Vacuum Conveyors

Product catalog summary
Introduction
Volkmann GmbH, founded in 1973, is a German family-owned company specializing in vacuum technology. They offer innovative solutions for vacuum conveyors, pumps, and components, emphasizing flexibility, quick decision-making, and high-quality engineering.
Product Overview
Volkmann provides vacuum conveyors for industries such as chemical, pharmaceutical, food, and pigment sectors. These conveyors ensure dust-free, gentle material transfer, requiring minimal maintenance and offering easy installation and control.
Applications
The vacuum conveyors are suitable for transporting powders, granules, and small parts, especially in industries with high hygienic demands. They allow for regular cleaning and easy disassembly.
Technical Specifications
The conveyors handle capacities from 20 to 10,000 kg/h, with a maximum height of 35 meters and a distance of 80 meters. They operate using a vacuum pump that creates a vacuum in the separator tank for efficient material transport.
Conveying Methods
1. Flight Conveying: High air speed for large capacities, not suitable for sensitive materials.
2. Dilute Phase Conveying: Lower air speed, gentle handling, suitable for various products.
3. Plug Conveying: Low air speed, high product load, ideal for sensitive materials.
Advantages
Volkmann's conveyors offer modular design, easy dismantling, GMP suitability, superior filter technology, and custom adaptations. They are lightweight, compact, and operate quietly without heat emission.
Specifications and Design
The conveyors are made from stainless steel, resistant to cleaning agents and aggressive chemicals. They feature modular designs for easy disassembly and cleaning, with radial and tangential suction inlets affecting the conveying process.
Procedures
Choosing the appropriate suction connection is crucial. Tangential connections reduce filter load for fine powders, while radial connections suit sticky materials. Suction trials are recommended to determine the best configuration.
Standards and Certifications
All new VR and PPC series conveyors are ATEX certified for safe operation in explosive environments, designed to be electrically conductive and free of ignition sources.
Recommendations
The VR series is recommended for industries needing flexible and hygienic powder handling, while the PPC series is ideal for pharmaceutical applications due to its one-piece design and ease of cleaning. Inerting functions are available for explosive or flammable materials.
Key Features
The VR series offers a wide range of modules and configurations, while the PPC series is designed for easy disassembly and cleaning without tools. Both series provide options for integrated filters, vacuum pumps, and control systems.
Conveying and Dosing Systems
Volkmann offers systems with weighing and dosing functions, built on VR and PPC conveyors, designed for precise material handling and integration with process control systems.
Complete Solutions
Volkmann provides comprehensive solutions for powder handling, from container emptying to material supply in production processes, designed to be dust-free and operate under inert conditions.
Additional Features
Various accessories and options, such as suction lances, mounting elements, and filter systems, enhance the functionality and safety of the vacuum conveyors, customizable to fit specific operational needs.
Conclusion
Volkmann's vacuum conveyors offer reliable and safe solutions for handling hazardous and sensitive materials, focusing on customization, safety, and efficiency. The systems are supported by comprehensive documentation and qualification services to ensure compliance with industry standards.

Conditions inside the transportation line The total pressure difference in the transportation line essentially results from the quantity of the material to be conveyed in the line, its flow characteristics, the conveying height and the design of the product loading element and transportation line. The vacuum pump must be able to overcome the total pressure loss inside the conveying line and at the same time to produce the flow rate necessary for the transport of the material (volumetric air flow related to the transportation line cross section). It is important to bring in a sufficiently high...

Quite often various production processes shall be handled by only one conveyor. This conveyor is therefore responsible for the handling/loading of the various different powders or granulates, e.g. in chemical process technology or in the color and lacquer industry, where different colors and dyes shall be transported. In such applications the design of the Vacuum Conveyor should permit an easy disassembling and cleaning. At the same time the selected container material must be resistant against cleaning agents and aggressive chemicals. Therefore the stainless-steel modular design was chosen,...
