The WM90P Whiteman Polyethylene-Drum Plaster/Mortar Mixer is a premier choice for contractors and rental professionals who need maximum mixing efficiency, quick cleanout, and long-lasting durability in the harshest jobsite conditions. Multiquip’s design delivers impressive capacity, outstanding reliability, and minimal maintenance—raising the bar for heavy-duty plaster, mortar, and grout mixing in commercial, industrial, and large residential projects.

Product Overview

The WM90P is part of Multiquip’s industry-proven Whiteman mixer line. Its standout feature is the EasyClean 9-cubic-foot polyethylene drum, engineered to resist build-up, corrosion, and impact damage. Unlike traditional steel drums, the poly drum makes clean-up after sticky mortar, stucco, or colored batches simple and fast—with just a few mallet taps, residual material drops out, slashing maintenance time and lowering labor costs.

Supporting up to 2.5–3.5 bags of dry mix per batch (248 liters), the drum is paired with high-strength cast iron paddle arms with rubber wipers, ensuring smooth, lump-free mixes every time. The entire unit rides on a rugged, powder-coated steel frame with a heavy-duty axle, large tires for smooth towing, and forklift pockets for safer, speedier mobility on and off the jobsite.

Engine Variants and Options

A key advantage of the WM90P is its broad range of power choices, letting crews match the mixer to their fuel preference, emissions requirements, or field needs:

• WM90PE: 3 HP Electric Motor (230V, single-phase); preferred for indoor, “green building,” or low-noise projects.

• WM90PH8: Honda GX-240, 7.9 HP Gasoline Engine; industry gold standard for reliability, cold starts, and field maintenance across North America.

• WM90PLF: 9 HP MPower Engine; offers heavy-duty power and excellent performance for rentals and high-output applications.

All models feature manual dump, V-belt drive, and OSHA-compliant welded safety grates with integrated bag cutters for quick, clean loading and operator protection.

Technical Specifications

Core Performance & Durability Benefits

• EasyClean Advantage: Poly drum eliminates rust, reduces buildup, and significantly cuts down cleanout time—contractors and rental clients routinely cite this as the “biggest productivity and profit secret” for large-batch jobs.

• Superior Mix Quality: Aggressive paddle geometry and precise speed ensure fast, thorough blending for all mortars, plasters, grouts, and specialty mixes.

• Maintenance Savings: Impact- and acid-resistant poly lasts longer than steel in corrosive or color-intensive sites; V-belt drive is smooth, quiet, and easy to service.

• Maximized Jobsite Mobility: Wide tires, removable Schedule 80 steel tongue, and standard forklift pockets allow for safe towing and effortless placement.

• Operator & Site Safety: Grate with bag breaker, positive drum lock, and wide dump chute speed work and reduce spillage, minimizing physical strain and site mess.

Applications

• Block & Brick Masonry: Meets high-volume needs for CMU, brick veneer, or paver jobs.

• Stucco, EIFS, & Plastering: Perfect batches for spreaders, applicators, and finish teams needing a constant supply of smooth material.

• Pavement & Tile Contractors: Handles thick and thin-bed mixes, sand/cement screed, commercial pools, and multi-surface paving.

• Rental Fleets: Proven for low downtime, long lifetime, and easy owner/operator maintenance.

Industry Feedback & User Reviews

• “Fastest Clean-Up We’ve Seen”: Experienced crews rave about saving “hours per week” compared to steel drum models—especially on stickier or colored mixes.

• “Runs Hard, Stays True”: Heavy-duty frames and paddle arms stand up to abusive, around-the-clock use.

• Rental Favorite: High ROI for fleet owners and repeat contractors, with less downtime for stuck drums or premature drum replacement.

Maintenance & Best Practices

• For cleanout, tap the drum’s exterior with a non-marring mallet; residue releases quickly, even after high-stick batches.

• Inspect paddles and wipers regularly; replace blades as needed for best mix consistency.

• Check belt tension, lube bearings per schedule, and follow engine or motor manufacturer service guidance.

• Engage safety lock and keep drum grate in place during operation.
