D3522 Variable Speed Concrete Pump for Precise Material Delivery
The D3522 Variable speed concrete pump is a versatile and efficient solution designed for contractors who require accurate material control, reliable pumping performance, and easy transportation. Combining a hydraulic squeeze pump with an integrated spiral mixer, the D3522 Mixer/Pump provides a complete system for mixing and pumping concrete, grout, mortar, and other construction materials.
As advanced Compact concrete pumping equipment, the D3522 is designed to deliver powerful performance in a smaller, mobile package. Its compact design, flexible output control, and durable construction make it ideal for a wide range of construction applications.
Variable Speed Pumping for Maximum Control
The D3522 features a 2-inch hydraulic squeeze pump with an infinitely variable speed system that allows operators to adjust output from 0 to 6 cubic yards per hour (YPH).
This variable speed capability provides several benefits:
Precise material placement
Reduced material waste
Better control for different applications
Smooth pumping operation
Improved job-site efficiency
The hydraulic squeeze pump uses a durable rubber pumping tube as the primary wear component. The tube can be replaced in approximately 20 minutes, helping minimize downtime and maintenance costs.
Compact Concrete Pumping Equipment with Integrated Mixer
The D3522 is more than a standard pump—it combines mixing and pumping functions in one compact machine. The integrated 9 cubic foot hydraulic spiral mixer produces consistent material blends for reliable pumping performance.
The mixer includes:
Hydraulic dump system
Clean-out door for easy servicing
Efficient spiral mixing action
Fast material transfer
The 12 cubic foot receiving hopper features a hydraulic agitator that maintains continuous material movement and helps prevent separation before pumping.
Durable Construction and Reliable Power
Designed for demanding construction environments, the D3522 is powered by a dependable 29 HP Kubota V1505 water-cooled diesel engine. This reliable power source delivers consistent performance during long working hours.
For projects requiring electric operation, an optional 20 HP electric motor with starter and disconnect is available.
The power options provide flexibility for:
Remote construction sites
Commercial projects
Industrial applications
Indoor installations
Trailer-Mounted Design for Easy Mobility
The D3522 Mixer/Pump is installed on a high-speed single-axle trailer with lights and an electric braking package, making it easy to transport between job locations.
The compact trailer-mounted design offers:
Quick transportation
Easy setup
Reduced equipment handling
Better access to limited work areas
Increased job-site flexibility
An optional dual axle configuration is available for additional stability.
