D3522 Hydraulic Spiral Mixer Pump: A Heavy-Duty Construction Pump for Reliable Material Handling

D3522 Hydraulic Spiral Mixer Pump for Professional Construction Applications

The D3522 Hydraulic spiral mixer pump is a versatile and powerful construction solution designed to mix and pump concrete, grout, mortar, and other cement-based materials efficiently. Combining a high-performance hydraulic spiral mixer with a reliable squeeze pumping system, the D3522 Mixer/Pump delivers consistent material preparation and smooth pumping performance for demanding construction environments.

Designed as a Heavy-duty construction pump, the D3522 provides contractors with a durable, mobile, and cost-effective machine capable of handling a wide range of applications.

Advanced Hydraulic Spiral Mixing Technology

The D3522 features a 9 cubic foot hydraulic spiral mixer engineered to provide uniform mixing and consistent material quality. The spiral mixing system ensures thorough blending of materials before pumping, helping achieve better performance and reliability on the job site.

The hydraulic mixer includes:

Hydraulic dump system for fast material transfer
Clean-out door for simplified maintenance
Efficient spiral mixing action
Consistent material blending
Reduced manual handling requirements

This integrated design allows contractors to complete mixing and pumping operations using one compact machine.

Heavy-Duty Construction Pump Performance

The D3522 operates as a dependable Heavy-duty construction pump, equipped with a 2-inch hydraulic squeeze pump powered through a heavy-duty planetary gearbox. The system provides infinitely variable output from 0 to 6 cubic yards per hour (YPH).

The hydraulic squeeze pump delivers:

Smooth material flow
Adjustable pumping speed
Reliable concrete and grout handling
Reduced wear and maintenance costs
Efficient operation on demanding projects

The primary wear component is the durable rubber pumping tube, which can be replaced in approximately 20 minutes to minimize downtime.

Integrated Hopper with Hydraulic Agitation

The D3522 includes a 12 cubic foot receiving hopper equipped with a hydraulic agitator. This system maintains continuous material movement and helps prevent separation before pumping.

The agitator-equipped hopper provides:

Consistent material feeding
Improved pumping efficiency
Reduced risk of blockages
Better mix quality during operation

This feature makes the D3522 suitable for applications requiring steady and reliable material placement.

Reliable Kubota Diesel Power System

The D3522 is powered by a reliable 29 HP Kubota V1505 water-cooled diesel engine, providing strong performance for challenging construction environments.

The diesel power system offers:

Long operating life
Efficient fuel usage
Dependable performance
Consistent power delivery
Suitability for remote job sites

For projects requiring electric operation, the D3522 is also available with a 20 HP electric motor with starter and disconnect.

Mobile Trailer-Mounted Construction Design

The D3522 Mixer/Pump is mounted on a high-speed single-axle trailer with lights and an electric braking package, making transportation between job sites simple and efficient.

The mobile design allows contractors to:

Move equipment quickly between projects
Reduce setup time
Access difficult job locations
Improve job-site flexibility
Operate with minimal preparation

A dual axle option is available for additional transportation stability.
