How Does The Concrete Mixer with Pump Work?

The concrete mixer with pump, as the name suggested, it is a piece of equipment that can mix and pump concrete mixture simultaneously when working. It is designed to simplify the concrete placement process by eliminating the need for separate equipment for mixing and pumping.

How Does a Concrete Mixer With Pump Work

By integrating mixing and pumping ability, it offers a cost-effective and time-saving solution for concrete placement, making it an indispensable tool for modern construction projects, like residential, commercial, and infrastructure developments. Here I will explain to you how the concrete mixer pump works efficiently.

Working Process of The Concrete Mixer with Pump

Compared with the trailer concrete pump, the AIMIX concrete mixer pump has an addition mixing function. Thus, it has an additional mixing process. Actually, the working process is simple. We have divided it into three steps: the mixing process, pumping process, and the cleaning and maintaining process. Let me introduce them in the following paragraphs.

Mixing Process

  • Aggregate loading: The process begins with loading the necessary aggregates (such as sand, gravel, and cement) into the concrete mixer’s hopper or drum. The proportions of these aggregates are predetermined based on the desired concrete mix.
  • Adding Water: Once the aggregates and cement are in the drum, the appropriate amount of water is added to initiate the hydration process and achieve the desired consistency. The water content is carefully controlled to ensure the strength of the concrete mixture.
  • Mixing: With all the ingredients in place, the mixer drum begins to rotate. The rotational movement facilitates the thorough blending of the aggregates, cement, and water. The constant agitation inside the drum ensures that each particle is evenly distributed throughout the mixture to ensure a homogenous blend of concrete.

Pumping Process

Priming and Preparation

Ensure the pump system is properly primed by filling it with water or a priming agent to lubricate the pipes.

Open the necessary valves and ensure the delivery line is clear of any obstructions.

Check the pump controls and pressure gauges to ensure they are functioning correctly.

Engaging the Pump

Activate the pump system by turning on the power and engaging the pump controls.

Adjust the throttle or speed control to set the desired pumping speed.

Monitor the pressure gauge to ensure the system maintains the appropriate pressure for pumping.

Concrete Loading

Load the thoroughly mixed concrete from the mixing drum into the hopper of the concrete mixing pump.

Ensure a consistent and continuous supply of concrete to the hopper to avoid interruptions during the concrete pumping process.

Use a conveyor belt, bucket, or other equipment to carry on the loading process if necessary.

Concrete Delivery

As the pump is engaged, the concrete is pushed from the mixer through the pump system. The hydraulic cylinders or pistons generate the necessary force to propel the concrete forward.

S-Valve Operation

The concrete passes through an S-valve mechanism, which consists of two flaps that open and close alternately. The S valve system ensures the concrete flows in one direction while preventing backflow.

Delivery Line Positioning

Position the delivery line, either manually or with the assistance of extension mechanisms, to reach the desired location. Ensure the delivery line is properly supported and stabilized to prevent excessive movement or sagging.

Concrete Placement

The concrete is delivered through the delivery line to the desired location on the construction site.

The operator controls the movement of the delivery line, directing the concrete precisely to the intended area.

The flow rate, pressure, and other concrete pump with mixer parameters are monitored and adjusted by the operator to ensure smooth and accurate concrete placement, avoiding excess build-up or gaps.

Pumping Control

Adjust the pumping controls to control the flow rate and pressure of the concrete.

Use the control panel or switches to regulate the speed and direction of the concrete flow.

Maintain a steady and controlled flow of concrete to ensure accurate placement.

Continuous Pumping

Continuously monitor the pumping process, including the flow rate, pressure, and concrete consistency.

Make adjustments to the pump controls, throttle, or S-valve position as necessary to optimize the pumping operation.

Address any issues or irregularities promptly to ensure smooth and efficient concrete placement.

Cleaning and Maintaining Processes

Cleaning the System After Concrete Mixer with Pump Work

Use water gun or a cleaning agent through the pump system and delivery line to remove any remaining concrete residue.

Flush the mixer drum thoroughly to remove any residual concrete and debris. Pay special attention to the interior surfaces to prevent buildup and prolong the drum’s lifespan.

The cleaning process is necessary steps after working. It can helps prevent blockages and ensures the concrete mixer pump for sale stays in good condition. For further cleaning details, please refer to this web page:

Maintenance Tips After Concrete Mixer with Pump Work


Check the pump components, delivery line, and mixer drum for any signs of damage, wear, or leaks. Address any issues promptly to prevent further damage and maintain operational efficiency.

Inspect and clean any filters or screens in the pump system to ensure proper filtration and prevent clogs that can affect performance.


Apply lubrication to moving parts such as valves, pistons, and hydraulic components to keep them operating smoothly and prevent friction-related damage.

Schedule Regular Maintenance

Establish a schedule for routine maintenance tasks such as oil changes, filter replacements, and hydraulic system checks to keep the concrete mix and pump in optimal working condition. If you want to know how to maintain concrete pump regularly, you can read the useful contents on this page:
