Axiomatization Decision Log

Identity-Giving Function
Function class
PumpingFunction
⊑ DesignedFunction
Realized in
PumpingProcess
⊑ MomentumTransfer
The pumping function is identity-giving for all pumps - it is the designed capability to add mechanical energy to fluid to increase pressure and enable flow. This distinguishes pumps from other fluid handling equipment like valves (which control flow) or heat exchangers (which transfer thermal energy).

Genus Determination
Assembly
bfo:Object (BFO_0000030)
Causally unified material artefact composed of physically connected,
separable MaterialComponent parts. Satisfies
Assembly ⊑ MaterialArtifact ⊑ bfo:Object.
Pumps are complex mechanical devices with multiple physically connected subcomponents (casing, impeller/pistons, shaft, seals, bearings) that can be disassembled for maintenance, but function as a single causally unified object. While 'mechanical equipment class' and 'ProcessEquipment' appear in parent candidates, these are too broad and not ontologically precise. Assembly is the most specific appropriate IOF-Core class since no domain-specific pump superclass is enriched yet.

Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts are fundamental to the pumping function across all pump types, though their specific implementations vary (centrifugal impellers vs pistons vs gears)

Transformation (T)
mechanical energy added to fluid
Pumps transform a single fluid stream by adding mechanical energy to increase pressure, enabling transport and overcome system resistance

Disjointness Axioms
Compressor
Turbine
C2: Compressor, Turbine. Pumps handle liquids for transport; compressors handle gases for compression; turbines extract rather than add energy. These have incompatible process signatures.
Cross-Standard Observations
ISO 15926 and DEXPI emphasize the pumping capability and potential for system integration. CFIHOS provides the clearest functional definition focusing on energy addition/removal. ISO 14224 classifies as rotating equipment, which is constructively accurate for most pumps but not definitionally essential.
