Cartridge mechanical seal DF-SA DiamondFace

springpumpmetal

Cartridge design Single seal Balanced Integrated pumping device Stationary spring loaded unit Inserted seal ring Rotating mating ring (DiamondFace coated) Advantages 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. Operating range Shaft diameter: d1* = 120 ... 250 mm (4.72" ... 9.84") Sliding velocity: vg = 70 m/s (330 ft/s) Axial movement: ±3 mm * Other sizes on request Materials Seal face: Composite carbon Seat: SiC DiamondFace coated Secondary seals: EPDM (E), FFKM (K) Springs: CrNiMo steel (G) Metal parts: CrNiMo steel (G) Recommended applications Power plant technology Boiler feed pumps
