The pumping pressure range of JBS40 concrete mixing pump is usually between 8-13 MPa. This range is based on the common configurations and performance parameters of the pump model, but please note that the specific values may vary depending on different manufactures, batches of products and usage conditions.
In practical use, in order to ensure the smooth progress of the pumping process and the quality of concrete, operators need to flexibly adjust pumping parameters, including pumping pressure, based on factors such as the material properties of concrete, the layout and length of pumping pipeline, etc. At the same time, it is also necessary to pay attention to various indicators during the pumping process, such as the fluidity of concrete, pumping speed, etc., in order to promptly identify problems and take corresponding measures.
Overall, the pumping pressure range of JBS40 concrete mixing pump is a relatively stable range, but the specific values will be affected by various factors. Therefore, flexible adjustments should be made according to the actual situation during use, and attention should be paid to observing various changes during the pumping process. If necessary, it is recommended to refer to the product manual of this model of concrete mixing pump or contact the manufacturer for consultation to obtain more accurate information.
The maximum pumping pressure of JBS40 concrete mixing pump ( or similar models of concrete conveying pump, such as the 40 type concrete conveying pump mentioned earlier) is influenced by various factors, and the following are some of the main factors.
Characteristics of Concrete Materials
- Cement dosage
Cement is a key component in the process of concrete pumping, which can form a lubricating layer and reduce the friction between the inner wall of the conveying pipe and the concrete. The amount of cement used directly affects the pressure loss during concrete pumping.
- Stone particle size
Stones play a skeleton role in concrete, and their particle size and grading are important factors affecting the pumpability of concrete. Excessive particle size or poor grading of stones can easily cause pipeline blockage, thereby increasing pumping pressure.
- Sand and admixtures
Sand is used to fill the gaps between stones and work together with stones to form a skeleton. The grading and modulus of sand have a significant impact on the flowability of concrete mixtures. In addition, the type and amount of admixtures can also affect the pumping performance of concrete.
- Water cement ratio and slump
A high water cement ratio is beneficial for pumping concrete, but an excessively high water cement ratio can cause concrete segregation and increase the difficulty of pumping. Slump is an important indicator for evaluating and testing the pumpability of concrete. If the slump is too small, it will increase frictional resistance and reduce fluidity.
Excessive collapse can cause aggregate precipitation and affect the quality of concrete.
Pumping Pipeline And Layout
- Pipeline length and number of bends
The longer the pump pipe and the more bends there are, the greater the resistance during concrete pumping and the higher the required pumping pressure.
- Sealing of pipeline interface
Poor sealing of pipeline interface can lead to a decrease in pumping pressure, a decrease in the flow velocity of slurry concrete in the pipeline, and even cause pipe blockage.
- Pipeline wear and blockage
Long term use can cause wear on the inner wall of the pipeline, increasing pumping pressure. Meanwhile, residues or impurities in the pipeline may also cause blockages, affecting pumping efficiency.
Performance of Pumping Equipment
- Hydraulic pump performance
The output flow rate and pressure of the hydraulic pump directly affect the performance of the concrete conveying pump.
Hydraulic pump wear, incorrect steering or damaged parts can all lead to insufficient output pressure.
- Overflow valve and directional valve
The working state of these valves can also affect the pumping pressure. If the valve gets stuck or leaks severely, it will cause a short circuit between the pressure oil circuit and the overflow circuit, reducing the pumping pressure.
- Sealing Device
Damaged seals of hydraulic cylinders and motors can cause serious leakage, thereby reducing pumping pressure.
- Operational Standardization
The preparation work before pumping, the operational skills during the pumping process, and the handling methods when encountering problems all affect the pumping pressure. For example, failure to clean, lubricate, or adjust the pumping speed in a timely manner according to regulations can lead to pressure issues.
- Experience Level
The experience level of operators has a significant impact on the regulation and troubleshooting of pumping pressure. Experienced operators can better handle various pumping situations and ensure the smooth progress of the pumping process.

In summary, the maximum pumping pressure of JBS40 concrete mixing pump is determined by multiple factors such as the characteristics of concrete materials, pumping pipelines and layout, pumping equipment performance and operator skills. Therefore, in practical operation, it is necessary to comprehensively consider these factors to ensure the smooth progress of the pumping process and the stability of the pumping pressure.
