The Concrete Pump Hose is a core component in a concrete pumping system, directly bearing the highest pressure and wear. It plays a crucial role in safely transporting heavy building materials such as mixed concrete, mortar, and plaster slurry to the pouring point. This hose features a multi-layered composite structure. The inner layer uses a high-strength NR/BR synthetic rubber compound, possessing excellent wear resistance and tensile strength, capable of withstanding the high-speed erosion of coarse aggregates in the concrete. The reinforcing layer uses a four-layer interwoven high-strength steel wire structure, providing stable and reliable pressure bearing capacity, ensuring no bulging or bursting under working pressures up to 85 Bar (approximately 1233 PSI). The outer layer uses NR/SBR synthetic rubber with excellent weather resistance, resisting the corrosion of ultraviolet rays, ozone, and the harsh environment of the construction site. In its design and manufacturing, this hose strives to achieve a balance between strength and flexibility—it must have sufficient strength to withstand the instantaneous pressure impact that may occur during pumping blockage, while maintaining appropriate weight and flexibility for easy dragging and installation by on-site workers, truly realizing the product concept of "strong, durable, and easy to operate.
High-Rise Building Concrete Pouring: Suitable for vertical conveying and horizontal placement of concrete in the main structure construction of high-rise buildings, connecting concrete pump trucks to the formwork pouring surface, and is an indispensable key link in pumping construction.
Tunnel and Mine Lining Shotcreting: Used for initial support shotcrete construction after tunnel excavation, as well as shotcrete and anchor support operations in mine roadways and underground caverns, capable of conveying dry or wet shotcrete.
Large Foundation and Floor Construction: Suitable for large-volume concrete projects requiring long-distance or large-area placement, such as large equipment foundation pouring, industrial plant floor construction, and dockyard concrete paving.
Hydraulic and Bridge Engineering: Used for dam pouring, riverbank protection, bridge piers and box girder concrete construction, enabling precise concrete delivery and placement under complex terrain conditions.
Precast Component Production: Suitable for concrete placement systems in precast concrete component plants, used for pouring precast floor slabs, beams, columns, segments, and other concrete products into various molds. Plaster and Mortar Transportation: In addition to concrete, this hose is also suitable for pressure transportation of building plaster, wall plastering mortar, underfloor heating backfill materials, and special grouting materials.
Ultra-High Strength Explosion-Proof Design: Utilizing a four-layer high-strength steel wire spiral winding reinforcement structure, its safety factor far exceeds conventional requirements. Even in the event of a sudden pressure surge due to blockage, it effectively prevents hose rupture, ensuring the safety of construction personnel and equipment.
Excellent Wear Resistance and Service Life: The inner layer uses special high-strength NR/BR synthetic rubber, specifically designed to resist the high-speed abrasion of sand and gravel aggregates in concrete. The smooth and tough inner wall significantly extends the hose's service life under heavy wear conditions.
Lightweight and Flexible Balance: Optimizing materials and structure while ensuring strength, the hose maintains a moderate weight and good flexibility. Its reasonable bending radius makes on-site dragging, coiling, and pipe laying easier, reducing worker labor intensity.
Optimized Smooth Inner Wall Delivery: Manufactured using a mandrel forming process, ensuring a smooth, bubble-free, and wrinkle-free inner wall effectively reduces concrete conveying resistance, lowers the risk of pipe blockage, and improves pumping efficiency and continuity.
Reinforced End Fatigue-Resistant Design: The hose joints at both ends are specially reinforced to withstand frequent disassembly, bending, and pulse pressure impacts, preventing premature fatigue cracking at the joints and improving overall reliability.
Weather-Resistant Outer Layer for Harsh Working Conditions: The outer rubber layer possesses excellent UV resistance, ozone resistance, and abrasion resistance, enabling it to withstand the harsh environments of construction sites, including sun, rain, and sand/gravel friction, extending the overall service life of the hose.
Comprehensive Specifications and Flexible Customization: Available in various inner diameters from 2 inches to 5 inches, with standard lengths covering 12 feet, 25 feet, and 50 feet. Non-standard lengths can be customized to meet specific project needs, and different types of fittings are available to meet the requirements of various concrete pump trucks and trailer pumps.

Q1: What type of concrete can this Concrete Pump Hose handle?
This hose is specifically designed for pumping a wide variety of concrete mixtures, including standard structural concrete, lean concrete, shotcrete, grout, and lightweight aggregate mixes. It handles both wet-mix and dry-mix applications commonly found in construction and civil engineering projects.
Q2: What is the working temperature range of the hose?
The Concrete Pump Hose operates effectively within a temperature range of approximately -40°C to +70°C . This range accommodates both cold weather construction and the heat generated by friction during high-pressure concrete pumping operations.
Q3: Is this hose suitable for both suction and discharge applications?
This hose is primarily designed for high-pressure discharge applications in concrete placement. While it offers excellent pressure resistance, it is not typically used for suction applications. For specific vacuum or grout pumping requirements, please consult our engineering team for appropriate recommendations.
Q4: What are the available sizes and pressure ratings?
The hose is available in standard inner diameters commonly used in concrete pumping, typically from 51 mm to 152 mm . Working pressure ratings vary by size and construction, generally 85 bar (1230 psi). Custom sizes and pressure specifications are available upon request.
Q5: Can the hose be supplied with different end fittings?
Yes, the hose can be customized with various end connections to suit concrete pump equipment, including heavy-duty grooved couplings, clamp-type fittings, flanged ends, and quick-release couplings. All fittings are designed to withstand the high pressures and abrasive nature of concrete pumping.
