When refractory installation projects demand reliable mixing, consistent material delivery, and high production capacity, selecting the right mixer/pump configuration is important. The Blastcrete MX-20CM Mixer/Pump combines a high-shear continuous mixer with a 4-inch high-pressure swing tube pump, providing a practical solution for both smaller refractory jobs and high-volume installations.
The MX-20CM is designed to handle production from approximately 2–3 tons per hour up to 25 tons per hour, making it suitable for demanding refractory placement applications.
MX-20CM Power Options
One advantage of the MX-20CM is its flexible power configuration. Depending on the project and operating environment, the machine can be supplied with diesel or electric power.
Diesel Powered Refractory Mixer Pump
A diesel powered refractory mixer pump can be useful for projects where equipment needs to operate independently of a permanent electrical supply. The MX-20CM is available with either a 99 HP John Deere water-cooled diesel engine or a 102 HP Deutz water-cooled diesel engine.
Its trailer configuration and approximately 7,500-pound towing weight can make transportation between job locations practical. The machine is also designed for straightforward crane lifting and servicing.
Electric Refractory Mixer Pump
For facilities with suitable electrical infrastructure, an electric refractory mixer pump configuration can provide an alternative to diesel operation. The MX-20CM is available with dual electric motors, allowing users to select an electric-powered setup where it fits their installation requirements.
Choosing diesel or electric power should depend on factors such as available utilities, mobility requirements, operating environment, and project specifications.
Two-Stage Mixing for Refractory Materials
The MX-20CM incorporates a two-stage mixing process. Its primary high-shear continuous mixer hydrates the material before it moves into a secondary medium-shear mixer located in the receiving hopper.
This arrangement is designed to provide continuous material preparation while supporting production rates of up to 25 tons per hour. The 3,000-pound dry hopper and 1,500-pound receiving hopper provide substantial material-handling capacity for demanding applications.
High-Pressure Swing Tube Pump
At the heart of the MX-20CM is a 4-inch x 36-inch ultra-high-pressure swing tube piston pump. The pump features a piston face pressure of 2,200 PSI and is designed for rugged refractory pumping and shotcrete applications.
Oversized differential cylinders allow the pump to deliver high discharge pressure while operating with comparatively lower hydraulic pressure. This design can contribute to efficient operation in high-volume refractory placement.
Key MX-20CM Features
The MX-20CM combines several features intended to simplify operation, maintenance, and material handling:
4-inch x 36-inch swing tube piston pump
2,200 PSI piston face pressure
Up to 25 tons-per-hour pump output
Up to 25 tons-per-hour mixer output
High-shear continuous mixing system
3,000-pound dry hopper capacity
1,500-pound receiving hopper with hydraulic agitator
Swing-out receiving hopper for easier cleaning and service
0–20 gallon flow meter
Solid-state electronic controls
Four-point crane pickup
Forklift tubing for flat-pack removal
CE certification
Dual 6,000-pound-capacity axles with electric brakes and lights
Why Production Capacity Matters in Refractory Installation
High-volume refractory projects can require equipment capable of maintaining consistent material preparation and pumping over extended periods. With a rated output of up to 25 tons per hour, the MX-20CM is designed to accommodate both moderate and high-production requirements.
Its compact continuous mixing system also helps reduce the handling and cleanup associated with conventional batch mixing. According to the supplied product information, the two-stage mixer and pump design requires approximately 100 HP and can reduce fuel consumption by 50% compared with competitive machines.
Maintenance and Service Advantages
Refractory equipment needs to be cleaned and serviced regularly, particularly when working with materials that can harden inside equipment. The MX-20CM's swing-out receiving hopper provides direct access to the swing tube section, helping simplify cleaning and routine maintenance.
The machine also offers options such as a 2,000 PSI hydraulic pressure washer, Vogel automatic lubrication system, pendant remote, spare tire, and skid mounting with forklift tubing.

Choosing the Right MX-20CM Power Configuration
A diesel powered refractory mixer pump may be preferable when portability and independent operation are priorities. An electric refractory mixer pump can be a strong choice for fixed or industrial locations where appropriate electrical power is readily available.
Regardless of the power configuration, the MX-20CM combines continuous high-shear mixing with a high-pressure swing tube pump to support demanding refractory placement applications.
