Construction professionals need equipment that delivers reliable performance, consistent material flow, and low operating costs across a variety of applications. The D3522 Mixer / Pump is engineered as versatile shotcrete equipment and dependable grouting equipment, combining a hydraulic squeeze pump with a hydraulic spiral mixer to provide an efficient all-in-one solution for demanding jobsites.
Designed for pumping grout, mortar, shotcrete, and concrete, the D3522 offers smooth operation, easy maintenance, and the flexibility required for commercial, industrial, and infrastructure projects.
Advanced Shotcrete Equipment for Reliable Performance
As professional shotcrete equipment, the D3522 Mixer / Pump delivers precise and consistent material flow through its 2-inch hydraulic squeeze pump. The infinitely variable pumping speed allows operators to adjust output from 0 to 6 cubic yards per hour, making it suitable for both small repair jobs and large-scale construction projects.
The hydraulic squeeze pump provides several advantages for shotcrete applications:
Smooth and continuous material delivery
Reduced material segregation
Adjustable pumping speed for greater control
Reliable performance during extended operation
Simplified maintenance with fewer wear components
Its durable design helps contractors maintain productivity while reducing equipment downtime.
Efficient Grouting Equipment for Multiple Applications
The D3522 also serves as highly efficient grouting equipment, making it ideal for pumping cement grout, mortar, and other cementitious materials. The integrated hydraulic spiral mixer ensures materials are thoroughly mixed before entering the pumping system, resulting in consistent application quality.
The machine is well suited for:
Foundation grouting
Structural repair
Void filling
Tunnel construction
Bridge rehabilitation
Masonry grouting
Infrastructure maintenance
The rubber pumping tube is the primary wear component and can typically be replaced in approximately 20 minutes, helping minimize service interruptions and maintenance costs.
