Specifications

Compact
This double cartridge seal includes the shaft protecting sleeve for the pump and can be fitted without adjusting dimension.
Dependable
Given the stationary design, the springs are located outside the fluid handled and thus protected from contamination.
Robust
The pumping screw circulates the buffer/barrier fluid effectively. The circulation ensures optimum heat dissipation in the space between the two seals and thus increases the service life.
Versatile
The double mechanical seal’s cartridge can be operated with either unpressurised buffer fluid (quench) or pressurised barrier fluid.
Safe
In the event of a sudden drop in the barrier fluid pressure, the double pressure balanced design ensures that 4KDC’s seal faces will not detach.
The space between the two mechanical seals is flushed with a buffer or barrier fluid, depending on the application. This completely absorbs any leakage of the fluid pumped. In addition, the heat is transported away from this area. The double pressure balanced mechanical seal can be operated with pressurised barrier fluid or unpressurised buffer fluid.
