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.
