The success of civil engineering and building construction projects depends on equipment that delivers consistent performance, durability, and operational efficiency. The D3522 Mixer / Pump is designed as versatile civil engineering equipment and reliable building construction machinery, combining advanced mixing and pumping capabilities into one compact, trailer-mounted solution.
Equipped with a powerful hydraulic squeeze pump, an integrated hydraulic spiral mixer, and a durable drive system, the D3522 helps contractors complete projects faster while reducing maintenance costs and equipment downtime.
Civil Engineering Equipment Built for Demanding Projects
Modern civil engineering equipment must perform reliably across a wide range of applications, from infrastructure development to structural repairs. The D3522 Mixer / Pump is engineered to handle demanding construction materials such as grout, mortar, shotcrete, and concrete with consistent efficiency.
Its 2-inch hydraulic squeeze pump features infinitely variable speed control, allowing operators to adjust the pumping output from 0 to 6 cubic yards per hour. This flexibility makes the machine suitable for projects requiring precise material placement and controlled pumping performance.
The trailer-mounted design also allows for quick transportation between multiple worksites, improving overall project efficiency.
Building Construction Machinery That Improves Productivity
As dependable building construction machinery, the D3522 combines material mixing and pumping in one integrated unit. This eliminates the need for separate equipment, helping reduce labor requirements, equipment transportation, and setup time.
The machine includes a 9 cu. ft. hydraulic spiral mixer that produces a consistent mix before transferring material to the hydraulic squeeze pump. The 12 cu. ft. receiving hopper with a hydraulic agitator ensures a continuous material supply, helping maintain steady pumping performance throughout the job.
