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.
