Choosing the right gypsum underlayment mixer pump is important for contractors who need consistent mixing, dependable pumping, and efficient material handling on flooring projects. The Blastcrete D6528 Mixer/Pump combines a hydraulic mixer and squeeze pump in one field-ready unit, making it a practical choice for gypsum flooring and underlayment applications.
Designed for field batching and pumping, the D6528 can deliver material at a variable rate of 0 to 12 cubic yards per hour. Its integrated mixing and pumping system helps contractors move material efficiently from batching through pumping and placement.
What Is a Gypsum Underlayment Mixer Pump?
A gypsum underlayment mixer pump is designed to mix gypsum-based flooring materials and then pump the prepared material to the application area. Combining these functions into one machine can simplify job-site operations and reduce the need for separate mixing and pumping equipment.
The D6528 features a 9 cubic foot hydraulic spiral mixer that hydraulically dumps the mixed material into a 12 cubic foot receiving hopper. From the hopper, the material is transferred through a 3-inch hydraulic squeeze pump.
With variable-speed pumping from 0 to 12 cubic yards per hour, operators can adjust material output to suit the requirements of the flooring project.
D6528 Gypsum Concrete Mixer Pump
The D6528 gypsum concrete mixer pump is built for field batching and pumping applications where dependable material handling is required. Its hydraulic system integrates the mixer, receiving hopper, agitator, and pump into a single equipment package.
The 9 cubic foot mixer provides the mixing capacity, while the 12 cubic foot receiving hopper provides additional material capacity before pumping. The hydraulic agitator in the hopper helps manage material as it moves toward the pump.
This configuration makes the D6528 suitable for contractors working with gypsum flooring materials and other compatible pumpable materials.
Key Features of the D6528 Mixer/Pump
The D6528 includes several features designed to support efficient field operation:
9 cubic foot hydraulic spiral mixer
Hydraulic mixer dump system
Mixer clean-out door
12 cubic foot receiving hopper
Hydraulic hopper agitator
3-inch hydraulic squeeze pump
Heavy-duty planetary gearbox drive
Variable pumping speed from 0 to 12 cubic yards per hour
Pumping tubes designed for long service life
Configuration focused on reducing pumping equipment ownership and operating costs
These features provide contractors with an integrated solution for mixing and pumping gypsum flooring materials.
Why Use a Gypsum Concrete Mixer Pump?
A dedicated gypsum concrete mixer pump can help streamline the workflow on flooring projects. Instead of transporting mixed material manually between separate machines, the D6528 handles mixing, receiving, and pumping as part of one system.
The hydraulic mixer prepares the material before dumping it into the receiving hopper. The hopper's hydraulic agitator then helps maintain material flow toward the squeeze pump.
This integrated process can be particularly useful on projects where continuous material delivery and controlled pumping are important.
D6528 Production Capacity
The D6528 has an output capacity of 0 to 12 cubic yards per hour. Its variable-speed pump allows the operator to control the pumping rate according to job requirements.
Production requirements can vary depending on material characteristics, pumping distance, application conditions, and job-site setup. The variable-speed capability gives contractors flexibility when managing material delivery.

Power Options for the D6528
The D6528 can be configured with either diesel or electric power.
Kubota Diesel Engine
The diesel configuration uses a Kubota V1505 29 HP water-cooled diesel engine. This option can provide a practical power solution for field operations where electrical power may not be readily available.
Electric Motor
An alternative configuration is a 30 HP electric motor with starter and disconnect. This option may be suitable for job sites where an appropriate electrical supply is available.
Contractors can select the power configuration that best matches their equipment fleet and project conditions.
Available D6528 Options
The D6528 can also be equipped with additional options to support different job-site requirements.
Available options include:
Pendant or wireless remote
150-gallon water tank with 2-inch flow meter
Mounted spare tire
Hydraulic pressure washer
Dual axles
Mounted air compressor
These options allow contractors to configure the gypsum underlayment mixer pump according to their operational needs.
Gypsum Flooring Applications
The D6528 is a popular solution for gypsum flooring applications because it combines mixing and pumping capabilities in one machine. For contractors involved in gypsum underlayment work, having a dedicated mixer pump can help simplify material handling and pumping operations.
The machine's hydraulic spiral mixer, receiving hopper, and squeeze pump work together as an integrated system. Its variable pumping capacity also gives operators greater control over material delivery.
Before using any mixer/pump, contractors should verify that the machine configuration, material mix, pumping setup, and accessories are appropriate for the specific application.
Maintenance and Job-Site Efficiency
Reliable equipment performance depends not only on machine design but also on proper operation and maintenance. The D6528 includes a mixer clean-out door, which is designed to assist with cleaning after operation.
The hydraulic squeeze pump and pumping tubes should be maintained according to the manufacturer's recommendations. Proper cleaning, inspection, and routine maintenance can help keep the equipment operating efficiently and extend component service life.
D6528: A Complete Gypsum Mixer Pump Solution
For contractors searching for a gypsum concrete mixer pump or gypsum underlayment mixer pump, the D6528 offers an integrated approach to field batching and pumping.
Its combination of a 9 cubic foot hydraulic spiral mixer, 12 cubic foot receiving hopper, hydraulic agitator, and 3-inch squeeze pump provides a complete material handling system. With output ranging from 0 to 12 cubic yards per hour, the machine is designed to accommodate a variety of field production requirements.
