Multiquip 506307 Poly Drum WM-900P EM-900P

The Multiquip 506307 Poly Drum WM-900P EM-900P is a genuine OEM replacement drum designed for the EM900 and WM900 series plaster and mortar mixers. As a direct factory replacement, 506307 delivers an exact fit to the original drum position, requiring no adaptation to mounting hardware or drive components. DHS Equipment stocks this part as an authorized Multiquip OEM component, so you can order with confidence knowing you are receiving the correct part for your machine.

Key Features

• OEM-Grade Poly Construction — Manufactured to Multiquip's original material specification, this polyurethane drum resists mortar buildup and chemical attack that would degrade a lower-grade drum over time.
• Direct Drop-In Replacement — Engineered to the same mounting geometry as the original, 506307 seats directly onto EM900 and WM900 mixer frames without reworking the drive ring or support cradle.
• Confirmed Fitment for EM900 and WM900 — Verified compatible with Essick EM900 and Whiteman WM900 plaster and mortar mixer models, covering both product lines in this mixer family.
• Maintains Mix Integrity — A sound drum keeps mortar and plaster fully contained and properly tumbled; a cracked or warped drum causes uneven mixing, material loss, and increased cleanup time on the job.
• Genuine OEM Part — Sourced directly from Multiquip, 506307 meets the same dimensional and structural standards as the drum that shipped with the machine at the time of manufacture.

The drum is the primary mixing chamber on a plaster and mortar mixer — it holds the material, rotates to tumble and blend the mix, and discharges the finished product through the drum opening. On polyurethane-drum models like the EM900 and WM900, the poly construction prevents mortar from bonding to the interior surface and makes cleanup faster between batches. When a drum cracks, warps, or develops a damaged lip, it compromises the seal against the discharge chute, causes material to leak mid-cycle, and can place uneven load on the drive ring and motor. Replacing a worn drum promptly with a correct OEM unit like the Multiquip 506307 restores proper mixing action and protects the surrounding drivetrain components from accelerated wear.
