For safe and successful production:The patented interseal dry9000® seal for agitators and mixers.

interseal dry9000®:Makes the weakest link become a success factor

Many agitators and mixers are still using conventional sealing

systems which require extensive maintenance. Typically they

are vulnerable to the occurring axial and radial movements in

your mixers. Even upon the intended use of conventional sealing

technologies there may also occur contamination of your product.

This is avoidable!

Our patented seal interseal dry9000® offers the standardized

solution for your

» Agitators

» Mixers

» Thin film evaporators

» Screw conveyor

» Pressure nutsch

» Rotating filters

» Specific applications

Runs dry, is 100 % leak proof and ensures that your productivity runs permanently smoothly.

The specially developed tribological system between the shaft protection sleeve

and the sealing lips ensures that no liquid or gas has to be used – the dry9000® runs

completely dry. This is why the interseal dry9000® system has no need of any supply

systems such as a thermosiphon tank and systems to pressurize blocking media.

Due to the patented arrangement of compensation parts, the dry9000® sealing lips

are completely free of forces. By being completely leak proof our shaft seal reduces

the risk of a production loss to an absolute minimum and protects people and the

environment.

3

Challenges are welcome – the dry9000® follows every movement.

Whether motion is abrupt, vibrating or lurching: With a conventional

shaft sealing the deflections that are acting as forces in the production

process lead to gaps on the sealing surface. This results in wear

followed by leakage through to the failure of the seal.

This demonstrates the superiority of our shaft lip seal, as the

interseal dry9000® follows the movements of the shaft.

Conclusions: As there is no relative movement of the actual

sealing components, no medium can penetrate the sealing zone.

DIN, ATEX, TA Luft, GMP and FDA – Standards you can rely on

» Plug & play dry9000® cartridge for steel, VA and glass-lined vessels according to DIN 28136

The connecting dimensions of the mounting flanges comply with DIN 28141 and DIN 28137,

the shaft ends comply with DIN 28154 and DIN 28159.

» Meets all security requirements that are summarized in the ATEX directives.

» The sealing system is compliant with TA-Luft.

» The seamless production process guarantees GMP-compliance for all products.

» Cavity minimized design.

» All product contacted parts are available in FDA-compliant quality.

One of the decisive

advantages of the

dry9000® is that the axial

and radial movements

of the agitator or mixer

shaft have no effect

on the sealing system.

from 40 to 140 mm the appropriate dry9000® is available from stock.

Right for you: your customized standard solution.

For various reasons some machine manufacturers waive the requirements of the German

industrial standards. But this is no problem for us! interseal simply customizes the dry9000®

to your requirements.

Develop advantage: our custom-made special seal for your environment.

Does your production occur in an exceptional environment? We are ready to take up the

challenge. Upon request we develop an adapted variation of the dry9000® that meets your

The standard sealing packages of the dry9000®

Throttle version

A spring-loaded PTFE stripper ring on the

product side in front of the first sealing lip

protects the sealing package against coarser,

abrasive or adherent media.

Sealing lips version

A metallic lip on the product side serves as

protection against coarser, abrasive or adherent

media. Highlight: the cavity at the sealing

package is reduced to an absolute minimum.

High-pressure version

An in itself supporting sealing set up ensures

the stability of the sealing lips upon high

pressures. The metallic lip here also protects

the sealing package against coarser, abrasive

or adherent media. The cavities in the seal

are completely minimized.

13

Sealing lips layouts

The optimal sealing lips layout for the dry9000®

depends on the design pressure of the production

process. The standard layout provides constant

sealing at pressure and a reliable constant

vacuum. Other versions provide a conformed

layout of the lips according to the operating

conditions.

Hole for optional shielding gas

Between the product-side throttle ring and

the first sealing lip is a hole that can be used

to input shielding gas (to take away the

product from the seal), to sterilize or also

for the separation of zones.

Hole for temperature monitoring

This hole allows the temperature monitoring

of the seal. The temperature is checked

at the optimal point of the source of heat.

Hole for service inspections

In front of the second-last sealing lip from

the atmosphere the seal has got a service

inspection hole. The seal remains fully

operational and sealed if the product

pressure is measured at this hole. This

allows an efficiently planned review.

The innovative movable stripper for the dry9000®

A movable stripper that acts like a snow pusher

can be installed in front of the dry9000®. This

stripper prevents that media gets to the primary

sealing package, although the shaft is moving

axially or radially. The stripper with the metallic

protected sealing lip is radial flexible. This avoids

splitting between the sealing lip and the protection

sleeve which is tumbling with the shaft.

Furthermore the movable stripper is an optional

protection against quickly adhering product.
