In demanding construction environments, equipment must deliver reliable performance, withstand continuous use, and minimize maintenance interruptions. The D3522 Mixer / Pump is engineered to meet these challenges with a durable pumping tube and a high-performance construction pump designed for efficient material handling. Whether you're pumping grout, mortar, shotcrete, or concrete, the D3522 provides the durability, productivity, and low operating costs that contractors depend on.
Its integrated hydraulic squeeze pump and hydraulic spiral mixer create a versatile solution for projects requiring consistent material flow and dependable operation.
Durable Pumping Tube for Long-Lasting Performance
A durable pumping tube is essential for maintaining consistent pumping efficiency while reducing maintenance expenses. The D3522 features one of the industry's longest-lasting rubber pumping tubes, designed to handle abrasive construction materials with excellent wear resistance.
Benefits of the durable pumping tube include:
Extended service life
Reliable pumping performance
Reduced maintenance costs
Smooth material flow
Simplified replacement procedure
Less jobsite downtime
As the primary wear component of the pump, the rubber pumping tube can be replaced in approximately 20 minutes, allowing operators to quickly resume work and maximize equipment availability.
High-Performance Construction Pump for Demanding Applications
The high-performance construction pump incorporated into the D3522 is built around a 2-inch hydraulic squeeze pump with infinitely variable speed control. This allows operators to precisely adjust pumping output from 0 to 6 cubic yards per hour, making it suitable for a variety of construction applications.
The hydraulic squeeze pump provides:
Consistent material delivery
Efficient hydraulic operation
Reliable pumping under demanding conditions
Lower maintenance requirements
Smooth handling of grout, mortar, concrete, and shotcrete
Its simple design and heavy-duty planetary gearbox contribute to long-term reliability and lower operating costs.
