Castable refractory installation requires dependable material mixing and controlled placement to achieve efficient project execution. The Blastcrete MX-20CM Mixer/Pump combines continuous high-shear mixing with a high-pressure swing tube piston pump, providing an integrated solution for refractory placement applications.
Designed for both smaller projects and high-volume operations, the MX-20CM has a stated output range of 0–25 tons per hour, making it a practical option when consistent castable preparation and pumping capacity are important.
Refractory Pump for Castable Installation
The MX-20CM is designed to function as a refractory pump for castable installation, combining material hydration and pumping in one machine.
Its two-stage mixing system consists of a high-shear primary continuous mixer and a medium-shear secondary mixer positioned in the receiving hopper. This arrangement helps prepare the material before it enters the pumping system.
The supplied specifications indicate that the machine can handle smaller refractory installations at approximately 2–3 tons per hour, while providing a maximum stated output of 25 tons per hour for larger applications.
High-Pressure Swing Tube Pump
The MX-20CM incorporates a 4" x 36" ultra-high-pressure swing tube piston pump. The pump is designed for demanding refractory pump-cast and shotcrete applications.
Its piston face pressure is rated at 2,200 PSI. Oversized differential cylinders help provide high discharge pressure while operating at comparatively lower hydraulic pressure.
Pump Specifications
Pump: 4" x 36" ultra-high-pressure swing tube pump
Output: 0–25 tons per hour
Piston face pressure: 2,200 PSI
Receiving hopper capacity: 1,500 lb.
Hydraulic agitator: Included
Two-Stage Mixing for Castable Materials
Material preparation is a critical part of castable refractory installation. The MX-20CM's high-shear continuous mixer is designed to hydrate and mix material continuously before it reaches the pumping stage.
The machine provides a 3,000-lb. dry hopper capacity, while the secondary mixer in the receiving hopper provides additional material conditioning before pumping.
This integrated approach can help maintain a continuous material flow during refractory installation projects.

Power Options
The MX-20CM can be supplied with different power configurations to suit project requirements:
99 HP John Deere water-cooled diesel
102 HP Deutz water-cooled diesel
Dual electric motors
The choice between diesel and electric power can be based on jobsite conditions, available infrastructure, and mobility requirements.
Easier Cleaning and Maintenance
Refractory installation equipment must be accessible for routine cleaning and maintenance. The MX-20CM features a swing-out receiving hopper, providing easier access to the swing tube section.
The supplied product information also states that dust generated while charging the continuous mixer is substantially reduced and that mixer cleanup is quicker with very little waste.
These features can be valuable for contractors completing repeated castable installation work where equipment turnaround is important.
Available Options
The MX-20CM can also be configured with several optional accessories:
2,000 PSI hydraulic pressure washer
Vogel automatic lubrication system
Mounted spare tire
Pendant remote
Skid mounting with forklift tubing
Castable Installation Applications
The MX-20CM's combination of continuous mixing and high-pressure pumping makes it suitable for refractory placement projects where castable material must be prepared and delivered consistently.
Its capacity range allows the same machine concept to support smaller installations as well as larger projects requiring significantly higher production rates.
Before selecting equipment, operators should verify that the specific refractory castable formulation and installation method are compatible with the machine and pumping system.
