Concrete Pump Hose
Product Overview
A concrete pump hose is a specialized rubber hose engineered to transfer high-pressure concrete containing large particle aggregates from pump truck outlets to pour points. Manufactured in china under rigorous standard EN 13060, this Wire Spiral Hose defines reliability for construction sites worldwide.
The core structure integrates an antistatic NR/SBR/BR inner tube, steel cord wrapped reinforcement, and an SBR cloth-impression cover. This design resists abrasion and static buildup while maintaining flexibility under extreme pressure.
Key performance parameters include a working pressure of 8.5 MPa (1230 psi) and a burst pressure of 20 MPa (2900 psi), with a 2:1 safety factor. Temperature range spans -35°C to +80°C, suitable for diverse climates.
Core advantages: exceptional resistance to concrete wear, antistatic safety, large aggregate passage without clogging, and high-pressure integrity. Application focuses on concrete pumping with large particle aggregate at high pressures. It solves frequent hose burst, premature abrasion, and static discharge risks. Every hose is backed by quality assurance from a leading manufacturer with OEM ODM capabilities.

Structure and Materials
- Inner Tube: NR/SBR/BR blend, black, smooth bore, antistatic, abrasion resistant. Ensures uninterrupted flow of concrete slurry.
- Reinforcement: Steel cord wrapped in spiral layers – this is a true Wire Spiral Hose designed for high-pressure concrete pumping.
- Outer Cover: SBR rubber, black, antistatic with cloth impression. Resists cuts, abrasion, and weather exposure.
- Fittings: Long style full flow internally expanded fittings for high-pressure applications. Available as hose assembly with crimped fittings or reusable fittings. Adapters and flanges also supplied.
Why Steel Cord Wrapped Reinforcement?
Concrete pump hoses experience both radial expansion and axial tension. The steel cord wrapped construction balances these forces, preventing kinking and cover separation. Unlike a standard Wire Braided Hose, the spiral design delivers higher burst resistance and longer pulse life under erratic pump discharges.
Safety Factor Explained
The 2:1 safety factor (working pressure 8.5 MPa, burst 20 MPa) is conservative compared to general hydraulic hoses. This margin accounts for field abrasion, repetitive flexing, and unexpected pressure spikes – common in boom pump operations.
Application Industries
Primary Applications
- Concrete boom pumps: Transfer concrete from pump truck to high-rise formwork.
- Trailer-mounted concrete pumps: Line pumping for slabs and foundations.
- Shotcrete equipment: Tunnel linings and slope stabilization.
- Grout pumping: Pre-stressed concrete ducts.
- Industrial concrete placement: Precast plants and large-scale pours.
Precise Selection Professional Guide
It is More Than a Hose – Complete Hose Assembly Solution
A hose assembly includes the concrete pump hose plus end fittings. For high-pressure concrete applications, we recommend:
- Crimped fittings: Permanent attachment, zero leakage under pulsation.
- Reusable fittings: Field repairable, good for emergency replacements.
- Flanges: For large bore sizes (4″ to 6″), flange connections provide secure mounting.
- Protective sleeves and guards: Added abrasion resistance where hose contacts rebar or sharp edges.
Our factory produces pre-assembled hoses with 100% pressure testing. Pre-assembled hose assembly reduces installation errors and leak points compared to field assembly.
Concrete Pump Hose vs. Standard Material Handling Hose
| Feature | Concrete Pump Hose | Standard Rubber Hose |
|---|---|---|
| Reinforcement | Steel cord wrapped | Textile or light wire |
| Working pressure | 8.5 MPa | Usually below 3 MPa |
| Abrasion resistance | High (concrete slurry) | Moderate |
| Antistatic | Yes (both tube & cover) | Rare |
| Aggregate size | Up to 38mm smooth passage | Limited |
Solving On-Site Pain Points
Pain Point: Frequent burst near coupling ends
Our steel cord reinforcement and long style expanded fittings distribute stress evenly, eliminating premature failure at crimp points.
Pain Point: Static discharge shocking operators
Antistatic inner tube and cover meet safety requirements for material transfer hoses.
Pain Point: Short service life due to cover abrasion
SBR cloth-impression cover outlasts smooth covers by 3x in dragging applications.

- Use correct crimped fittings or flanges for the hose I.D.
- Install protective sleeves where hose contacts sharp edges.
- Avoid twisting during coupling – mark alignment before tightening.
Operation
- Stay within -35°C to +80°C concrete temperature range.
- Do not exceed 8.5 MPa working pressure.
- Flush hose with water after each concrete pour to prevent hardening inside bore.
Maintenance
- Inspect cover weekly for cuts or exposed reinforcement.
- Replace hose if blistering or soft spots develop.
- Store in dry, shaded area – avoid ozone and direct sunlight.
Frequently Asked Questions (FAQ)

A: A concrete pump hose is a High Pressure Hose with steel cord reinforcement, designed to transfer concrete with large aggregates at pressures up to 8.5 MPa.
Q: Can I buy this hose in bulk for a large project?
A: Yes. We supply in bulk lengths (up to 60m continuous) with wholesalediscount available for volume orders.
Q: What is the cost range compared to standard rubber hose?
A: Price is higher than textile reinforced hose but lower than custom hydraulic spiral hoses. Request a quote based on I.D. and quantity.
Q: Do you offer OEM ODM services?
A: Yes, as a producer and factory, we provide OEM ODM branding, custom printing, and special end fittings.
Q: How do I get the specification PDF?
A: Click the download button above or contact Service to request the pdf datasheet.
Q: What is the difference between Wire Spiral Hose and Wire Braided Hose for concrete?
A: Wire Spiral Hose uses counter-rotating steel cord layers for higher burst pressure and longer pulse life. Wire Braided Hose is more flexible but lower pressure – not recommended for boom pump applications.
