Powder locks for safe bulk material handling
Ensure containment and prevent contamination while processing sensitive bulk materials with this versatile solution designed to safely manage powders and granules.

Ensures Containment and Safe Transfer of Materials
Volkmann Powder Locks are engineered to ensure the secure and efficient transfer of powders and bulk materials, targeting industries that require strict containment, such as pharmaceutical, chemical, and food processing. These powder locks are designed to eliminate contamination by incorporating a purging feature that allows for the use of inert gases like Nitrogen, preventing unwanted atmospheric interactions during material transfer. A key advantage is their seamless integration with Volkmann’s VS and PPC series vacuum conveyors, creating a compact system suitable for processes involving buffering, separation, and filtration.
These powder locks can handle various operations, whether in continuous or manual mode, and are compatible with hazardous materials due to their pressure shock-resistant configurations up to 10 bar. Volkmann also offers options that are pressure-resistant to 6 bar, making them versatile for environments with overpressure requirements. Ideal for manufacturers of active pharmaceutical ingredients, dietary supplements, chemical compounds, and food products, these locks ensure safe material transfer and containment, maintaining the integrity of active and sensitive substances. Compliance with industry standards and customizable features provide tailored solutions for client-specific needs, ensuring streamlined integration into existing production lines.
