Non-standard Component Mechanical Seals

Non-standard component mechanical seals are collections of separate parts that you assemble manually to stop leaks in unique machinery. They are not an all-in-one, pre-built unit like a cartridge seal.
Here is the simple breakdown of what makes them different:
Individual Parts: Instead of one sealed unit, you get separate pieces: seal faces, springs, O-rings, and other hardware.
Manual Assembly: You (or a skilled technician) must install and align each piece by hand in the pump or mixer. This makes installation more complex than pre-made "cartridge" seals.
Customization is Key: This "piece-by-piece" approach allows you to mix and match materials and sizes to perfectly suit a machine's unique needs, such as odd dimensions or very specific chemical resistance requirements.
Cost-Effective Option: They generally have a lower initial price than all-in-one cartridge seals.
Requires Expertise: Because proper alignment is vital for them to work, they require more skill to install correctly.
In short, non-standard component mechanical seals are the versatile, customizable, and often cheaper option for sealing unique industrial machines, but they require expert handling during installation.
