FEATURES

  • Applicable for suction and delivery (discharge).
  • Provides sound and vibration isolation.
  • Gaskets and packing are not required.
  • Floating flanges allow for easy installation.
  • Prevents piping system and equipment breakdown by absorbing elongation and contraction caused by temperature variances.
  • Absorbs water pulsation and minimizes water hammering.
