A.6.H:5.1 - Assembled pump

Source sentence: “After seal replacement, the assembled pump remains an integral whole.”

  1. The subject is PumpUnit-37, not the maintenance record, drawing, or seal-replacement Work.
  2. The pump’s direct identity rule decides whether the same individual continued.
  3. The current use names the pump boundary, impeller, casing, replacement seal, and the exact assembly or parthood relations on which operation depends.
  4. If the decision consumes one selected organization of those relations, A.22 governs that structure; if it consumes a construction account, C.13 reports already recovered facts.
  5. A.1 recognizes the candidate whole; B.2 opens only if the replacement leaves a genuine whole-reidentification question.
  6. For calibration, seal replacement, and inspection, identify any actual Work under A.15.1 and state any claimed change separately under the rule for the changed object.
