Suitable for KSB's KWP pump type series
This double cartridge seal includes the shaft protecting sleeve for the pump and can be fitted without adjusting dimension.
The pumping screw circulates the buffer/barrier fluid effectively. The circulation ensures optimum heat dissipation in the space between the two seals.
The double mechanical seal's cartridge can be operated with either unpressurised buffer fluid (quench) or pressurised barrier fluid.
