Why Agitator Mechanical Seals
Shaft seals for agitators, mixers and reactors — top-entry, side-entry and bottom-entry configurations.

- Seal faces: SiC/SiC, SiC/TC, ceramic/carbon — matched to your media, not sold by price
- Elastomers: EPDM, FKM (Viton), NBR, PTFE with chemical compatibility guidance
- Standard shaft sizes 6-120 mm, metric and inch; cartridge and component options
- Factory-direct pricing from the Ningbo seal cluster — 1 piece to container loads
- Honest duty guidance: real pressure/temperature windows, no overpromising
How Agitator Mechanical Seals Work
A mechanical seal keeps pumped media inside the pump where the shaft passes through the casing. Two precision-lapped faces — one rotating with the shaft, one stationary — ride on a microscopic fluid film that seals while allowing rotation.
Selection Basics
You need four numbers: shaft diameter, seal bore, operating pressure and temperature — plus your media. With those, we match configuration, face material and elastomer. Send them and we do the rest.
What We Do Differently
No fake "never-leak" promises. We tell you which seal fits your duty window, how to install it right, and what shortens seal life — honesty that keeps your pumps running longer.
