Mechanical seals manufacturers are available as: single, double complete with pumping ring, single with V-ring, single and double seals capable for dry running.
All of these seals are suitable for DIN and ANSI type flanges, which have very limited radial and axial dimensions and are ideal for pumps, industrial mixers, fans and other equipment.
The cartridge assembly minimises installation problems to a minimum and is suitable for most applications.
There is also a version available with a thicker shaft sleeve and larger internal clearances designed for fitting to equipment and industrial stirrers that are submitted usually to substantial mechanical stresses, oscillation, vibration and run-out.

Mechanical seals manufacturers are used for the sealing of rotating shafts against a stationary housing, e.g. in pumps and agitators. The stationary" part of the industrial seal is usually located at the housing, the rotating" part is fixed on the shaft. The high-precision face-machined sliding faces rotate axially in opposition. The sliding faces are pressed against each other by means of spring force, thus preventing the opening of the seal. The seal faces are statically sealed against the housing and the shaft by secondary seals (O-rings). With the entry of the pumped medium into the minimal sealing gap a lubricating film is generated and the sealing effect is thus obtained.
The design, arrangement and combination of materials of the seal is basically determined by pressure, temperature, speed of rotation and quality of the pumped medium. Shaft diameters of 5...500 mm, pressures from 10 torr ....250 bar, temperatures from -200°C... +450°C and sliding velocities up to 150 m/s limit the operating range of mechanical seals. Additional seal supply systems or buffer fluid systems may be required, dependent on the mode of operation, the quality of the medium and the seal arrangement.. |

Seals have been developed to operate on propeller shafts of small, medium and large size boats where a high level of reliability is required.
The special design allows large axial displacement and the use of suitable material guarantees as well as high resistance to corrosion and high mechanical resistance to withstand stresses produced by vibrations.
The installation of mechanical seals suppliers in this particular field has solved problems such as corrosion during long periods of inactivity and shaft damage caused by traditional stuffing boxes. Power absorption is considerably reduced as well.

Split mechanical seals manufacturers are employed on a wide variety of pumps or large machinery, where the time available for maintenance operations is limited.
Our sophisticated design allows the production of mechanical seals, which are completely divided in two halves, suitable to be installed without dismantling parts of the machinery. In addition, the special design of the industrial seal flange makes it suitable to be installed on existing pumps and industrial mixers.
With cartridge execution, all components are pre-assembled in two halves, eliminating any possibility of incorrect installation.
