The EM90S Essick Steel-Drum Plaster/Mortar Mixer stands as Multiquip’s flagship 9-cubic-foot steel-drum mixer, prized throughout the construction and masonry industry for its rugged engineering, advanced seal system, and exceptional batch consistency. Built to satisfy contractors, masonry crews, and rental fleets who demand continuous, trouble-free mixing for mortar, stucco, grout, and plaster, the EM90S is offered with a variety of top-tier engine configurations to meet any jobsite or workflow requirement.

Product Overview & All Engine Variants

The EM90S Essick mixer is specifically engineered for high-capacity, heavy-duty mixing—capable of holding 9 cubic feet (2.5–3.5 bags) per batch. This volume makes it ideal for major commercial masonry, extensive stucco projects, and demanding rental applications. The mixer’s premium 10-gauge steel drum, precision-cast iron paddle arms with rubber blades, and maintenance-free, spring-loaded shaft seals ensure smooth operation and long-term reliability.

Available engine/power variants include:

• EM90SE – 3 HP 230V Single Phase Baldor Electric: For emissions-free, quiet, indoor work and regulated jobsites.

• EM90SH8 – 7.9/8 HP Honda GX240 Gasoline: The go-to for contractors needing maximum field reliability and fast cold starts.

• EM90SLF – 9 HP MPower Gasoline: Delivers heavy-duty torque, robust performance, and added value for high-vibration and rental environments.

Every EM90S is engineered with a robust V-belt drive, 14-gauge engine cover, high-strength tubular frame with powder coating, large manual dump handle, heavy-duty axle, and standard highway-ready towing tongue.

Technical Specifications

Seal System, Engineering & Long-Term Durability

• Innovative Shaft Seal System: Spring-loaded, graphite-impregnated seals are self-adjusting and totally maintenance-free; require no greasing and protect bearings from water and abrasive slurry for the mixer’s entire lifespan.

• Cast Bull Gear & Pinion: Precision-machined from high-strength steel for years of service, even with heavy loads or stiff mixes.

• Engineered Silence & Low Vibration: Engine mounted directly to the base for less vibration and easier oil checks.

• Safety & Ergonomics: Power-off drum locks, wide chute, OSHA grate, and balanced dump design minimize accidents, downtime, and cleanup.

Batch Consistency & Performance

• Uniform, Lump-Free Mixing: Optimized paddle and drum shape ensure superior blend of mortar or plaster in every load, maximizing jobsite quality and reducing “dead batch” risk.

• Fast Loading & Mixing: Safety grate with bag cutter speeds up dry material addition and enhances operator protection, while the aggressive paddle arm design thoroughly mixes even stiffest products quickly.

• Ideal for All Mixes: Excels at stiff mortar, fine grout, higher-slump plaster, and demanding lime or sand/cement ratios; reliable for stone, brick, block, or stucco crews.

Engine Options: Advantages

• Electric (EM90SE): Quiet, fume-free, excellent for schools, hospitals, basement jobs, and green building compliance.

• Honda GX240 Gasoline (EM90SH8): Field-proven, fast starting, universally serviceable, with unmatched day-to-day reliability even in harsh climates and high-use scenarios.

• MPower 9HP Gasoline (EM90SLF): Heaviest-duty, ideal for high-cycle commercial jobs and busy rental fleets where long lifespan and easy parts access are critical.

Applications

• Large-Scale Masonry Work: Perfect for block, brick, and veneer installations needing frequent, consistent, and large mortar batches.

• Plaster & Stucco Crews: Keeps plasterers and masons supplied on high-volume, multi-crew exteriors.

• Tile Bed & Hardscape: Mixes sand/cement beds and grout for commercial/industrial tiling, pools, and pavers.

• Rental Fleets: Uniform design, easy maintenance seals, and service simplicity make EM90S a star in the rental market.

Industry Reviews & User Impressions

• “Professional’s Choice”: Users highlight long service intervals, excellent seals that require “no attention or greasing,” and “bulletproof” reliability across brutal rental or construction schedules.

• “Easy to Clean & Move”: Operators love the wide drum opening, quick dump, removable tongue, and forklift pockets.

• “Outstanding ROI”: Fleet managers and contractors report low lifetime cost, strong resale, and high utilization rates compared to lighter, consumer options.

Maintenance Best Practices

• Clean drum & paddles daily, especially after colored or sticky mixes.

• Visually inspect the shaft seephole regularly—seal replacement is rare, but prompt action prevents bearing issues.

• Lubricate belt and check tension weekly.

• Follow all manufacturer engine/electric motor service schedules for maximum uptime.
