As a production technician at Haomei Machinery, I deeply understand the core value of concrete mixer pumps in engineering construction—they integrate concrete mixing and pumping, significantly improving construction efficiency. I will provide a professional analysis from three aspects: model specifications, output characteristics, and core technological advantages, combined with actual engineering needs, to offer potential customers precise equipment selection references.

A scientific match between model and output is fundamental to adapting equipment to engineering requirements. Haomei Machinery focuses on the core application scenarios of concrete mixer and pump machines, resulting in two main models: the HM-JB30 (30m³/h) and the HM-JB40 (40m³/h), comprehensively covering diverse needs from small and medium-sized infrastructure projects to large-scale construction.

The HM-JB30 model emphasizes flexibility and adaptability, targeting projects with limited space and dispersed workloads, such as rural renovation and small-scale residential construction. It boasts a maximum theoretical output of 30 m³/h, equipped with a 37kW high-efficiency motor (a 66kW diesel engine is optional for scenarios without power supply), and an outlet pressure of 9MPa. It can transport concrete up to 120m horizontally and 50m vertically, and is suitable for concrete with a slump of 8-20cm, and aggregate sizes ≤30mm (crushed stone) or ≤40mm (pebbles). The overall dimensions of the equipment are 7300×2210×2580mm. This facilitates transport along narrow rural roads.

The HM-JB40 model is a general-purpose mainstay model with a maximum theoretical output of 40 m³/h. It is equipped with a 45kW electric motor or an 82kW diesel engine, increasing the outlet pressure to 10MPa and upgrading the conveying capacity to 140m horizontally and 60m vertically. It can meet the needs of large-scale construction projects such as affordable housing construction in county towns, small bridges, and tunnel lining. It uses a 600L large-capacity hopper, ensuring better feeding continuity and controlling the slurry leakage rate below 0.5%. It also supports wireless remote control, significantly reducing labor intensity. It is currently the core model with the largest export volume.

Core technological advantages are key to the stable and efficient operation of the concrete mixer pump equipment. Firstly, the high-efficiency pumping system adopts an optimized "S" pipe valve design. The gradual diameter change reduces pumping resistance by 15%. The valve body is hot-stamped and overlaid with a special wear-resistant layer, achieving a hardness of HRC60 or higher. Combined with a floating cutting ring structure, it completely solves the pressure leakage problem, increasing the lifespan of vulnerable parts by 20% compared to the industry average. Secondly, the intelligent power matching technology employs a constant-power plunger pump with stepless displacement adjustment, fully utilizing the prime mover's power and achieving 15%-20% energy savings compared to traditional equipment. It also features an automatic overpressure cut-off device to ensure system reliability. Thirdly, the integrated mixing and feeding system is driven by a high-torque hydraulic motor, supporting forward and reverse rotation to prevent jamming. Its compact sealing structure controls leakage to below 0.5%, and the 500L large-capacity hopper ensures continuous feeding. Its 1375mm ground clearance allows for unloading by standard transport vehicles.

Furthermore, the concrete mixer pump machine's ease of maintenance and environmental adaptability significantly enhance customer value. An automatic multi-point progressive lubrication system ensures precise oil supply to each lubrication point, reducing maintenance workload. The dual cooling design of air cooling and forced heat dissipation adapts to extreme construction environments from -10℃ to 45℃, meeting the climatic requirements of different countries and regions. Key seals use imported brands to eliminate cylinder leakage, and the delivery pipe cleaning supports both compressed air and high-pressure water washing modes, significantly shortening construction intervals.

Haomei's concrete mixer and pump machine, through precise positioning and iterative optimization of its two core models (30m³/h and 40m³/h), has achieved the design goals of "adapting output to demand, ensuring stable performance, and reducing operation and maintenance costs." It has obtained international certifications such as CE and ISO and is widely used in infrastructure projects in over 30 countries worldwide. When selecting equipment, we recommend matching the model to the project scale, conveying distance, on-site power conditions, and material characteristics. We can provide customized technical solutions.
