1. Large empty space above the seal faces
Solid matter is flung outwards off the faces by the centrifugal force.

2. Split-pin for holding back the springs
The springs do not pressurize the seal faces until after the split-pins are removed when the installation work is finished.

3. O-rings with integrated connection pins
An absolute innovation for split mechanical seals. Installation is made safer and easier as the result.

4. Housing centering elements
Another innovation which makes installation extremely easy because the pins do not need to be removed when the seal is fully installed.


Type 390
Single Mechanical Seals
  • Split mechanical seals
  • Fast, easy and reliable installation
  • Effective alternative for media with solid materials
  • Best sealing alternative for large-scale units
  • Lowest contact pressure for the longest possible service life
Convincing Arguments!

This new, split mechanical seal proves once again that the DEPAC business and product philosophy is focused on providing benefits for its customers.

Perfect technology, high reliability and the lowest possible purchasing and operating costs are paramount.

Equipment fitted with split mechanical seals works without leakage and does not have to be dismantled in order to replace the seal or its parts.

Production losses and expensive, time-consuming maintenance are avoided. This applies in particular for large and complicated machines.

The higher price of a reliably working, split mechanical seal stands in no relation to the potential expense of installing a non-split mechanical seal!
Notes
DEPAC's latest development of the split mechanical seal is the ideal option for large and heavy-duty machines with rotating shafts which require sealing and for equipment which needs a great deal of work to change a mechanical seal.
Often there was no choice but to use packings on these machines, in spite of their known drawbacks. These were taken into the bargain because of the unjustifiably high cost of mechanical seal maintenance.
DEPAC's new, split mechanical seal combines in optimum manner the advantages of a packing which is easy-to-change with those of a mechanical seal which is leak-free, optimized for life and operationally efficient.
