Component – Bronze Bushing:
Use Cases:
Boom pivot points
Hydraulic cylinder guide points
Hopper mixer bearings
Slewing mechanisms
Advantages:
Excellent wear performance
Self-lubrication reduces maintenance
Fits into steel housings for high-load areas
Identification & Ordering Guidelines:
For accurate replacement and fit:
Provide the Sermac model and serial number
Check for engraved part numbers or codes
Note the installation location (e.g., boom pivot, rock valve plate)
Supply precise measurements: ID, OD, thickness, flange dimensions, etc.
If possible, include photos or diagrams for reference
