Clarify Project Needs: Determine Core Performance Parameters
The first step in selecting a small size portable diesel concrete mixer with pump is to clarify the specific needs of the construction project, which directly determines the core performance parameters of the equipment to be selected. Firstly, it is necessary to confirm the project scale and construction volume. For small-scale projects such as rural self-built houses with a daily concrete demand of 10-50 cubic meters, a small concrete pump with a mixing capacity of 3-6 cubic meters per hour and a pumping capacity of 10-30 cubic meters per hour can meet the needs; for road maintenance or small municipal projects with relatively large construction volume, it is recommended to select equipment with higher mixing and pumping efficiency to ensure the progress of the project.
Secondly, it is necessary to consider the construction environment and conveying requirements. If the construction site is located in remote rural areas with uneven terrain and poor road conditions, the small size portable diesel concrete mixer with pump must have excellent off-road performance, such as large-diameter tires, strong suspension system, and compact body design to facilitate movement in narrow and complex areas. In terms of conveying requirements, it is necessary to confirm the maximum conveying height and horizontal distance. For example, when constructing multi-storey rural houses, the equipment’s vertical pumping height should be at least 15-20 meters to meet the construction needs of upper floors. In addition, the type of concrete to be used (such as ordinary concrete, lightweight aggregate concrete) also needs to be considered, as different concrete types have different requirements for the mixing blade design and pumping system of the equipment.
Evaluate Core Components Quality: Ensure Equipment Reliability
The quality of core components is the key to ensuring the stable operation of small size portable diesel concrete mixer with pump, and it is also an important criterion for distinguishing high-quality equipment from inferior products. As a type of small concrete pump, its core components mainly include diesel engine, mixing system, pumping system, and hydraulic system. Firstly, the diesel engine is the power source of the equipment, and its quality directly affects the power, fuel efficiency, and service life of the equipment. It is recommended to select equipment equipped with well-known brand diesel engines (such as Yuchai, Changchai, Kubota) with reliable quality and mature technology. These engines have strong power, low fuel consumption, and good durability, and their after-sales service network is relatively perfect, which is convenient for later maintenance and spare parts replacement.
Secondly, the mixing system needs to have good mixing uniformity and stability. The mixing blade should be made of high-strength wear-resistant steel, and the blade structure should be scientifically designed to ensure that the concrete is fully mixed without dead corners. At the same time, the mixing drum should have good sealing performance to prevent concrete leakage during the mixing process. The pumping system is another core component, including the pump body, conveying cylinder, and concrete piston. These parts need to have strong wear resistance and pressure resistance to adapt to the long-term conveying of concrete. It is recommended to select equipment with a pumping system made of high-quality alloy materials and equipped with a pressure protection device to avoid system damage caused by excessive pressure. In addition, the hydraulic system, which controls the operation of the mixing and pumping mechanisms, should have good stability and anti-leakage performance. The hydraulic oil pump, valve, and pipeline should be of reliable quality to ensure the smooth operation of the equipment.
Focus on Portability and Maneuverability: Adapt to Complex Construction Sites
Portability and maneuverability are the core advantages of small size portable diesel concrete mixer with pump, so these two characteristics should be focused on during the selection process.

Secondly, maneuverability is reflected in the equipment’s own movement ability and operation flexibility. Equipment equipped with a self-propelled chassis and steering system can move freely on the construction site without relying on external traction, which greatly improves construction efficiency. The steering system should be flexible and sensitive, and the operation should be simple and convenient, so that operators can easily control the equipment to move to the designated construction position. In addition, the mixing and pumping operations of the equipment should be easy to operate, and the control panel should be intuitive and clear, with clear markings and simple operation procedures, which is convenient for operators with little experience to get started quickly. For some complex construction environments, it is also recommended to select equipment with adjustable supporting legs, which can ensure the stability of the equipment during operation on uneven ground.
Consider Fuel Efficiency and Operation Cost: Improve Economic Benefits
For small and medium-sized construction teams and individual operators, the operation cost of equipment is an important factor affecting the overall economic benefits of the project. Therefore, when selecting a small size portable diesel concrete mixer with pump, it is necessary to fully consider fuel efficiency and subsequent operation and maintenance costs. Firstly, fuel efficiency is directly related to the daily operation cost of the equipment. Under the same working conditions, equipment with high fuel efficiency can save a lot of diesel costs. When selecting, it is possible to compare the fuel consumption parameters of different models provided by manufacturers, and consult the actual fuel consumption feedback of existing users. Generally, a high-quality small concrete pump of this type has a fuel consumption of 3-8 liters per hour under normal working conditions, which is more economical and energy-saving.
Secondly, the subsequent operation and maintenance costs include the cost of wearing parts replacement, maintenance fees, and spare parts supply. It is recommended to select equipment with a mature structure and common wearing parts, such as mixing blades, concrete pistons, and sealing rings, which can be easily purchased in the market at a reasonable price. The maintenance of the equipment should be simple and convenient, and the manufacturer should provide a detailed maintenance manual to guide operators to carry out daily maintenance work, reducing the frequency of professional maintenance and maintenance costs. In addition, it is necessary to consider the service life of the equipment. High-quality equipment has a longer service life, which can reduce the frequency of equipment replacement and improve the overall cost-effectiveness. When selecting, it is possible to compare the service life commitments of different manufacturers and the quality of after-sales service to ensure that the equipment can operate stably for a long time.
