This product category includes a variety of flanges and sealing elements designed specifically for Schwing concrete pumps. These components are vital for maintaining leak-free, high-pressure connections across hydraulic, water, and material delivery systems. Flanges provide robust mechanical connections, while sealings (such as O-rings and wear rings) ensure fluid containment and system integrity under extreme operating conditions.
Key Features:
Flanges
Heavy-Duty Construction Engineered from high-grade steel or alloy materials to handle pressure fluctuations, vibration, and mechanical stress typical in concrete pump operations.
Precision Machined Manufactured to tight tolerances to guarantee alignment and leak-free joints.
System-Specific Designs Available in threaded, welded, or clamped styles depending on the type of line (hydraulic, water, or concrete).
Direct Fitment Designed to meet Schwing’s specifications for easy integration into existing equipment.
Sealings
Premium Elastomeric Materials Made from NBR, Viton®, PTFE, polyurethane, and other advanced materials for chemical compatibility and wear resistance.
Leak Prevention Technology Built to maintain system pressure and prevent contamination by blocking fluid and slurry leaks in both static and dynamic applications.
Application-Specific Types Includes standard O-rings, guide rings, lip seals, shaft seals, and wear rings for hydraulic cylinders and pump systems.
Common Types in Schwing Equipment:
Component Type
Description / Use Case
O-Rings
Standard round seals for static and dynamic connections in hydraulic and water systems.
Wear Rings / Guide Rings
Polymer-based rings guiding pistons and rods in cylinders to prevent metal-on-metal contact.
Threaded Flanges
Connect hydraulic lines and fittings in serviceable locations.
Welded Flanges
Permanent, pressure-tight pipe and pump line joints.
Clamp Flanges
Quick-connection flanges for systems requiring frequent disassembly or cleaning.
Retaining Rings
Hold seals or bearings in place inside housings or cylinders.
Typical Applications in a Schwing Concrete Pump:
Hydraulic Systems: Flange connections and sealing points on pumps, valves, cylinders, and control blocks.
Water Systems: Water cleaning and cooling line connections with sealing elements to prevent pressure loss.
Material Delivery Lines: Selected flanges used at the connection points in delivery systems (e.g., clamps or wear sleeves).
Boom and Cylinder Assemblies: Wear rings and seals prevent leakage and maintain piston rod guidance within hydraulic cylinders.
Identification & Ordering Tips:
To ensure correct selection:
Confirm the pump model and serial number.
Consult the Schwing parts manual or OEM supplier.
Reference the part number on the existing component.
Specify system location (hydraulic, water, or concrete delivery line).
Provide exact dimensions (ID/OD/thickness) if markings are missing.
