REMEX® Agitator Seals

STB is a well-known and established partner in the designing and manufacturing of mechanical mixer seals. We offer mixer- and agitator seals as single cartridge seals and as double mechanical seals. Each type is equipped with a number of barrier fluid-, flush- and grease connections. To increase the life- und runtime of the seals, we offer wide range of seal support systems.  All steel components are made out of stainless steel SS316Ti for the best achievable chemical resistance.  Other material are available upon request.

Increase Your Efficiency

STB Mixer Seals are according to several Norms, the following standardized are listed:

Agitator seal with standard flange, according to DIN 28137.

Standard-flansch-flauschdichtung-flausch-standardflausch

Agitator seal with cooling flange with can also be used as heating flange. Ideal for reactors and agitators with work at extreme temperatures.

To Monitor the processes and leackage rate of agitator seals, different variations of flanges with integrated leakage drain are offered.

The integrated dispersion barrier offers the possibility to go easy on seal faces and avoid tearing moments in processes in which the product would crystallize in situations of machine downtime or even through the whole process.

Dispersion-Sperre-polymerization-barrier-flange

In reaction processes, in which a metallic contact must be excluded, we offer the opportunity to design flanges with special materials, e.g. glass-line (enameled), to fit to your processes.

Our engineering staff can adapt our agitator seals to every agitator to fit your needs.

Our mixer cartridge seals can perform at lowest revolutions and sliding speeds, highest pressures, while not making any excuse in references to the running times. Seal face dimension and shapes will be adjusted for special requested mixer seals, to increase the life time of the seal. In cases where contact of the product with stainless steel is prohibited, we offer non steel or enameled parts. In high- or low temperature surroundings and -areas we have optionally cooling and heating flanges which can be integrated easily. In cases with low lubrication, shape adjustments of the seal faces and special dry running mixer seal faces can be chosen to increase the life time and performance of the seal.

phREMEX

Antibacterial sealface

The phREMEX belongs to the REMEX family of brands and offers a good alternative with very high availability for agitator seals from the food and pharmaceutical industry. REMEX stands for consistent quality across all product lines. A special advantage is that the agitator seals of the REMEX® product family make easier installation by their construction. This holds the complete components of the seal in the housing together. Thus, only the housing of the REMEX® is mounted on the agitator housing.

Our agitator seals are offered as standard with the following DIN specifications:

This norm regulates the flanges of mixers.

Double mechanical- and single mechanical mixer seals are according to the Norm 28141. This type of seal is designed for shaft ends according to DIN 28154, shaft ends and flanges according to DIN 28141.

Single and double mechanical mixer seals can be delivered with an enamelled flange to the product site. The flange is in accordance norm DIN 28137-2 and in reference to shaft ends (DIN 28144 & DIN 28158).

As a standard, STB mixer and agitator seals are designed in accordance to DIN 28138-3 for connection positions. This norm regulates the connections for the layers of the pipes and fittings.

The DIN 28154 is reports about the design of shaft ends of rotating equipment, especially mixer and agitators. Mixer seals are commonly designed according to DIN 28154, but in addition each seal is offered with smooth shaft ends. For shafts with non-standard diameters modular systems will be transferred to keep lead times as short as possible.
