1 Identity-Giving FunctionFunção Identitária
Function class
PumpingFunction ⊑ DesignedFunction
Realized in
PumpingProcess ⊑ PlannedProcess
The identity-giving function is pumping - transporting liquid by adding mechanical energy. This is the same function shared by all pump types including centrifugal pumps already in the ontology.
2 Genus DeterminationDeterminação do Gênero
Pumpbfo:Object (BFO_0000030)
Pump is the most specific appropriate superclass from the parent_candidates and is already enriched in our ontology. It provides the PumpingFunction and Assembly structure that positive displacement pumps inherit. More specific than the generic Assembly but captures the essential pumping identity.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.DisplacementMechanism ⊓ ∃participatesIn.PositiveDisplacementProcess

Distinguished from other pumps by having a displacement mechanism that operates through positive displacement principle with fixed displacement volume per cycle.

The differentia focuses on the displacement mechanism and positive displacement operating principle which creates fixed displacement volume per cycle, distinguishing it from dynamic pumps like centrifugal pumps.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

The displacement mechanism is the key differentiating part that enables the positive displacement operating principle. The pump casing is inherited but still necessary.

mechanical energy added to liquid through positive displacement mechanism with fixed volume per cycle
Same basic pumping signature as other pumps but with the specific transformation mechanism being positive displacement rather than dynamic principles.
