Compact mechanical seal 4kdc
This double cartridge seal includes the shaft protecting sleeve for the pump and can be fitted without adjusting dimension.
Dependable mechanical seal 4kdc
Given the stationary design, the springs are located outside the fluid handled and thus protected from contamination.
Robust mechanical seal 4kdc
The pumping screw circulates the buffer/barrier fluid effectively. The circulation ensures optimum heat dissi- pation in the space between the two seals and thus increases the service life.
Versatile mechanical seal 4kdc
The double mechanical seal’s cartridge can be operated with either unpressurised buffer fluid (quench) or pressurised barrier fluid.
Safe mechanical seal 4kdc
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.
