Reliable pumping equipment is essential for demanding refractory and shotcrete applications where material must be mixed, transported, and placed efficiently. The Blastcrete MX-20CM combines continuous high-shear mixing with a powerful piston pumping system to provide an integrated solution for refractory placement.
Featuring a 4-inch x 36-inch swing tube piston pump, the MX-20CM is designed for rugged refractory pump-cast and shotcrete applications. Its pumping system delivers a stated 2,200 PSI piston face pressure and can achieve output of up to 25 tons per hour.
What Is a Piston Concrete Pump?
A piston concrete pump uses reciprocating pistons to move material through a delivery line. The piston action provides positive displacement, allowing the pump to handle demanding material-placement applications.
The MX-20CM uses an ultra-high-pressure swing tube piston pump specifically designed for refractory placement.
Its pump specifications include:
4" x 36" piston pump
Swing tube design
2,200 PSI piston face pressure
0–25 tons/hour output
Hydraulic receiving hopper agitator
1,500 lb receiving hopper capacity
This configuration is intended for rugged refractory pump-cast and shotcrete applications.
MX-20CM Swing Tube Pump
The swing tube pump is a key component of the MX-20CM.
A swing tube directs material from the receiving hopper into the pumping cylinders and then into the discharge line. The MX-20CM's swing tube system is designed for high-pressure material delivery.
The machine uses a:
4" x 36" Ultra High Pressure Swing Tube Pump
The manufacturer specifies a piston face pressure of 2,200 PSI and a maximum pump output of 25 tons per hour.
Two-Stage Mixing and Pumping System
The MX-20CM integrates mixing and pumping into one machine.
The material passes through two mixing stages before entering the swing tube pump.
Stage 1: High-Shear Continuous Mixer
The primary continuous mixer is designed to hydrate the material.
It provides a stated output of up to 25 tons per hour.
Stage 2: Secondary Mixer
A medium-shear secondary mixer is mounted inside the receiving hopper.
This provides additional mixing before the material enters the piston pump.
Material Flow
Dry Material → High-Shear Mixer → Secondary Mixer → Receiving Hopper → Swing Tube Pump → Placement
This integrated process is designed to provide continuous material preparation and pumping.
Piston Pump for Refractory Applications
Although the term piston concrete pump is commonly used for concrete pumping equipment, the MX-20CM is specifically designed for refractory placement.
Its high-pressure pump can be used for suitable:
Refractory pump-cast applications
Shotcrete applications
Furnace repair
Kiln maintenance
Boiler refractory work
Steel plant refractory projects
Foundry applications
Industrial furnace maintenance
Refractory lining installation
Refractory repair
Material compatibility should always be confirmed with the refractory material manufacturer and equipment specifications.
High-Pressure Swing Tube Pump Performance
The MX-20CM's pump provides a stated piston face pressure of 2,200 PSI.
Its maximum output is:
0–25 tons per hour
Actual production depends on the material being pumped and jobsite conditions, including mix design, hose length, hose diameter, pumping distance, vertical lift, and operating configuration.
Swing-Out Receiving Hopper
Maintenance accessibility is another important feature of the MX-20CM.
The machine includes a swing-out receiving hopper that provides easier access to the swing tube section.
This can simplify:
Pump cleaning
Swing tube inspection
Routine servicing
Material removal
Maintenance
Forklift tubing is also mounted to the lower hopper to assist with flat-pack removal.
High-Shear Continuous Mixing
The high-shear continuous mixer is designed to hydrate the material before pumping.
The MX-20CM's mixer has a stated output of up to 25 tons per hour, matching the maximum rated pump output.
The two-stage mixing arrangement is intended to prepare material consistently before it enters the high-pressure pumping section.
Reduced Dust and Cleanup
The MX-20CM is designed to reduce dust generated while charging the continuous mixer.
The manufacturer also states that cleanup of the continuous mixer is faster and generates very little waste.
For contractors performing repeated refractory installations, these features can help simplify equipment preparation and maintenance between projects.
MX-20CM Power Options
The machine is available with several power configurations.
Diesel Engines
99 HP John Deere water-cooled diesel
102 HP Deutz water-cooled diesel
Electric Power
Dual electric motors
The two-stage mixer and pumping system requires approximately 100 HP.
The supplied information states that fuel consumption can be reduced by 50% compared with competitive machines. Actual fuel consumption will vary according to workload, material, operating conditions, and machine configuration.
