Efficient equipment maintenance is an important consideration for contractors working on demanding epoxy grouting projects. The Blastcrete D3522 Attachment is designed for hot epoxy grouting contractors who already have compatible hydraulic power units and need a practical pumping solution.
The D3522 provides variable-speed pumping from 0 to 6 cubic yards per hour and delivers up to 400 PSI pumping pressure. Its simple 2-inch hydraulic squeeze pump, heavy-duty planetary gearbox, and design that keeps epoxy material away from moving pump components make it a useful option for contractors looking for a low maintenance epoxy grout pumping system.
What Is the D3522 Attachment?
The D3522 Attachment is a hydraulic-powered epoxy grout pump designed specifically for hot epoxy grouting applications.
Instead of requiring a separate power source, the attachment can be coupled to a compatible hydraulic power unit. This makes the D3522 particularly suitable for contractors who already own hydraulic equipment.
Important features include:
2-inch hydraulic squeeze pump
Heavy-duty planetary gearbox
Variable-speed pumping
0–6 cubic yards per hour output capacity
Up to 400 PSI pumping pressure
Long-lasting pumping tubes
10 GPM hydraulic oil requirement at 3,000 PSI
Low Maintenance Epoxy Grout Pumping System
A low maintenance epoxy grout pumping system can help contractors simplify routine equipment care and reduce unnecessary downtime.
The D3522 is designed with a straightforward squeeze-pump configuration. One notable feature is that the epoxy material does not come into contact with the moving parts of the pump.
Keeping epoxy away from moving mechanical components can be an important design consideration when evaluating pumping equipment for hot epoxy grouting.
As with any professional pumping equipment, regular inspection, cleaning, and replacement of wear components should be performed according to the manufacturer's recommendations.
Simple Hydraulic Squeeze Pump
The D3522 uses a 2-inch hydraulic squeeze pump driven by a heavy-duty planetary gearbox.
The simple pumping configuration is intended to provide dependable material delivery while keeping the pump design straightforward.
For contractors evaluating a low-maintenance epoxy pumping solution, a simple pump configuration can make routine inspection and servicing easier to manage.
Epoxy Does Not Contact Moving Parts
One of the most notable design features of the D3522 is that epoxy material does not come into contact with the moving parts of the pump.
This design separates the pumped material from the pump's mechanical components.
For hot epoxy grouting contractors, this can be an important consideration when evaluating equipment longevity, maintenance requirements, and overall pumping-system design.
Long-Lasting Pumping Tubes
The D3522 is equipped with long-lasting pumping tubes.
Pumping tubes are an important component of squeeze-pump systems because they directly participate in material delivery. Their condition should be monitored as part of normal equipment maintenance.
The use of long-lasting pumping tubes can be beneficial for contractors performing recurring epoxy grouting work.
Variable-Speed Pumping
The D3522 provides variable-speed pumping from:
0–6 cubic yards per hour
This allows contractors to adjust material delivery within the pump's rated operating range.
Variable-speed operation can help accommodate different project requirements and material delivery rates.
The appropriate pumping speed should always be selected according to the grout material, project conditions, and manufacturer's recommendations.
Up to 400 PSI Pumping Pressure
The D3522 provides up to:
400 PSI pumping pressure
This pressure capability is designed for compatible professional hot epoxy grouting applications.
The maximum pressure should not be treated as the required operating pressure for every job. Contractors should determine the appropriate pressure based on the material specifications and project requirements.
Hydraulic Power Requirements
The D3522 is designed to operate with a compatible hydraulic power unit requiring:
10 GPM @ 3,000 PSI
Before connecting the attachment, contractors should verify that their hydraulic power unit meets the specified flow and pressure requirements.
Proper hydraulic compatibility is essential for operating the equipment within its intended specifications.
