PVDF (polyvinylidene fluoride) powder is a high-performance engineering thermoplastic widely used in chemical processing, semiconductor manufacturing, water treatment, and lithium battery production. Because PVDF powder is abrasive, electrostatic, and easily contaminated, handling it requires a purpose-built pneumatic conveying system. Our custom solutions offer safe, gentle, and dust-free transfer from storage silos, bulk bags, or drums to process equipment.

We design both dense phase and dilute phase pneumatic conveying systems. Dense phase conveying uses low gas velocity and high pressure to move PVDF powder as a plug, which minimizes particle breakage and pipe wear. This is ideal for fragile powders and long distances. Dilute phase conveying suspends the powder in a high-velocity air stream and suits shorter distances and simpler layouts. Our engineers evaluate each process to choose the most efficient and economical solution.

Key system components include stainless steel blow pots or vacuum receivers, precision rotary airlock valves, roots blowers or vacuum pumps, reverse-jet filter housings, pneumatic diverters, level sensors, and a fully integrated PLC control panel. All contact parts can be manufactured from 304 or 316L stainless steel with smooth, easy-to-clean surfaces. The pipeline uses correctly sized bends and smooth interior walls to avoid material buildup. Additional options such as nitrogen purging, moisture removal, and automatic cleaning cycles are available.

Our PVDF powder conveying systems deliver consistent flow, low energy consumption, reduced material degradation, and completely sealed operation. The PLC automatically regulates conveying pressure, gas velocity, and cycle timing to prevent plugging and ensure stable transfer. Real-time sensors provide continuous feedback, while remote monitoring enables quick adjustments. Anti-wear elbows and rugged construction significantly extend equipment life, lower maintenance costs, and reduce the total cost of ownership.

Electrostatic hazards are a major concern in PVDF powder conveying. We integrate grounding electrodes and static-dissipative components throughout the system to prevent charge accumulation. For explosive environments, options include inert gas blanketing, oxygen analyzers, pressure relief panels, and explosion suppression systems. Our anti-wear elbows with replaceable inserts extend pipeline life and safety. These features ensure reliable operation in classified hazardous areas.

Applications include PVDF resin production, membrane filtration, coating powder transfer, lithium battery binder mixing, and chemical additive feeding. We support single-point transfer, multi-silo distribution, batch weighing, and continuous feeding configurations. Our complete project services include site surveys, material characterization, process design, 3D layout simulation, fabrication, installation, commissioning, and operator training. Each system is customized to your plant layout and production goals.

All systems are manufactured under ISO 9001 quality standards and thoroughly tested before shipment. We deliver full documentation including mechanical drawings, P&ID diagrams, datasheets, and operation manuals. Our after-sales support covers remote diagnostics, spare parts supply, and preventive maintenance programs.
