Mercury DC-19-2000 Ultra D.C. High-Speed Burnisher – 19", 2000 RPM
Mercury DC-19-2000 Ultra D.C. Burnisher – 19" High-Speed Floor Polisher at 2000 RPM
The DC-19-2000 is Mercury's 19" high-speed burnisher running at 2000 RPM — the same motor and speed as the 20" and 21" DC models in this series, in a footprint that navigates tighter spaces more easily. The 1.5 HP D/C rectified motor eliminates the burnout and startup torque issues common in AC-motor burnishers. The front caster assembly with flexible pad holder maintains even pad pressure across the full 19" width, and the polished aluminum chassis adds machine weight that seats the pad firmly against the floor without operator effort.
DC-19-2000 Motor, Chassis, and Pad Pressure System
- Motor: 1.5 HP D/C rectified, 15 Amp — eliminates low-voltage burnout and startup torque
- Speed: 2000 RPM — high-speed burnishing for gloss restoration on VCT, sealed concrete, and linoleum
- Apron size: 19" with full-wrap non-marking bumpers
- Pad pressure: front caster with flexible pad holder and threaded pad-centering device
- Chassis: polished aluminum, 84 lbs. machine weight
- Operating wheels: 6" non-marking; transport wheels: 4" non-marking
- Handle: adjustable 48" — non-conductive dual triggers, safety interlock switch
- Power cord: 50-ft. 14/3-gauge safety cord, handle-base connection
Where the DC-19-2000 Gets Used
The 19" apron is the most common burnisher size in commercial janitorial use because it fits through standard doorways (36" minimum clear width) without the clearance adjustments the 20" and 21" machines occasionally require. Grocery store service corridors, office hallways, school gymnasiums, and hospital corridors are typical applications. At 2000 RPM on VCT, it can restore a wet-look gloss finish in a single burnishing pass after a spray-buff application, cutting total floor maintenance time compared to multi-pass operations at lower RPM.
Pro Application Details for the DC-19-2000
At 2000 RPM, pad selection is critical: use white, tan, or natural fiber burnishing pads. Aggressive pads (black or green) at this speed will remove finish, not polish it. The front caster assembly does the pad pressure work — the operator guides the machine without pushing down on the handle, which would lift the front caster and create uneven pad contact. The interlock switch stops the machine the moment the handle is released, which is important for operator safety in active commercial environments. All DC-series Mercury burnishers in 19", 20", and 21" share the same motor; choose the size based on the primary spaces the machine will work in.
