mechanical seals
with UNITEN dimension
under EN 12756 European norms

Serie 7K

Bidirectional mechanical seal

with short axial length.

For internal or external mounting.

Available in all steels, special alloys,

hard facings or metals,

solid silicon carbide...

Ideal with high or pulsing

counterpressure, with viscous or

sticky fluids.

Serie 82 

Bidirectional mechanical seal.

Drive made by the screw

which locks onto the shaft; seal faces

held in contact by the spring.

Application and available materials

similar to Roten Type 2 seal.

Limited axial length and compact shape

ideal for confined spaces.

Serie 84

Bidirectional mechanical seal as Serie 82,

with PTFE gaskets.

Application and available materials

similar to Roten Type 4 seal.

Particularly reduced axial length and

compact shape allowing easy mounting.

Serie 85

Bidirectional mechanical seal;

interchangeable seal faces;

compact; minimal axial length.

Large range of material.

Serie 85E

Balanced and bidirectional mechanical

seal, without shaft steps;

interchangeable seal faces;

compact; minimal axial length.

Large range of material.

Please contact us for more information.

Serie EHS

Balanced and bidirectional seal;

for high pressure, dirty or viscous liquid;

easy to clean and appropriate in sterilized

environment (e.g. application in food,

sanitary and pharmaceutical industry).

Please contact us for more information.

Serie 1 = Serie 22

Mechanical seal with self driving

spring that directly clenches the

wedge and with driving radial hook.

Made of massive material, hard -e.g.

carbon, ceramic, silicon carbide or

anticorrosion tungsten carbide...

Available in customized sizes.

Serie 2, Serie 4 (PTFE-Keil)

mit massiver Gleitring

Mechanical seal dependent of the

rotation direction.

Made of massive material;

Hard/soft friction faces.

Appropriate to the transport of clean

or aggressive fluids.
