Benefits
- This double cartridge seal includes the shaft protecting sleeve for the pump and can be fitted without adjusting dimension.
- The pumping ring 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.
- The double mechanical seal's cartridge can be operated with either unpressurised buffer fluid or pressurised barrier fluid. In the event of a sudden barrier fluid pressure failure, the double pressure balanced design ensures that 4KDC's seal faces will not open.
