Dispersers
POLYC PDM single shaft high speed disperser, also called a dissolver, is a general-purpose wet dispersing and mixing machine for paint, coating, ink and pigment. It uses a sawtooth disc driven by a VFD-controlled motor to shear and wet out liquid-solid batches, with hydraulic lifting for fast vessel change and cleaning. Sizes cover 50 to 5000 L.

| Material Type | Viscosity Range | Typical Speed | Batch Size |
|---|---|---|---|
| Low-viscosity coatings | < 5,000 cP | 1,500-3,000 rpm | 10-1,000 L |
| Medium-viscosity paste | 5,000-50,000 cP | 1,000-1,500 rpm | 50-500 L |
| High-viscosity adhesive | > 50,000 cP | 500-1,000 rpm | 50-500 L |
Typical reference values only. Actual results depend on formulation, bead material, and process conditions. Material testing is recommended before final selection.
Equipment Benefits
Fast solid dissolution: the high-speed dispersing disc rapidly wets and dissolves powder into the liquid phase, handling large-capacity batches in one vessel.
From lab to production: available from small lab units up to large production machines configured to your batch volume and viscosity.
Safe lift operation: limit switches prevent the shaft from starting during lift up/down or without a vessel, protecting the operator.
Explosion-proof option: explosion-proof motors, controls and limit switches are available for solvent-based and hazardous-area installations.

Equipment Guidance
A high-speed disperser rapidly wets, mixes, and disperses powders into liquids. It is widely used for coatings, inks, adhesives, pigments, resins, and chemical products.
Selection depends on vessel size, viscosity, powder loading, and target dispersion quality. POLYC MACHINE engineers match motor power, impeller size, and speed control to your process.
Yes. We offer high-torque dispersers, vacuum dispersers, and double-shaft configurations for high-viscosity pastes, adhesives, sealants, and concentrated slurries.
POLYC MACHINE supplies laboratory, pilot, and production dispersers with vessel sizes configured to your batch volume. Lifting frames and closed vessels are also available.
Yes. Vacuum dispersing systems reduce air entrainment and help remove bubbles from coatings, adhesives, sealants, and electronic slurries.
