Ingersoll Rand 18NK

Estabrook Service & Repair • Before & After

Our Initial Inspection:

After disassembling and cleaning the pump, our inspection revealed multiple areas needing attention:

  • The ring clearances were over the maximum allowed,

  • The bottom shaft bearing fit was scored, while the top fit was very worn,

  • The suction bell bearing was both scored and oversized,

  • Two of the bowl bearings were overly worn,

  • The thrust top bowl was in disrepair, especially with the OD threads,

  • The rubber spider bearing was worn,

  • The stuffing box bearing was pulled out of the stuffing box, and the stuffing box fit going into the head was loose,

  • The clearance between the pipe and top bowl was too large;


Our Service & Repair Work:

With nearly all components of the pump in poor condition, Estabrook’s Service & Repair Department blast cleaned and replaced all identified parts. Subsequently, our team individually serviced the discharge head, impellers, suction bell, #2 bowl, and the top bowl. We balanced the impeller to the proper ISO specifications, painted the exterior safety blue, and delivered the repaired equipment to the customer.
