Concrete Pump Hose is a heavy-duty hose uniquely formulated for pumping concrete, fireproofing, plaster, shotcrete and grout materials. This abrasion resistant heavy-wall pump hose is offered in a wide variety of sizes and end configurations. Also known as plaster-grout hose, or mud hose, concrete placement hose assemblies include full-flow internally expanded couplings. This coupling type prevents material build up around the inside hose shank and allows for higher shank retention and an increased working pressure rating. Large diameter placement hose assemblies include true bore crimp couplings.

How to Select the Right Concrete Pump Hose Size
Hose Size
Typical Application
2"
Grout transfer, mortar pumping, residential construction
2.5"
Small commercial concrete pumping
3"
Shotcrete and medium-volume pumping
4"
Boom pumps and commercial construction
5"–6"
High-volume pumping, tunnels, bridges, and infrastructure projects
Selecting the proper hose diameter helps improve pumping efficiency, reduce pressure loss, and extend hose service life. The ideal size depends on the pumping equipment, material characteristics, and project requirements.
Concrete Pump Hose Applications by Equipment Type
Different concrete pumping systems require hose assemblies designed to match their operating pressure, flow rate, and application requirements.
Boom Pump Hose
Used on truck-mounted boom pumps for high-rise buildings, bridges, large commercial projects, and infrastructure construction where precise concrete placement is required.
Line Pump Hose
Suitable for long-distance concrete delivery in residential construction, foundations, slabs, and projects with restricted site access.
Shotcrete Hose
Designed for shotcrete and sprayed concrete applications in tunnels, mining operations, slope stabilization, and underground construction projects.
Grout & Mortar Pump Hose
Used for grout injection, plaster transfer, fireproofing materials, and cement-based slurry pumping where flexibility and abrasion resistance are essential.
Concrete Placement Hose vs Concrete Delivery Hose
Although the two terms are often used interchangeably, they may refer to different stages of the concrete pumping process.
