Mechanical seals

We supply single-acting, double-acting and triple-acting mechanical seals. They are all designed for agitator applications for adaption of significant shaft displacement.

The following types of seals can be offered:

Dry running single acting seals contact seals
Dry running double acting gas lubricated seals
Liquid-lubricated double acting seals.
Liquid-lubricated triple acting seals.

Single-acting mechanical seals

Our assortment consists of 3 different single-acting mechanical seals. They are most suitable for biofuels and bio refineries, storage tanks, speciality chemicals and formulated consumer products.

Here is a description of the overall functions and applications of the 3 mechanical seals:

Two seal rings with one interface
Dry-running or lubricated mechanical seal
Suitable for low pressure applications
Vessel temperature range from -20 – 230 degrees Celsius
Operating pressure range from vacuum-7 bar
Shaft size range from 20-220 mm
Sliding speed 0-5 m/s

Double-acting mechanical seals

Our assortment consists of 6 different double-acting mechanical seals. They are most suitable for bulk chemicals, polymers, pharmaceutical products and cosmetics, specialty chemicals, formulated consumer products, biofuels and bio refineries, hydrometallurgy and storage tanks.

Here is a description of the overall functions and applications of the 6 mechanical seals:

Double acting mechanical seal liquid lubricated
For applications in the low to medium pressure range
Use of FEA ensures optimized stress distribution in every seal ring
Suitable for frequent changes in pressure
Sterile seal construction available
Vessel temperature range from -50 – 400 degrees Celsius
Operating pressure range from vacuum -100 bar
Shaft size range from 40-300 mm
Sliding speed 0-20 m/s

Triple-acting mechanical seal

We offer a triple-acting mechanical seal suitable for high pressure application and for extreme toxic and explosive products within the speciality chemicals and hydrometallurgy.

Here is a description of the main functions and applications of the mechanical seal:

Liquid lubricated for extreme pressure applications
Third pair of seal rings forms a second seal liquid chamber
Function in emergency situations: if one pair of seal rings fails, the seal operates as a double-acting mechanical seal
Vessel temperature range from -50 – 400 degrees Celsius
Operating pressure vacuum - 200 bar
Shaft size range from 40-220 mm
Sliding speed 0-3 m/s
