Product Description
KSB 4EYS Seal NU048M0-4EYS 01888678 Single Mechanical Seal
Mechanical seal according to DIN EN 12756
4EYS
For the Etanorm SYT/Etabloc SYT/Etaline SYT pump type series. Single, unbalanced component seal, dynamic design. Solid primary rings designed to maintain an optimum lubricating film between the seal faces also at high pressures and temperatures. 4EYT variant in tandem arrangement also for use as a double mechanical seal.
Technical Data
Cartridge seal No
Design Dynamic
Balancing Unbalanced mechanical seal
Sealing type Single
Maximum allowable fluid temperature 140 °C
Benefits
- In combination with the pump's design, the seal can be used for fluid temperatures of up to 350 °C. The complete Etanorm SYT application range can thus reliably be covered with this mechanical seal.
- With the multi-spring arrangement the axial spring force is evenly distributed over the entire circumference of the primary ring. This minimises wear and contributes to a long seal life.
- The solid primary ring is designed to maintain an optimum lubricating film between the seal faces also at high pressures and temperatures.
Technical Data
Maximum allowable axial movement 2 mm
Minimum allowable axial movement -2 mm
Component type series KSB Etanorm-SYT [B]
