Rubber hoses are essential components in Schwing concrete pump systems, providing flexible connections for concrete delivery, hydraulic actuation, water supply, and air lines. Designed to perform under high pressure and in harsh construction environments, these hoses offer both durability and flexibility where rigid pipes cannot be used.
Key Features
Flexible Construction: Engineered from high-grade rubber compounds, allowing for bending, movement, and vibration absorption without compromising strength.
Reinforced Layers: Built with textile or steel wire reinforcements to handle high internal pressures in hydraulic and concrete applications.
Abrasion-Resistant Linings: Interior surfaces are designed to withstand the abrasive nature of concrete slurry, extending hose service life.
Custom Sizes Available: Offered in a wide range of diameters (e.g., DN50–DN150) and lengths to suit different pump configurations and job site requirements.
Pressure Ratings: Available in various classes, from low-pressure water hoses to high-pressure hydraulic and delivery hoses.
End Fittings: Equipped with securely bonded fittings such as flanges or couplings for quick, leak-free connection to Schwing pump systems.
Common Applications
Concrete End Hose: Final delivery hose on the boom or manual pour section, designed to handle the abrasive flow of concrete.
Hydraulic Hose: Used to convey pressurized fluid to power boom movement, swing arms, and other hydraulic components.
Water Hose: Delivers water for cleaning cycles or cooling in specific systems.
Air Hose: Used in auxiliary pneumatic systems, where applicable.
Suction Hose: May be used in low-pressure intake zones, depending on pump configuration.
Typical Hose Types
Hose Type
Characteristics
Concrete Delivery
Heavy-duty, large diameter (e.g., DN125), reinforced for high-abrasion resistance
Hydraulic
High-pressure rated, typically steel braided with crimped end fittings
Water Supply
Flexible, lower-pressure rubber with standard water hose fittings
Air Hose
Light-duty, abrasion-resistant, used in control circuits or air-powered systems
Custom Hose Kits
Bundled solutions including hoses and matching fittings for specific pump models
Selection Guidelines
To ensure correct fit and safe performance, specify the following when selecting a hose:
Application (e.g., concrete delivery, boom hydraulics, cleaning water line)
Internal Diameter (DN) and length
Required pressure rating (working and burst pressure)
Type of end fittings (e.g., SK148 coupling, flange, threaded fitting)
