D3522 Grout Mixer Pump: A Durable Squeeze Pump for High-Performance Construction Applications

D3522 Grout Mixer Pump – Efficient Mixing and Reliable Pumping in One Compact Unit

The D3522 Grout Mixer Pump is a powerful all-in-one solution designed for contractors who require dependable mixing and pumping equipment for demanding construction projects. Combining a high-capacity hydraulic mixer with a proven Squeeze Pump system, the D3522 delivers smooth material flow, low maintenance, and exceptional reliability.

Engineered for grout, mortar, cementitious materials, and specialty mixes, the D3522 is ideal for infrastructure, commercial construction, foundation repair, and industrial applications where efficiency and consistent performance are essential.

Advanced Squeeze Pump Technology

At the heart of the D3522 is a 2-inch hydraulic Squeeze Pump that provides infinitely variable pumping speeds from 0 to 6 cubic yards per hour (YPH). Unlike piston pumps that contain multiple wear components, the squeeze pump operates by compressing a durable rubber pumping tube, creating a smooth and continuous flow of material.

This simple yet effective design offers several advantages:

Consistent pumping performance
Reduced maintenance requirements
Lower operating costs
Gentle handling of abrasive materials
Easy replacement of the pumping tube in approximately 20 minutes

These features make the D3522 an excellent choice for contractors seeking dependable equipment with minimal downtime.

High-Capacity Hydraulic Mixing System

The D3522 includes a 9 cubic foot hydraulic spiral mixer that produces uniform material blends for improved pumping performance. The hydraulic dump mechanism allows operators to transfer mixed material quickly into the receiving hopper, helping maintain continuous workflow on the job site.

The machine also features a 12 cubic foot receiving hopper equipped with a hydraulic agitator. This keeps grout and mortar moving smoothly, reducing the risk of material separation or blockages during pumping.

Reliable Power for Demanding Jobs

The standard configuration is powered by a 29 HP Kubota V1505 water-cooled diesel engine, delivering dependable performance in challenging construction environments. For projects where electric operation is preferred, the D3522 is also available with a 20 HP electric motor complete with starter and disconnect.

These power options provide flexibility for both outdoor construction sites and indoor industrial applications.
