Concrete pump hoses are used to deliver concrete slurry at the end of the line at the boom pump or stationary pump, this way improves the efficiency when compared with old traditional methods like hopper convey. Concrete pump hoses are linked at the end of the steel pipes and can be directed to any orientation because of their flexibility.
The structure of the concrete pump hose
Like most of the rubber hoses we supply, the structure of our concrete pump hoses has three layers:
- Inner tube: The inner tube is directly in touch with the concrete material, it must have abrasion resistance and is made of polybutadiene rubber, which has optimal wear resistance features when compared with other kinds of rubbers.
- Reinforcement layer: Reinforcement layer(s) offer strength for the rubber hose, premade textile fiber belts are wound around the inner tube, and even number plies are reinforced with converse direction in the neighboring layers.
- Outer cover: the outer cover is meant to protect the inner layers(reinforcements and inner tube), it has weather resistance. Due to the specific application scenarios of concrete pump hoses, natural rubbers, and SBR rubbers are optimal because of their price.
The specification of the concrete pump hoses
The specification of the concrete pump hoses is shown in the table below, they are in high-frequency in use, and the longest hoses are 60m with the limitation of the production line, but they are often cut even short for custom applications.

The manufacture of the concrete pump hose
Most industrial rubber hoses are spiral wounds on the hose-forming machine, and the fundamental procedures are:
The application of the concrete pump hose
Concrete pumps are a relatively typical sight on building sites these days. You may use modern
concrete pumping machines on both large-scale commercial projects and medium-sized building
sites, and they perform as well in both situations. Concrete pumps have replaced all other means
of delivering liquid concrete at building sites during the past few years.
At huge construction sites in the past, cranes were employed to raise big buckets full of concrete
where they were required. The crane’s limited capacity to lift one bucket at a time, which could
only contain about two cubic yards of concrete, presented the biggest obstacle.
A concrete pump is a crucial component of any construction project since it transports liquid
mixed concrete from the containers to the locations where it has to be filled at the building site.
Concrete pumps may be divided into two categories. One is referred to as a Boom Pump, or
Truck-mounted Pump, which is larger and is utilized on larger sites and for significant road and
highway construction. It typically has a truck or semi-trailer mount and is equipped with an
autonomous robotic arm that precisely places the concrete as needed.
The second kind, a Trailer, Line, or Stationary Pump, is utilized for minor tasks like preparing
sidewalks or ground slabs. It makes use of steel or flexible hoses that are connected to the
pump’s output. These hoses are connected and lead to the desired location for the concrete
placement.
Concrete pump hoses are idealistic options for the concrete pump due to their strength and flexibility, the wear-resistance of the inner hose can contribute to their lifespan in the application, furthermore, you can custom the reinforcement layer to get the working pressure you required. and you can also order the hose coupling to connect with other elements and embed it in your system, as a rubber hose manufacturer, diameter, reinforcement, materials, length even more parameters are all your options to define your requirements.
Additionally, these hoses are made and engineered to withstand even the most abrasive
substances, such as some solid materials, sand, grains, and powders, the production craft are similar if you have other requirements for industrial rubber hoses, please let me know.
