Mechanical seals provide for the greatest possible cost-effectiveness and operational reliability of pumps, compressors and reactors, because the majority of all repairs to pumps can be attributed to sealing problems. DEPAC considers it its duty to optimise this circumstance. The mechanical seals from the manufacturer from Liechtenstein guarantee the carefree, efficient operation of your plant!

Supply systems ensure process reliability and extend the lifetime of a mechanical seal.
Mechanical seals are necessary to retain the pumping medium in the system circulation in plants in which rotary shafts are in use (for example pumps, compressors or agitators). A mechanical seal consists of two faces that are pressed together by means of axial force. In between them is a liquid lubricating film.
Mechanical seals are available in dynamic and stationary designs. The advantage of a mechanical seal with a stationary design: The spring elements are located in the stationary part of the mechanical seal system and thus cause no additional vibrations. Scoring on the sleeve, for example, is avoided as a result. The sleeve is thus no longer a wearing part - and can significantly reduce maintenance costs. The general rule is: stationary mechanical seals are more reliable than dynamic ones.
The mechanical seals from DEPAC are adapted individually to the required area of application. There are standard solutions on the market for all chemicals or media that have to be sealed by a mechanical seal - but they often lead to considerable problems in operation. The individual adaptation of the mechanical seal to the boundary conditions of the application prolongs their service life enormously. An example? A ten percent change in the concentration or a temperature difference of ten degrees can completely change the behavioural pattern of the media - and hugely impair the function of the mechanical seal.

Mechanical seals are only a small part, but an enormously important one for the operational reliability of pumps, compressors and reactors. Above all with larger plants and units, faults can lead to elaborate maintenance and repair measures and cause high costs. The problem: essential standards are limping a long way behind technological developments. For that reason seals that aren't state of the art are still installed all too often, even in modern plants. The spare part market is therefore extremely lucrative for many pump and unit manufacturers.
As a small and independent manufacturer of mechanical seals, DEPAC has chosen to take a different route. The main innovation drivers for us are process safety and market transparency. The mechanical seals from DEPAC are more expensive to purchase than conventional seals. If one considers the entire life cycle of a unit, however, our customers save money and a whole lot of trouble.
