The D3522 Attachment for hydraulic power units is designed for hot epoxy grouting contractors who already own compatible hydraulic power equipment. Developed as a hydraulic-powered attachment, the Blastcrete D3522 provides variable-speed pumping and pressure capability for professional grouting applications.
The D3522 can be coupled to a suitable hydraulic power unit to provide variable-speed pumping from 0 to 6 cubic yards per hour and up to 400 PSI pumping pressure.
Its 2-inch hydraulic squeeze pump, heavy-duty planetary gearbox, and long-lasting pumping tubes provide a straightforward configuration for hot epoxy grouting contractors.
What Is the D3522 Attachment?
The D3522 Attachment is a hydraulic-powered pumping attachment designed for contractors who already have compatible hydraulic power units.
Instead of requiring a separate dedicated power source, the attachment can be coupled to an appropriate hydraulic power unit.
This makes the D3522 a practical option for contractors who want to use existing hydraulic equipment for hot epoxy grouting.
The system provides:
Variable-speed pumping
0–6 cubic yards per hour output
Up to 400 PSI pumping pressure
2-inch hydraulic squeeze pump
Heavy-duty planetary gearbox
Long-lasting pumping tubes
D3522 Attachment for Hydraulic Power Units
A primary advantage of the D3522 is its compatibility with contractors who already own hydraulic power units.
The specified hydraulic requirement is:
10 GPM @ 3,000 PSI
Before purchasing the D3522, contractors should verify that their existing hydraulic power unit can meet these requirements.
Proper hydraulic compatibility is essential for achieving the equipment's stated operating performance.
Variable-Speed Pumping
The D3522 provides variable-speed pumping from:
0–6 cubic yards per hour
This adjustable output allows contractors to control material delivery within the equipment's rated capacity.
Variable-speed operation can be useful when project conditions or material delivery requirements change.
The appropriate pumping rate should be determined according to the epoxy manufacturer's recommendations and the requirements of the specific project.
Up to 400 PSI Pumping Pressure
The D3522 can deliver up to:
400 PSI pumping pressure
This provides pressure capability for compatible professional hot epoxy grouting applications.
The maximum rated pressure should not automatically be considered the required operating pressure. Contractors should select operating pressure according to the material, application, and project specifications.
2-Inch Hydraulic Squeeze Pump
The D3522 features a 2-inch hydraulic squeeze pump driven by a heavy-duty planetary gearbox.
The squeeze-pump configuration provides a straightforward mechanism for pumping compatible hot epoxy and grouting materials.
This simple design is intended to provide practical operation and maintenance for professional contractors.
Heavy-Duty Planetary Gearbox
A heavy-duty planetary gearbox drives the D3522's hydraulic squeeze pump.
The gearbox provides the mechanical drive for the pumping system and contributes to the equipment's professional-duty configuration.
Combined with the long-lasting pumping tubes, the gearbox provides a robust pumping arrangement for compatible hot epoxy grouting applications.
Epoxy Material Does Not Contact Moving Parts
An important feature of the D3522 is that epoxy material does not come into contact with the moving parts of the pump.
This separates the pumped material from key mechanical components.
For contractors evaluating a D3522 Attachment for hydraulic power units, this design feature can be an important consideration when comparing different pumping systems.
Long-Lasting Pumping Tubes
The D3522 incorporates long-lasting pumping tubes designed for professional pumping applications.
Pumping tubes are an important component of a squeeze-pump system because they participate directly in material delivery.
For contractors performing frequent hot epoxy grouting work, pumping-tube durability can be an important factor when selecting equipment.

How to Evaluate a Hydraulic Power Unit for the D3522
Before connecting a D3522 Attachment to a hydraulic power unit, contractors should verify the available hydraulic specifications.
The stated requirement is:
10 GPM @ 3,000 PSI
In addition to hydraulic flow and pressure, contractors should consider:
Compatibility of hydraulic connections
Available hydraulic capacity
Epoxy material requirements
Required pumping rate
Required pressure
Jobsite conditions
Equipment placement
Application requirements
Checking these factors before operation can help ensure that the D3522 is appropriately matched with the available hydraulic equipment.
D3522 Dimensions
The D3522 Attachment has the following dimensions:
Length: 76 inches
Width: 37 inches
Height: 39 inches
Hopper charging height: 28 inches
These dimensions should be considered when planning transportation, equipment positioning, and jobsite access.
Why Choose an Attachment-Style Grout Pump?
An attachment-style pumping system can be useful for contractors who already have compatible hydraulic power equipment.
Rather than purchasing an entirely separate hydraulic power system, contractors can connect the D3522 to an appropriate existing hydraulic source.
This configuration provides access to variable-speed pumping, pressure capability, and a professional hot epoxy grouting pump without requiring a dedicated hydraulic power unit as part of the attachment itself.
