The PRO12 MQ Essick PRO12 Series Stationary Mixer by Multiquip is a premium, high-capacity stationary mortar and plaster mixer designed for professional contractors, precast plants, and large masonry crews who demand maximum output, ergonomic operation, and unmatched durability. Engineered to deliver exceptional productivity when paired with on-site silo dispensing systems or for mixing stiff, high-aggregate mixes, the PRO12 Series stands out as one of the toughest, most efficient stationary mixers on the market.

Product Overview

The PRO12 Series is purpose-built for withstanding day-after-day use on large-scale jobsites and in plant environments. With a formidable 12 cubic foot (340 L) batch capacity, it supports the mixing of 3–4 bags per batch, easily accommodating the needs of commercial contractors looking to maximize throughput and reduce batching times. Its robust hydraulic drive system ensures seamless, powerful mixing action, capable of powering through even the stiffest mix designs and handling up to 1-inch aggregate with no drop-off in performance.

A unique over-center hydraulic dump design allows for effortless material discharge with minimal operator fatigue, while the highly adjustable discharge height (24–42.5") ensures compatibility with a variety of containers, tubs, or conveyors. The extra-thick 1/4" steel drum wrap with 3/8" ends and a compact, travel-friendly design means the PRO12 is as durable as it is practical—easily fitting in a standard pickup bed, rolling through jobsite gates, or nestling near the base of scaffolding or silo towers.

Key Features and Core Benefits

• Massive 12 Cu. Ft. Drum: Provides batch capacity for high-output projects—ideal for large crews, plant environments, or continuous mixing via silo feeds.

• Extra Thick Drum Construction: 1/4" steel wrap with 3/8" drum ends delivers superior resistance to abrasion, denting, and long-term wear.

• Hydraulic Drive Mix and Dump: Enables consistent, powerful mixing of stiff, low-slump or high-aggregate loads. Hydraulic dump action reduces manual labor and makes unloading faster and safer.

• Adjustable Discharge Height: Easily discharge into tubs, carts, or conveyors, helping crews adapt to workflow and cut unnecessary lifting and spills. Adjustable from 24" to 42.5" high.

• Compact, Maneuverable Footprint: Engineered to fit in a truck bed and access hard-to-reach job areas; built-in swing away stabilizers (130°) adapt to uneven ground.

• Long Runtime and Efficient Power: 5-gallon fuel tank supports up to 8 hours of mixing with gas engine variants; electric drive versions offer simple plug-and-play operation in plants.

• Spill Plate: Minimizes waste and costly rework by directing all material into the tub or container.

• Universal Forklift Pockets: Forklift access from all four sides allows quick, safe placement or loading.

• Greaseable Paddle Shaft Seal: Increases lifetime and resists leaks, even with fine or sticky mixes.

• Drive/Dump Controls Above Engine Cowling: Keeps controls away from dust/mud and within easy reach for operator comfort and safety.

Technical Specifications

Applications

• Silo and Plant Batching: Designed for integration with on-site silos and bulk materials dispensing systems, making it the stationary mixer of choice for major commercial jobs or masonry plants.

• Large Commercial Masonry: Supports block, brick, and precast panel production; reduces waiting for mixes, maximizing man-hour efficiency.

• Stucco & Render Operations: Capable of mixing thick, colored, or fiber-reinforced finishes needed by exterior envelope specialists.

• Precast/Utilities: Handles grout, wet-set mixes, or sand/aggregate batches for forms, curbs, or utility vaults.

Contractor Reviews & Real-World Benefits

• Superior Torque for Tough Mixes: Contractors report that the PRO12 outpaces competitors with “the most torque on the shaft of anything on the market,” resulting in faster, smoother blends of even the heaviest mixes.

• Low Fatigue, High Output: Waist-level loading and high dump points mean less bending and lifting, reducing back strain and slashes cleanup/pour times.

• Rugged, Lifetime Drum: The extra-thick drum wrap and three-eighths ends ensure “years and years of trouble-free use,” ideal for rental fleets, busy plants, or multiyear builds.

• Efficient on the Jobsite: Field feedback notes that fitting the mixer in pickup beds and through scaffold clearances saves crucial time and optimizes workflow—a rare find at this size and power.

• Long Runs, Minimal Fuel Stops: With up to 10 hours from a single tank (gas), and electric models for continuous plant batching, downtime is drastically reduced.

Best Practices & Maintenance

• Grease paddle shaft seal each week for maximum drum life.

• Check and tighten hydraulic and mechanical fasteners monthly, or after every heavy mix run.

• Inspect and replace spill plate and paddle blades yearly; drum cleanout after colored or acid mixes is critical.

• Always align discharge height to containers for safe, efficient dumping.

Frequently Asked Questions
