What is cartridge sealing?

The cartridge mechanical seal is a completely enclosed sealing system with pre-assembled components. Usually, this seal type consists of glands, sleeves and other hardware that may be pre-assembled.

For a more exhaustive list, please refer to the blog post about different mechanical seal types.

Advantages of cartridge mechanical seal

The main benefits of choosing a cassette seal for your pump seal system include:

Easy installation (no expert required)

Since the pre-installed seal has a fixed axial arrangement, it has higher functional safety. Eliminate measurement errors.

Eliminates the possibility of axial misalignment and the resulting sealing performance problems

Prevent dust from entering or damaging the sealing surface

Reduce installation costs by reducing installation time = reduce downtime during maintenance

Reduce the potential for pump disassembly to replace seals

The cartridge unit is easy to repair

Protect customer shaft/sleeve

Due to the internal shaft sleeve of the seal box, a balanced seal can be operated without a custom shaft.
