Advantage of New Flygt® pump seal
1. In this new design a wave spring replaces the coil spring for complete
seal balance.
2. Stainless steel material replaces plastic materials to improve
temperature resistance and strong impact forces.
3. Screw sets create a better seal connection and better functioning at
high running speeds "We now supply this seal in shaft dimensions of
20mm / 25mm / 35mm. We can also custom design this seal to your
requirements and pump housing!"
