Vacuum is used with great advantage in order to convey dry powder products through dedicated pipe systems. [PIAB]()’s vacuum conveying systems are built of strong components of high quality. Our objective is to offer solutions that help our customers raise their productivity. Production of food, pharmaceuticals and chemical products demands the highest possible degree of safety as to hygiene and operation. PIAB’s new series of vacuum conveyors has been developed as an answer to the severe requirements of operational safety and hygiene in the food, pharmaceutical and chemical industries.
The result of 25 years’ product development
- All materials have received FDA approval
- Optimized design for the highest standards of hygiene
- Few moving parts for minimized maintenance
- Easy to dismantle and clean
- Modular construction for simple matching to your specific production environment
- Even higher conveying capacity
- New, more efficient vacuum pump
- Higher degree of filtration due to larger filter area and new filter materials
- Best possible traceability
- Grade AISI 316L stainless steel
Principle of PIAB Vacuum Conveying
Vacuum is generated by a compressed air-driven PIAB vacuum pump A. The pump can easily be controlled automatically. Since it has few moving parts, the pump is virtually maintenance-free.
The bottom valve B is closed, and vacuum is raised in the container C and the conveying pipeline D.
From the feed station E the material is drawn into the conveying pipeline and then on to the container.
The filter F prevents dust and fine particles from being drawn into the pump and escaping into the surroundings.
During the suction period, the air shock tanks G are filled with compressed air.
When the material container is full, the vacuum pump is stopped. The bottom valve opens and the material in the container is discharged. At the same time, the compressed air in the filter tank is released and cleans the filter
- When the pump is restarted, the process is repeated and a new cycle begins. The suction and discharge times are normally controlled by pneumatic or electrical control systems H.
Advantages with PIAB Vacuum Conveying
Perfect for powders and granules Industries that produce foodstuff, pharmaceuticals and chemical products have discovered the advantages of vacuum conveying. PIAB, which has developed vacuum conveying systems for 25 years, is the leader of the industry. We provide the solutions to your conveying problems!
Friendly – both to your health as well as to the environment
Different powders require different vacuum levels in order to be conveyed. With PIAB vacuum conveyors you just set the energy consumption exactly according to the prevailing conditions.
From 0 to 20 metres in one second
Time is money. The vacuum technology offers you powder conveying at express speed. Up to 30-metre long systems, the sum of vertical and horizontal conveying.
15 tons per hour
15 tons per hour have been measured at short distance tests with a PIAB vacuum conveyor under favourable conditions.
Easy to install any place
Our systems can be easily adapted to your production environment thanks to few components, small dimensions and low weight. The modular system facilitates the installation. The basic unit is delivered on a drop-key basis. You just have to connect compressed air!
The products are made of stainless, highly polished steel (ASTM 316L). The material is acid-proof and has very strong characteristics. We offer a full 5-year guarantee (filter and wear parts excluded.)
Reliable and easy to maintain
Our systems require a minimum of maintenance. They are easy to clean, and filter cleaning is automatic. Operation and control are fully pneumatic in standard design.
The design of the conveyor and PIAB’s vacuum pumps offer the highest possible operational safety.
The conveyors are, first and foremost, adapted to the food and pharmaceutical industries.
