Mechanical seal Type 270

Mechanical seal type 270

The DEPAC mechanical seal type 270 is a stationary single-cartridge seal that is extremely well suited for conversions from gland packing to mechanical seal, since modification of the unit is not usually necessary. The stationary design principle developed by DEPAC for the process industry also offers maximum running reliability even in difficult ranges of applications for mechanical seals.

Advantages

Stationary design principle
Ideal for conversions from gland packings to mechanical seals
Extremely well suited for standardisations
Cartridge-mounted
Balanced
Independent of the direction of rotation
Multiple springs made of Hastelloy C
Springs outside the medium - no blockage of the springs
Vibration-dampend stationary face support
