Efficient refractory placement depends on reliable mixing, consistent material preparation, and sufficient pumping pressure. The Blastcrete MX-20CM Mixer/Pump brings these functions together in one machine, combining a high-shear continuous mixer with a 4-inch high-pressure swing tube piston pump.
With a stated maximum output of 25 tons per hour, the MX-20CM is designed to support both smaller refractory projects and high-volume castable installation applications.
High Pressure Refractory Castable Pump
The MX-20CM can serve as a high pressure refractory castable pump for applications requiring controlled delivery of refractory material. Its 4" x 36" swing tube piston pump provides a stated 2,200 PSI piston face pressure.
The pumping system uses oversized differential cylinders, allowing high discharge pressure while requiring comparatively lower hydraulic pressure to operate the pump.
This combination is intended for demanding refractory pump-cast and shotcrete applications where dependable material movement is important.
Two-Stage Mixing System
The MX-20CM uses a compact two-stage mixing arrangement. The primary mixer is a high-shear continuous mixer where material is hydrated. A secondary medium-shear mixer is positioned in the receiving hopper before the material enters the pump.
This configuration is designed to maintain a continuous material preparation and pumping process.
The mixer has a stated output of up to 25 tons per hour, matching the maximum stated pump capacity.
High-Pressure Pump Specifications
The MX-20CM's pump system includes:
4" x 36" ultra-high-pressure swing tube pump
Pump output: 0–25 tons/hour
Piston face pressure: 2,200 PSI
1,500-lb. receiving hopper
Hydraulic agitator in receiving hopper
Swing-out hopper for easier access to the swing tube section
The swing-out receiving hopper can simplify cleaning and routine maintenance by providing easier access to the pumping components.
Designed for Refractory Castable Applications
Castable refractory projects can require equipment capable of handling continuous material flow while maintaining efficient mixing and pumping. The MX-20CM's integrated mixer/pump design reduces the need for separate material preparation and pumping equipment.
Its 3,000-lb. dry hopper provides substantial material capacity, while the continuous mixer is designed for high-volume operation.
For smaller installations, the machine can also be operated at lower production rates, with the supplied information indicating applications of approximately 2–3 tons per hour.

102 HP Deutz Diesel
The machine can alternatively be equipped with a 102 HP water-cooled Deutz diesel engine.
Dual Electric Motors
For facilities with suitable electrical infrastructure, a dual-electric-motor configuration is also available.
Operational and Maintenance Advantages
The MX-20CM's two-stage mixing arrangement is designed to reduce dust generated during continuous mixer charging. The supplied product information also states that cleanup of the continuous mixer is quicker and generates very little waste.
The swing-out receiving hopper provides access to the swing tube section for cleaning and maintenance. These features can be particularly useful when the equipment is used repeatedly across refractory installation projects.
Available Options
The MX-20CM can be configured with additional equipment, including:
2,000 PSI hydraulic pressure washer
Vogel automatic lubrication system
Mounted spare tire
Pendant remote
Skid mounting with forklift tubing
These options allow the equipment to be configured according to specific jobsite and operating requirements.
MX-20CM for High-Volume Refractory Work
A major advantage of the MX-20CM is its stated 25-ton-per-hour maximum mixer and pump capacity. This gives contractors the ability to use the same machine for lower-output refractory work and larger installations.
The combination of continuous mixing and high-pressure pumping can help streamline material handling where steady production is required.
The machine's stated towing weight of 7,500 pounds also makes it suitable for projects where equipment mobility is important.
