Mayco LS450 45 yd/hr, Hatz 4H50 74.5HP Turbo Diesel - Best to call for pricing and availability.

The "Work Horse" For Most Hard-Rock Applications

Filling a niche that has been neglected, the Mayco LS450 Concrete Pump has the versatility to efficiently place 2"-line mixes (3/8" pea gravel, masonry grout, shotcrete), structural concrete containing up to 1.5" aggregate, as well as everything in-between. Equipped with 6" diameter concrete cylinders and utilizing a 36" stroke ensures that the Mayco LS450 will smoothly pump even low slump concrete mix designs.

The Mayco Concrete Pump for sale has a balanced independent hydraulic circuit that guarantees a smooth changeover throughout, reducing to a minimum the tiring pump surge and premature wear on placing components. The 'true reverse' feature allows for immediate reversal of the pump stroke at any point allowing you to avoid troublesome line blockages in both a timely and safe manner.

The Mayco Concrete Pump has a powerful Hatz 74.5 diesel engine helps put meaningful working force behind the LS450's 1100psi concrete delivery pressure so that you get true performance at distances rarely achieved by other concrete pumps in this class. The Mayco LS450 Concrete Pump is the true value choice for contractors who need performance without breaking the bank.

The Mayco LS450 Concrete Pump is a high-output, heavy-duty hydraulic swing tube trailer pump engineered for versatile performance across a wide range of concrete applications. Trusted by contractors on demanding job sites, this powerhouse blends robust pumping capabilities, advanced controls, and operator-friendly design to ensure maximum productivity and reliability for both commercial and residential projects.

Overview of the Mayco LS450 Concrete Pump

Branded as the “work horse” for hard-rock applications, the Mayco LS450 is designed to tackle challenging jobs—whether placing 2" line mixes, shotcrete, masonry grout, or structural concrete with aggregates up to 1.5" in diameter. The pump’s heavy-duty 6" diameter concrete cylinders and 36" stroke empower it to smoothly deliver even low-slump concrete mixes, setting it apart in its class for both power and flexibility.

Key Features & Benefits

• Outstanding Versatility: The LS450 pump is compatible with 3/8" pea gravel, many grout types, shotcrete, structural mixes with up to 1.5" aggregate, and more—making it an all-in-one solution for footings, slabs, block fill, basements, compaction grouting, and shotcrete applications.

• Massive Output: Variable volume output adjustable from 0 to 45 cubic yards (34.4 cubic meters) per hour, controlled directly from the innovative digital control panel (DCP).

• Powerful Diesel Engine: Equipped with a Tier 4 Final Hatz 4H50 turbo diesel engine, delivering 74.5 HP (55.5 kW) and industry-leading reliability even on the toughest jobs.

• High Output Pressure: With a concrete piston face pressure of 1,100 PSI (76 bar), the LS450 is capable of pumping concrete up to 300 feet vertically and 1,000 feet horizontally (depending on mix and line size).

• Innovative Hydraulic System: Independent hydraulic circuit ensures a smooth, low-pulse changeover at the end of each stroke, reducing component wear and minimizing surge for consistently steady concrete flows.

• True Reverse System: This safety-focused function offers instant reversal of the pump stroke at any point, which helps quickly clear line blockages—saving time and material while boosting safety.

• Advanced DCP (Digital Control Panel): A solid-state, electronic control box offers full diagnostic and performance monitoring with simple, intuitive operation.

• Hopper Remixer/Agitator: Keeps mixes uniform and prevents premature set, especially important for low-slump and specialty aggregates.

• Durable Wear Components: Hard-faced, replaceable parts ensure a longer operational lifespan and less downtime.

Technical Specifications

Application Range

• Shotcrete and pool construction

• Structural slabs, beams, and columns

• Masonry block fill

• Footings and foundations

• Basement and retaining wall pours

• Compaction and specialty grouting

• Large-scale commercial and industrial pours

The LS450’s power and variable output capabilities make it well-suited for everything from precision placement in tight spaces to high-output production pours.

Operator Experience & Serviceability

Operators benefit from easy-access controls and monitoring, robust safety features, and optional wireless remote functionality (range up to 500 feet), which enables hands-free control during critical job moments. The hopper agitator guarantees uniform material flow, and replaceable components like pistons and wear rings streamline maintenance.

Dump-valve and quick-cleanout systems enhance turnaround between jobs, while central greasing points and sight gauges enable daily checks and upkeep in minimal time.

Advanced Technologies

• Digital Control Panel (DCP): The diagnostics-enabled display tracks all major system parameters, service intervals, and emergency alerts, reducing risk of unexpected breakdowns in the field.

• Agitator/Hopper Vibrator: Keeps mix moving and reduces line clog risk, especially useful for stiffer or high-aggregate-content mixes.

• Hydraulic Outriggers: Optional system increases trailer stability during pumping operation, essential on uneven or sloped jobsites.

Durability & Longevity

• Hard-faced Wear Parts: Put through rigorous testing for abrasion resistance, these last longer under high-cycle and aggregate-heavy tasks.

• Painted and powder-coated frame: Provides corrosion and chip resistance for extended service life.

• Legendary Hatz diesel engine: Chosen for its long-term reliability, fuel efficiency, and quiet operation in all weather.
