Efficient material handling depends on maintaining a consistent flow from mixing to pumping. The Blastcrete D6528 Mixer/Pump brings these stages together with a hydraulic spiral mixer, hydraulic agitator hopper, and 3 inch hydraulic squeeze pump.
Designed for field batching and pumping, the D6528 can handle output of up to 12 cubic yards per hour. The integrated system is a popular solution for gypsum flooring applications and provides contractors with a practical way to mix, manage, and pump compatible materials at the job site.
D6528 Material Handling System
The D6528 is built around three primary material-handling stages:
Mixing — A 9 cubic foot hydraulic spiral mixer prepares the material.
Receiving and agitation — A 12 cubic foot receiving hopper with hydraulic agitator manages the mixed material.
Pumping — A 3-inch hydraulic squeeze pump transfers the material toward the application area.
This arrangement creates a direct material path from field batching through pumping.
12 Cubic Foot Hydraulic Agitator Hopper
The hydraulic agitator hopper is an important component of the D6528 material-handling system. The receiving hopper has a capacity of 12 cubic feet and is equipped with a hydraulic agitator.
After the 9 cubic foot mixer completes its mixing cycle, the material is hydraulically dumped into the receiving hopper. The hopper then serves as the transition point before the material enters the squeeze pump.
The hydraulic agitator helps manage material within the hopper as it moves toward the pumping system.
Main Hopper Features
The D6528 receiving hopper provides:
12 cubic foot capacity
Hydraulic agitator
Direct discharge from the hydraulic mixer
Material feed to the squeeze pump
Integrated operation with the mixer and pump
The larger hopper capacity provides an intermediate material-handling stage between mixing and pumping.
How the Hydraulic Agitator Hopper Works
The material flow through the D6528 can be summarized as:
9 cubic foot mixer → hydraulic dump → 12 cubic foot hopper → hydraulic squeeze pump
After mixing, the hydraulic dump transfers material into the hopper. The hydraulic agitator assists with material management before the material moves into the pump.
This integrated arrangement allows the D6528 to handle field batching and pumping with one machine rather than requiring separate equipment for each stage.
3 Inch Hydraulic Squeeze Pump
The 3 inch hydraulic squeeze pump is the pumping component of the D6528. It receives material from the hopper and transfers it toward the application area.
The pump is driven by a heavy-duty planetary gearbox and provides variable-speed operation from 0 to 12 cubic yards per hour.
The variable output allows the operator to adjust the pumping rate according to the requirements of the project and operating conditions.
The D6528 also uses pumping tubes designed for long service life, supporting repeated pumping operations.
Why the Pump and Hopper Work Together
The relationship between the hydraulic agitator hopper and squeeze pump is important to the D6528's overall operation.
The hopper provides the space needed to receive material from the mixer, while the hydraulic agitator helps manage the material before pumping. The 3-inch squeeze pump then moves the material from the hopper toward the installation area.
This creates a coordinated sequence:
Mix → Dump → Agitate → Pump
By combining these functions into one equipment package, the D6528 provides a streamlined approach to field material handling.
9 Cubic Foot Hydraulic Spiral Mixer
Before material reaches the hydraulic agitator hopper, it is prepared in the D6528's 9 cubic foot hydraulic spiral mixer.
The mixer features:
9 cubic foot capacity
Hydraulic spiral mixing
Hydraulic dump
Clean-out door
Once the mixing process is complete, the hydraulic dump allows the material to be transferred directly into the receiving hopper.
This direct discharge eliminates the need for manual material movement between the mixer and hopper.
D6528 Output Capacity
The D6528 provides variable pumping output from 0 to 12 cubic yards per hour.
Actual production can depend on material characteristics, mix requirements, pumping configuration, hose arrangement, distance, elevation, and job-site conditions. Contractors should evaluate these factors when planning a pumping operation.
The variable-speed system gives operators flexibility in managing material delivery within the machine's rated capacity.

D6528 for Gypsum Flooring
The D6528 is a popular solution for gypsum flooring applications. Its combination of a hydraulic spiral mixer, receiving hopper with hydraulic agitator, and squeeze pump allows contractors to batch and pump compatible gypsum flooring materials.
The integrated system can help organize the workflow from material preparation through pumping.
For any specific gypsum product, contractors should follow the manufacturer's instructions for material preparation, mixing, pumping, application, and curing.
Benefits of a Hydraulic Agitator Hopper
A hydraulic agitator hopper can serve several important functions within a mixer/pump system.
Material Receiving
The hopper receives material directly from the mixer after the hydraulic dump cycle.
Intermediate Capacity
The 12 cubic foot capacity provides a dedicated stage between mixing and pumping.
Material Management
The hydraulic agitator helps manage material within the hopper before it enters the squeeze pump.
Integrated Pump Feeding
The hopper feeds the material toward the 3-inch hydraulic squeeze pump as part of the overall equipment system.
Benefits of a 3 Inch Hydraulic Squeeze Pump
The D6528's 3 inch hydraulic squeeze pump provides a dedicated pumping stage for material transfer.
Its key characteristics include:
3-inch pump configuration
Hydraulic operation
Heavy-duty planetary gearbox drive
Variable output from 0 to 12 cubic yards per hour
Pumping tubes designed for extended service
These features make the pump an important part of the D6528's field batching and pumping configuration.
Maintenance and Cleaning
Regular cleaning and maintenance are essential for equipment that handles pumpable materials.
The D6528 includes a mixer clean-out door to assist with cleaning after mixing. Operators should also inspect the receiving hopper, agitator, squeeze pump, pumping tubes, and hydraulic components according to the manufacturer's recommended maintenance procedures.
Proper cleaning can help reduce material buildup and support reliable equipment performance.
