The GK seals are designed mostly for process pumps used in refining and petrochemical industries, in chemical industry and coking plants, and in particular in pump installations with a high level of explosion risks and increased emissions of volatile substances into the environment. The GK seal requires continuous supplying with filtered barrier gas (most commonly nitrogen) of pressure ~ 0.2 MPa higher than the sealed medium pressure.

The GS is a mechanical seal designed mostly for fans and blowers to seal clean, environmentally friendly gases. It is used as a containment seal in the systems of the so-called dry tandems (system 2NC-CS acc. to EN ISO 21049, API 682), to secure gas leakage into the atmosphere and assume the role of a main seal in case of emergency.

The M1 and M1L seals are designed for sealing shafts of mixers and reactors, in which non-aggressive and environmentally safe products are processed. The seals are adapted for operating with low-pressure installations of flushing-cooling liquids. M1L seals perform the function of shaft bearing unit.

The M2 and M2L seals are designed for sealing shafts of mixers and reactors, in which chemically aggressive and environmentally hazardous products are processed. The seals are adapted for operating with low-pressure installations of barrier or flushing-cooling fluids. M2L seals perform the function of a shaft bearing unit.

The M3 and M3L seals are designed for sealing shafts of mixers and reactors, in which chemically aggressive and environmentally hazardous products are processed. The seals are adapted for operating with low-pressure installations of barrier or flushing-cooling fluids. M3L seals perform the function of a shaft bearing unit.

The M4 and M4L mechanical seals are designed for sealing shafts of mixers and reactors in which thick, high viscosity products as well as chemically aggressive and environmentally hazardous ones are processed. The seals are adapted for operating with low-pressure installations of barrier or flushing-cooling fluids. M4 seals have horizontal or vertical rotation axis and in M4L embodiment they play the role of the bearing shaft unit. The presence of barrier liquid enables seal operation in medium vapours only ("dry" run) and prevents the product from getting out into the atmosphere.

The MS seal is designed for sealing shafts of mixers and reactors in which non-aggressive and environmentally safe products are processed, for dry running conditions. It does not require the application of any auxiliary installations.

PGS shaft seals are radial seals for sealing gases, dust and vapours. They are used to seal the shafts of fans, blowers, mixers, dryers, centrifuges, bearings, etc. They can be used in almost all industries, such as chemistry, power engineering, sewerage technology, petrochemical, pharmaceutical, food industries and marine technology. Shaft seals of machines pumping gases which are inflammable, toxic and contaminated with particulate solids are supplied with neutral barrier gas that prevents the sealed medium from going out into the atmosphere. Barrier gas pressure must be higher than the medium pressure by ca. 0.1-0.2 bar. In case of high temperature applications, barrier gas also cools the seal.

It is a general purpose mechanical seal with a wide range of applications. It is designed to operate with cold and hot water, oils, fuels, not very aggressive chemicals and other liquids contaminated with solid particles. It is recommended for the majority of mediums in the food industry.

The USC is a general purpose mechanical seal. It is designed to work with water solutions, not very aggressive chemicals and other liquids contaminated with particulate solids.

The USP is a mechanical seal used for viscid media containing abrasive particles. USP seal requires the following liquid installations: buffer liquid (API Plan 52 ) or barrier liquid (API Plan 53). Max. pressure of barrier liquid: 1.6 MPa, max. overpressure: 0.6 MPa.
