Dn125 concrete pump rubber hose

The Dn125 concrete pump rubber hose is a high-pressure delivery line designed for use in commercial and industrial concrete pumping systems. It features an inner rubber layer compounded for abrasion resistance, reinforced with four layers of steel wire braid, and an outer rubber cover rated for pressures up to 180 bar. The internal diameter is exactly 125 mm, matching standard pump outlet flanges. This hose is built for continuous operation under high shear stress and is compatible with Schwing, Sany, and Putzmeister pump systems.

The construction follows typical industry standards for pump hoses, with a working pressure range of 120 to 180 bar and a burst pressure exceeding 540 bar. The steel wire reinforcement is ASTM A228 grade, and the rubber compound is nitrile butadiene rubber (NBR) with a hardness of 70±5 Shore A. The hose is flexible enough to handle tight bends without kinking, and the outer cover resists UV degradation and oil exposure, which are standard requirements in construction environments. No certifications are stated by the supplier, but the material composition aligns with ISO 14022 for industrial rubber hoses.

This hose is purchased primarily by construction contractors, precast concrete producers, and infrastructure firms in Southeast Asia, the Middle East, and Africa. Buyers typically order in lengths of 3 or 5 meters, with bulk quantities shipped in cartons of 10 to 20 pieces. Packaging is usually in polyethylene sleeves with cardboard end caps. Trade terms are not specified, but standard Incoterms for bulk rubber goods include FOB Qingdao or CIF Port of Destination. Buyers should confirm the hose’s internal surface finish and pressure test records before shipment.
