Mechanical seals
Mechanical seals from ttv - the flexible packing system with innovative technology

For applications with low speeds and the risk of dry running or insufficient lubrication.

The ttv mechanical seal is a flexible packing system with an innovative technology.

There are no sealing surfaces or springs and nothing in the cartridge is fragile. The seals use a flexible sealing compound as the sealing medium, which remains compressed in the system. The sealant is held at a pressure slightly above the pressure to be sealed by a gas-operated piston.

The sealing material acts as an adaptable stationary seal and thus compensates for shaft movements without affecting the sealing quality.

Description

ttv mechanical seals are adaptable models and are therefore available in the following versions:

Split seals
Cartridge versions with integrated bearing
Versions to compensate for increased radial misalignment
Seals with upstream cooling flange
Versions in accordance with Atex

Areas of application

ttv mechanical seals are used in many areas, e.g:

Screw conveyors
Vacuum dryers
Ball mills
Screw pumps
Rotary valves
Rotary valves
Agitators
Mixers

Advantages

Easy installation thanks to pre-assembled units
Long maintenance intervals
Robust design with high fault tolerance during installation and operation
Permanently technically tight
High sealing function ensures a clean system environment
Cleaning options in accordance with CIP/SIP possible
Maintenance cost savings
Low contamination due to the sealing compound

Properties

With its low maintenance requirements, the ttv mechanical seal is an excellent alternative to stuffing box packings and mechanical seals with a supply system.

Frequently asked questions

How does ttv and its products adapt to the constant changes and demands of the market?

Our engineering solutions team works closely with customers and our production management at R&D level. This ensures that we always have the latest designs and materials available.

How should elastomers be stored so that they retain their functionality and service life?

With the exception of uncured rubber blends, the characteristics of properly stored and treated rubber products usually remain virtually unchanged for a few years. The physical properties of a large proportion of rubber products will change if the products are treated incorrectly or stored in unfavourable conditions. Factors such as heat, moisture, light, oxygen, ozone or solvents, or stor-age under tension can reduce the service life of the products or render them unusable.

Details you can see in our "Instructions for storing elastomers".
