Manfaat

Single cartridge mechanical seal, stationary design.
Designed for installation in vertical pumps for applications with high pressures and speeds.
The stationary design ensures that the sealing clearance is positioned closer to the impellers. This lowers the risk of dry running in the event of a gas pocket forming in the seal chamber.
