STAG manufactures manual gate valves where the flange dimensions are customized according to customer requirements.

In addition to fluidization, STAG uses Fluid Floors for silos with multiple outlets. The entire silo floor is equipped with a fluid cloth and enables the bulk material to be stored to flow off constantly and completely.

High volume flows over short distances? Please contact us for further information.

STAG employs bulk material-specific designs for fluidisation.

The Fluid Channel is installed with a slight incline, and thanks to the large-area aeration, even difficult-flowing products can be discharged without any issues.

The closed STAG Conveyor Belt stands out through its dustproof design and its integrated scraper floor. With this construction method the conveyor belt can be operated by a slight vacuum. Provided suction socket at the connectors are the interface to the dust extraction. The integrated scraper floor will be periodically connected and supports dust to the…

STAG’s standardized conveyor belts are characterized by their high load capacity and high-quality materials. With their scalable design, even the most difficult challenges can be mastered.

STAG offers foreign body traps and sieves for a wide range of applications. Special deflection heads are used in conveying lines, STAG develops customer-specific prototypes in down pipes and a standardized design is used for the Impact Mill.

Gravimetric dosing dispenses bulk materials precisely by weight, with linearly adjustable quantities, thereby ensuring consistent, flexible and efficient processes.

Coarse particle separators are used in mechanical conveying processes of bulk products in order to eliminate larger particles (impurities). The benefits are an improved operational safety of the conveying system, which can be reduced in size after the coarse particle separator. It is possible to incorporate a CPS in an open or closed (dustproof) conveying…

Trough Chain Conveyors are continuous conveyors suitable for transporting all types of bulk materials. The STAG Trough Chain Conveyor meets the highest demands in terms of temperature and abrasion.

The Injector / Air Blast Nozzle is suitable for pneumatic conveying in continuous dilute phase transport of non-abrasive or slightly abrasive products.

By using the STAG Lump Breaker, even the hardest lumps are crushed, and thanks to the design of the knives, the oversize material is reduced to a defined particle size.

The STAG Multi Screw Dosing Unit is a precise volumetric feeder with multiple screws and optimized internal geometry, which reliably prevents air pockets. Each revolution delivers exactly the same amount of material, and the unit is supplied as a complete drive system including the motor and gearbox.

Processing of the entire particle size spectrum with the compact STAG mill. With the adjustable impact mechanism, the bulk material is crushed to a particle size distribution that is uncritical for pneumatic conveying.

The STAG Sampler is a high-precision solution for reliable sampling in industrial environments. Designed to meet the demands of various industries, this sampler offers easy handling and precise results. With its robust construction and innovative technology, it ensures efficient and accurate sampling for analyses and quality controls. The STAG Sampler helps companies optimize their production…

The STAG Tubular Screw Conveyor offers a reliable and flexible solution for bulk material transport at inclinations of 0 to 45 degrees. Thanks to its full-flight screw and variable pitch in the intake area, it can be precisely adapted to different requirements.

The STAG Sand Seperator is primarily used in the sand and gravel industry. It recovers sand from wastewater and increases the quality of the final product.

The Push Floor is particularly suitable for difficult-flowing bulk materials such as wood chips, up to and including pasty products such as sewage sludge.

The STAG discharge and dosing module with two bulk material slide valves and a flexibly dimensionable intermediate container is versatile and optionally available with air cooling for high temperatures.

The mechanical discharge aid “Silex” is used for poorly flowing and difficult to non-fluidizable bulk materials and is easily retrofittable due to its low installation height.

STAG’s pneumatic railcar unloading systems have been successfully used for a wide range of bulk materials for over 70 years.

The different operating modes—manual, semi-automatic, and automatic—are used to start, interrupt, and end conveying. Operation is conveniently carried out via a touch panel.

The STAG Drum Washing Machine is ideally suited for processing and thoroughly cleaning gravel, tailored to the type and degree of contamination.

The STAG pressure/vacuum relief valve is used as protection against excessively high or low pressure conditions in containers and silos. If there is excessive overpressure in the container, the weight in the overpressure section is pushed upwards, air escapes, and the pressure drops. The escaping exhaust air is then directed via a connected pipeline to…

The large cross-section and large volume of the pot create a stabilization zone within it. This results in pulsation-free pneumatic conveying.

Underfloor filling ensures gentle and segregation-free conveying of bulk materials directly into the silo.
