Seal DF-SA Advantages (HBDF-SA)
- Resistant to electrochemical corrosion.
- Extremely long service life (>40,000 h).
- No dosing system, no cooling circuit conditioning required.
- Diamond coating provides very low friction, thus reduced power consumption.
- Deformation-optimized for high sliding velocities and medium pressures.
- Economical due to standardized components.
- High flexibility due to adaptation of the connection parts to the pump seal chamber.
- Optimum heat dissipation due to integrated pumping device and optimized seat / seal face design.
Seal DF-SA Recommended applications
- Power plant technology
- Boiler feed pumps
