Mechanical seals and sealing assemblies

We are dedicated to the production of mechanical seals and their overhauls .
We replace, or conveniently repair seals of other manufacturers such as Burgmann, John Crane, Aesseal CSSN, Convertor, Fluiten, Depac, Flowserve, Chesterton, Chetra.

A mechanical seal is a type of seal that prevents the passage of separated liquids and gases around axes, shafts, rods, rods and plungers that pass through a separating barrier.

  • Fluid seals.
  • Seals for the food industry.
  • Seals for other industries.
Type - WRZ
Operating parameters:

Pressure: 1.2 MPa
Temperature: 180 ° C
Speed: 15 m / s
Shaft size: 10-70 mm

Simple non-lightweight mechanical seal with central coil spring. The direction of the spring winding is determined by the direction of rotation of the shaft, which is determined when viewed from the seat of the mechanical seal (from the motor). The external dimensions of the seal correspond to the ČSN EN 12756 standard. It is also manufactured in the cartridge design, it is intended primarily for sealing abrasive liquids and for smaller shaft diameters.

Type - WRX
Operating parameters:

Pressure: 1.6 MPa
Temperature: 200 ° C
Speed: 20 m / s
Shaft size: 18-165 mm

Simple non-lightweight mechanical seal with a set of coil springs. The winding direction of the springs does not depend on the direction of rotation of the shaft. The external dimensions of the seal correspond to the ČSN EN 12756 standard. This seal is intended for a wide range of applications, especially for medium abrasive and aggressive liquids. We also produce a cartridge variant.

Type - WRR
Operating parameters:

Pressure: 1.6 MPa
Temperature: 200 ° C
Speed: 20 m / s
Shaft size: 18-165 mm

Double unloaded mechanical seal with a set of coil springs. The winding direction of the springs does not depend on the direction of rotation of the shaft. The external dimensions of the seal correspond to the ČSN EN 12756 standard; shortened in length. This seal is used to seal liquids, where flushing of the seal space is required, when sealing chemically aggressive media. We also produce a cartridge variant.

Type - WRV
Operating parameters:

Pressure: 2.5 MPa
Temperature: 200 ° C
Speed: 20 m / s
Shaft size: 18-160 mm

Simple lightweight mechanical seal with a set of coil springs. The winding direction of the springs does not depend on the direction of rotation of the shaft. The external dimensions of the seal correspond to the ČSN EN 12756 standard. The lightweight seal is designed for higher pressures of sealed medium abrasive and aggressive liquids. It is also produced in a cartridge design.

Type - WRP
Operating parameters:

Pressure: 2.5 MPa
Temperature: 200 ° C
Speed: 20 m / s
Shaft size: 18-120 mm

Simple lightweight mechanical seal with a set of coil springs that are out of the sealed fluid. The winding direction of the springs does not depend on the direction of rotation of the shaft. The external dimensions of the seal correspond to the ČSN EN 12756 standard. The lightweight seal is suitable for contact with food and if sanitation is required.

Type - WRM
Operating parameters:

Pressure: 2.0 MPa
Temperature: 200 ° C
Speed: 30 m / s
Shaft size: 15-120 mm

Simple lightweight mechanical seal with a set of coil springs. The direction of the spring windings does not depend on the direction of rotation of the shaft. This seal is used when a short seal length is required. The stator length can be shortened up to 11 mm. Allows for several variable layouts, such as double in tandem or face-to-face.

Type - WRS
Operating parameters:

Pressure: 2.5 MPa
Temperature: 200 ° C
Speed: 25 m / s
Shaft size: 20-250 mm

Simple lightweight mechanical seal with a set of coil springs that are out of sealing medium. The winding direction of the springs does not depend on the direction of rotation of the shaft. This seal is suitable for sealing abrasive and aggressive liquids, as well as for contact with food and drinking water. It can also be used in sterile operation.

Type - WRS/C
Operating parameters:

Pressure: 2.5 MPa
Temperature: 200 ° C
Speed: 25 m / s
Shaft size: 20-250 mm

Lightweight cartridge mechanical seal with a set of coil springs that are out of sealed media. The winding direction of the springs does not depend on the direction of rotation of the shaft. Like the above-mentioned HTSVB seal, this seal is suitable for sealing abrasive and aggressive liquids, but also for contact with food and drinking water. It can also be used in the case of sterile operation. The seal is supplied in several versions, eg in the quench version with a sealing ring - flushing the seal with drain to the off or "F" version according to ČSN ISO 9905 - flushing with drain to suction pumps.

Type - WRC
Operating parameters:

Pressure: 2.5 MPa
Temperature: 200 ° C
Speed: 25 m / s
Shaft size: 20-250 mm

Lightweight cartridge cartridge with a set of coil springs that are out of sealed media. The winding direction of the springs does not depend on the direction of rotation of the shaft. This seal is also suitable for sealing abrasive and aggressive liquids, for contact with food and drinking water, and for
sterile operation.
