Concrete Mixer Pump

A concrete mixer pump combines concrete mixing with pipeline conveying in one equipment package. It can be considered where a project needs to prepare concrete at the site and move it to a placement point that is not convenient for direct discharge.

The EPDAS range here covers DJBT50-10-85, DJBT40-10-82, DJBT30-08-76 and EJBT30-08-37. Their theoretical pumping outputs are 48, 40, 32 and 30 m³/h respectively. Three configurations use diesel engines; the EJBT model lists a 37 kW electric motor.

Pump displacement and mixing production are different measures. A theoretical pumping value cannot be used as the hourly output of the complete mixing-and-placement operation.

Materials must first be proportioned for the intended concrete. The mixer combines those ingredients, after which the pumping system transfers suitable concrete into the delivery line. Placement follows the supply rate and the requirements at the discharge point.

The process depends on the loading and mixing cycle as well as the pump. If mixed concrete is not available at the required rate, a higher theoretical pump output will not create extra supply.

This describes the general equipment role. Charging, starting, cleaning and intervention procedures must follow the supplied manual and trained operator arrangements.

The source lists theoretical horizontal distances of 200–250 m and heights of 50–70 m across the models. These are separate comparison entries, not a promise to achieve both maxima together on an arbitrary route.

Pipeline length, bends, elevation and the concrete itself affect the pumping requirement. Have the planned line and concrete assessed for the selected configuration; the table is not a pipeline design or a pressure-loss calculation.

The table lists a maximum aggregate size of 35 mm and slump of 160–220 mm. These are equipment-source entries, not a complete mix design. Aggregate grading, consistency and the project’s concrete requirements still need review.

Do not add water merely to make material easier to pump without the concrete producer’s approval. Maintain material measurement and quality checks through loading, mixing and placement. An integrated machine does not replace that quality process.

Assess electricity or fuel needs for the actual equipment, together with the working environment. Diesel and electric packages have different site requirements; neither removes the need for a suitable setup.

Plan where washout, residual concrete and cleaning water will be managed. The supply and placement operation needs enough space to finish the work and clean the equipment under the approved site arrangements.

The mixer, pumping components and delivery line have distinct inspection and maintenance needs. Automatic lubrication does not eliminate checks of wear parts, hoses, couplings and the other components identified in the manual.

Confirm operating documentation, training, spares and support scope with EPDAS. The general description does not fix a maintenance interval, delivery date, warranty duration or response time.

Compare the machine with its power connection, loading resources, delivery line and cleaning arrangements. A useful purchase comparison includes the work required to keep concrete arriving at the pump and being placed at the outlet.

Pipe diameter and a source-listed pipe length do not define the complete included delivery package. Confirm quantities, wear items and accessories in the order instead of treating theoretical distance as supplied pipe length.
