Health and Safety 



STB designs and manufactures various mechanical cartridge seals. Its state-of-the-art manufacturing technology and short lead time for customised seals are some of the key benefits. Seals are customised based on application, dimension, and materials.  

Single Cartridge Seals 

Single mechanical cartridge seals are an extension and improvement of single component seals. Designed with shaft sleeves, to protect the shaft from damages. Most types are designed with integrated flushes, which are ideal for high viscosity products or products with a high amount of solid particles.

Double Cartridge Seals 

Double mechanical cartridge seals have a barrier or buffer fluid between both pairs of seal faces. One pair is located on the product side, the other pair is located on the atmospheric side. Between them is the barrier fluid to cool the seal faces and to ensure that no contamination of the environment will occur.

OEM-Replacement Seals 

STB offers product specific OEM-Replacement seals. STB provides mechanical seals for equipment such as: turbines, pumps, compressors and blowers. STB pays great attention to delivering the highest quality from design to delivery. Their automated production processes allow STB to have high availability and fast reaction times.
Replacement Seals for the following OEM systems:

  • Blackmer Pumps

  • Plunger Pumps 

  • Screw Spindle Pumps 

  • Sulzer Agitators 

  • Slurry Pumps 

Agitator Seals 

Agitator seals have been used in large-scale industry for many years for sealing critical and dangerous media. The reliable sealing process plays a significant role for the environment and machinery operators. Agitator seals manufactured by STB GmbH meet the highest standards when it comes to its sealing function, lifespan and maintenance requirements. STB's standard series are always readily available and at short delivery times.

Component Seals 

Component mechanical seals are the simplest design of mechanical seals and are commonly used as a better alternative to dynamical packing systems. The design of a single component mechanical seal can include the following components: stationary seal face, dynamical seal face, springs, O-rings and steel parts. The construction in length, pressure resistance, and diameter can vary. STB also develops and manufactures special seals based on customer requirements.

Marine Seals 

STB water-lubricated propeller shaft seal is an ecological and economical solution that meets all technical needs for a modern mechanical navy seal. Among others it has a modular setup, is easy to assemble, requires low maintenance efforts and no configuration. Propeller shaft seals use the same function principle as mechanical seals. Therefore, they are virtually leak free and leave no oil or grease residue in the waterway.

Mechanical Seal Support System 

With the massive global expansion of double mechanical seals in the petrochemical, pharmaceutical and process industry, support systems are a necessary solution. Mechanical Seal Support Systems (MSSS) are able to extend the lifetime of a double acting mechanical seal and increase the equipment’s safety massively.
