Core Technology & Working Principle
High-speed agitation in standard tanks naturally draws air into viscous liquids, creating micro-bubbles and causing skinning or oxidation. The PVM series keeps the whole dispersion cycle inside a hermetically sealed vessel under deep vacuum, so entrapped air pockets expand and burst immediately while the serrated impeller keeps shearing agglomerates apart.
▲ High Vacuum Bubble-Free Processing
Maintains hermetic vacuum sealing (≤ -0.09 MPa) during high-shear agitation, eliminating pinholes, micro-voids and foam in finished coatings, inks, adhesives and sealants.
▲ Volatile Solvent Containment
The hermetically sealed tank cover prevents VOC solvent evaporation, reducing material loss and maintaining a clean, compliant workshop environment.
▲ Heavy-Duty Hydraulic Lifting
Precision electric-hydraulic lift column delivers smooth, vibration-free elevation of the dispersing head for rapid tank exchange and easy washdowns, with temperature and vacuum pressure feedback sensors plus safety limit interlocks.

Our Manufacturing Advantages
🏢 Direct Source Factory
Shanghai Polyc Technology Co., Ltd. is not an engineering broker. We forge the heavy-duty cast frames and precision-machine the dispersing shafts from raw materials at our 9,000 m² Wuxi facility — hydraulic column machining, dynamic shaft balancing and vacuum cover sealing are all handled in-house, so you buy at authentic factory-direct pricing.
✈️ 30–45 Days Fast Delivery
Standard models ship in 30–45 days from confirmed drawings, thanks to our integrated vertical in-house production lines.
🛡️ Strict Quality Control
Each vacuum vessel seal, hydraulic column and drive assembly is inspected and test-run at the factory before packing and dispatch.
🔧 3-Year Global Warranty & Customization
We customize the PVM series — from vacuum pump capacity selection to PTFE wall scraper integration — to match your exact liquid viscosity. Every unit is backed by a 3-Year Global Warranty on main structures and motors, supported by rapid spare parts dispatch.
Target Application Spectrum
Vacuum de-aeration pays off wherever bubbles, solvent loss or surface oxidation ruin the finish — from high-grade coatings to cosmetic emulsions:
Industrial Coatings
Cosmetic Creams
Organic Dyes & Colorants
Adhesives & Glues
