The Right Diverter for Your Application

Our Diverters are Designed for Long Durability and Exceptional Reliability

The range extends from cost-effective standard solutions to custom-made options – in every case, we know the right direction. Various designs, surface finishes, materials, and sealing options are available.

The Zeppelin Systems diverter portfolio offers the right solution for every application. The selection depends on the size of the connected pneumatic conveying line, the maximum occurring conveying pressures, and the properties of the bulk material being conveyed. Diverters can be designed as distribution diverters or collection diverters. Whether dealing with high-purity plastic granules, powdered food materials, sticky pigments, or highly abrasive mineral bulk materials, Zeppelin Systems provides the perfect diverter. We choose materials and sealing materials based on the application, always focusing on long-lasting and reliable operation. You can rely on our diverters!

Key Advantages at a Glance:

High Purity and Less Waste: Optimized inlet and outlet geometries ensure gentle material handling through the diverter.
Lower Energy and Gas Consumption: Due to optimal and individually tailored sealing systems between the rotor and housing.
Long Service Life, Extended Maintenance Intervals, and Low Repair Costs: Achieved through the selection of suitable materials and reliable sealing systems.
No Material Carryover: Thanks to a dead-space-free internal geometry.

Our airlocks are certified, and in specific cases, also country-specific certified

Our diverters are used in various industries

Außerhalb der folgenden Beispiele können unsere Schleusen auch in weiteren Branchen zum Einsatz kommen. Nehmen Sie gerne Kontakt zu uns auf, um zu besprechen, ob unsere Schleusen für Ihre Applikation zum Einsatz kommen kann – WE CREATE SOLUTIONS!

Food and Beverage

Typical applications include steering bulk material flows such as flour, sugar, and salt in downpipes or pneumatic conveying systems. Various bulk materials in the animal feed sector and other applications are also directed using the diverters. Special attention is given to good cleanability and minimal material carryover:

Seals made of plastic therefore have the appropriate food-grade certification.
In the food industry, all product-contacting surfaces are generally made of stainless steel.

Plastics

Plastic powders and granules, such as polyolefins, compounds, and engineering plastics, are conveyed and redirected into different directions using diverters. To ensure this happens as gently as possible without abrasion, Zeppelin Systems offers interesting variants:

For high-quality powdered or granular bulk materials, various sealing options are available.
Shock-free Internal Contours prevent unwanted material stresses that could cause abrasion in the form of powder or angel hair.
Generally, the interior rotors in pipe diverters feature a stainless steel pipe insert. The flange necks of the pipe diverter housings can also be equipped with stainless steel pipe inserts upon request.
Additional weatherproof covers, with or without heating, allow the use of pipe diverters even at extremely low ambient temperatures.

Chemistry

In this industry, handling powders, which can range from easily to difficultly flowable and often abrasive bulk materials, can be challenging. However, Zeppelin Systems offers numerous solutions to safely guide even the most demanding products in the right direction.

For very abrasive bulk materials, inflatable seals are available.
In certain applications, additional purge gas units prevent powdered, abrasive materials from settling between the interior rotor (rotor) and housing in the sealing area.
For highly abrasive materials, diverters with hardened stainless steel pipe inserts or diverters with ceramic lining are also available.
The sticking of very sticky bulk materials, such as pigments, can reliably be prevented with flexible hose diverters.
When using seals on the inside of the housing, all three pipe outlets can be sealed simultaneously. This also prevents reverse pressure on the non-activated pipe outlet.

Rubber & Tire

In tire manufacturing, the base materials are typically carbon black and silica, along with possible additional additives. Zeppelin diverters ensure reliable bulk material redirection in pneumatic conveying lines with bypass systems. There are various options available:

For tire carbon blacks, aluminum castings, hard-coated as standard, are used for the diverter housing and interior rotor (rotor), which significantly reduces the adhesion of carbon black.
Typically, gland packing seals are used as static seals on the interior rotor.
For highly adhesive technical blacks (pigments), flexible hose diverters are also used

Rotary feeders

The right airlock for your application

Dosing, feeding, discharging – Rotary airlocks from Zeppelin Systems keep bulk materials in motion. They ensure safe feeding into pneumatic conveying systems, relieve subsequent components under silos, and take on dosing tasks.

Sampler

Safe Sampling for the Highest Product Quality

When it comes to controlling suppliers, securing the production process, or evaluating the quality of the final product, representative samples of the bulk material must be taken. Sample takers from Zeppelin Systems provide safe sampling of flowable powdered or granular bulk materials from silos, containers, downpipes, or pneumatic conveying systems. The sample can be taken under normal atmospheric conditions or within a pressure range up to 1 bar(g).

Dosing & Conveying screws

We've Got It Down!

The dosing and conveying screws from Zeppelin Systems dose and transport bulk materials of all kinds. Additionally, they are also suitable for precise scale filling. The screws can be optimally adapted to the specific application. For example, a hygienic version with quick cleaning is available for baby food production, as well as dust-tight versions for handling powders.
