Reliable shotcrete repair equipment is important for contractors working on concrete repair, restoration, rehabilitation, and specialty construction projects. The D3522 Pump is a compact 2-inch hydraulic squeeze pump designed for a range of suitable applications, including concrete repair, epoxy, block fill, plaster, and stucco.
With variable output from 0 to 6 cubic yards per hour and pumping pressure up to 400 PSI, the D3522 provides a flexible pumping solution for contractors looking for compact concrete rehabilitation equipment.
What Is the D3522 Pump?
The D3522 is a compact 2-inch hydraulic squeeze pump driven by a heavy-duty planetary gearbox. It features a 6 cubic foot receiving hopper and a 2-inch HD discharge.
The variable-speed pumping system provides output from 0–6 cubic yards per hour, allowing operators to adjust material delivery according to project requirements.
The machine can be configured as a trailer-mounted unit or as a lower-profile skid-mounted machine, giving contractors flexibility for transportation and job-site setup.
D3522 for Concrete Rehabilitation
Concrete rehabilitation projects often require equipment capable of supporting controlled material placement in repair and restoration work. The D3522 can be considered as part of concrete rehabilitation equipment for suitable materials and applications.
Its compact design and variable output can provide flexibility for repair contractors working on different project sizes. The machine can support suitable concrete repair applications as well as other compatible construction materials.
Before using the D3522 for a specific rehabilitation material, contractors should verify material compatibility and the required pumping specifications.
Shotcrete Repair Equipment and the D3522
When selecting shotcrete repair equipment, it is important to match the pumping machine to the specific material, application method, aggregate size, required output, and pumping requirements.
The D3522 is a 2-inch hydraulic squeeze pump intended for concrete repair and other applications listed by the manufacturer. Contractors considering it for a shotcrete-related repair application should confirm that the specific material and application method are compatible with the equipment.
This distinction is important because not every concrete repair or shotcrete material is suitable for every pump configuration.
