High-speed disperser with vacuum system for defoaming. Capacity: 50-10,000 L.
The POLYC PVM Vacuum Dispersing Machine is a high-speed disperser built around a sealed, vacuum-rated vessel. It combines high-shear dispersion and vacuum deaeration in a single unit, so coatings, adhesives, sealants and electronic slurries are mixed and deaerated without entrained air. A variable-frequency drive controls tip speed, a hydraulic lift positions the dispersing head for vessel changeover, and an optional jacket keeps temperature-sensitive batches stable.

Request a QuotationApplication Scenarios: Deaerated Dispersion and Vacuum Processing
Where entrained air or solvent vapour has to be removed during dispersion, the PVM is specified simply as a vacuum disperser: the batch is dispersed and deaerated in one closed vessel, which shortens the downstream vacuum stage and improves density consistency in sealants, potting compounds and paste products.
Description
How it works
The POLYC PVM Vacuum Dispersing Machine is built for dispersing, deaerating, emulsifying and mixing raw materials across a wide viscosity range. A high-speed dispersing impeller generates strong shear that wets out powders, breaks agglomerates and shortens dispersion time.
An integrated vacuum system pulls entrained air out of the batch while the vessel lid and shaft seals stay rated for low-pressure operation. This closed design reduces solvent volatilization and material waste, and gives stable, bubble-free results for coatings, adhesives, sealants and electronic slurries.
A hydraulic lift raises the dispersing head for fast vessel changeover and cleaning, and automatic temperature and pressure feedback supports safe, repeatable operation. Explosion-proof motor and control options are available for solvent-based processes.

Equipment Guidance
Frequently Asked Questions
What is a vacuum dispersing machine?
A vacuum dispersing machine is a high-speed disperser built around a sealed, vacuum-rated vessel. It wets and disperses powders under high shear while a vacuum system removes entrained air, so adhesives, coatings, sealants and electronic slurries are mixed and deaerated in one step.
How does vacuum deaeration improve dispersion quality?
Trapped air causes bubbles, pinholes and uneven surfaces in coatings, potting compounds and electrode slurries. Removing it under 1-30 mbar vacuum gives a dense, bubble-free product with better dielectric, filling and film properties.
What capacity and viscosity range does the PVM vacuum disperser cover?
The PVM series handles working capacities from 50 to 3,000 L with motor power from 7.5 to 75 kW, and processes viscosities up to approximately 100,000 cP when fitted with the right agitator.
Vacuum disperser vs standard high-speed disperser - when should I choose vacuum?
Choose vacuum when entrained air degrades your product: bubble-free adhesives and sealants, potting compounds, creams, gels and electrode slurries. For general coatings, inks and paints without strict degassing needs, a standard high-speed disperser is usually enough.
What vacuum level can the PVM reach?
Depending on configuration, the PVM reaches approximately 1-30 mbar, which is sufficient for most deaeration and defoaming duties in adhesive, electronic and coating production.
Can the vacuum disperser handle temperature-sensitive batches?
Yes. The vessel is jacketed for heating and cooling, and a variable-frequency drive controls tip speed, so temperature-sensitive formulations stay within a stable processing window.
Is the vacuum disperser available with explosion-proof controls?
Yes. Explosion-proof motors, electrical controls and safety configurations are available when required by your solvent, plant classification or local regulations.
How do I select the right vacuum disperser configuration?
Start from batch volume, viscosity, powder loading, required vacuum level and deaeration target, then match shaft power, blade geometry, vessel cover, seal arrangement and cooling duty. POLYC engineers confirm solvent classification and explosion-protection needs before manufacture.
