Product Specification :

  • PS – 160 – SPL Single Spring Unbalanced Seal Are single coil spring unbalanced seals, these seals are simple in design & reliable & rugged enough for the most difficult applications.
  • Designated as Single Spring Unbalanced Seal for 'O' Rings & 'V' Packing used as Secondary seals respectively.
  • Special notches enhance the required driving torque & hence the seal is independent of direction of rotation. Non-clogging spring design enables these seals to be reliably used in situations involving abrasive, corrosive & viscous fluids generally handled by high Temperature pumps.
