Mechanical seals are becoming superior packing options and so they could possibly be the conventional or cartridge type. Conventional seals, however require setting and aligning on pump sleeve and shaft to be effective properly. This requirement increases error margin that leads to premature failure and requires more maintenance costs. It’s to reduce these challenges that cartridge seals were developed.

What they are

Cartridge seals serves as a self-contained units that are composed of the seal, gland plate and shaft sleeve. They are created in a way that they can eliminate common failures especially from installation errors.

The gland needs to be tightened evenly so if your collar set screws and spacers removed. Your cartridge unit can come fitted onto the pump shaft like a pre-built whole assembly, hence you won’t require any further alterations in fit. Make sure that you install the seal around the pump first before attaching to seal chamber. The reality that the seals usually do not call for usual adjustments and setting measurements, the maintenance prices are greatly lowered along with the common seal installation errors can also be minimized.
