1 Identity-Giving FunctionFunção Identitária
Function class
PumpingFunction ⊑ DesignedFunction
Realized in
PumpingProcess ⊑ PlannedProcess
Reciprocating pumps share the same identity-giving function as all pumps - they are designed to realize fluid pumping. The differentia is not functional but mechanical (reciprocating displacement mechanism). The PumpingFunction is already established in the enriched 'pump' class.
2 Genus DeterminationDeterminação do Gênero
Pumpbfo:Object (BFO_0000030)
All sources consistently identify reciprocating pump as a subtype of pump or positive displacement pump. The enriched 'pump' class exists in our ontology with PumpingFunction and Assembly genus. This is the most specific appropriate superclass, more specific than 'Assembly' or 'MaterialArtifact', and enables inheritance of the PumpingFunction.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.ReciprocatingDisplacementMechanism ⊓ ∃hasComponentPartAtAllTimes.PistonOrPlunger ⊓ ∃hasComponentPartAtAllTimes.CylindricalChamber

Contains a reciprocating displacement mechanism with pistons or plungers that move back and forth within cylindrical chambers to displace fluid.

The defining characteristic across all sources is the reciprocating motion of pistons or plungers within cylindrical spaces. This mechanical configuration differentiates reciprocating pumps from all other pump types. The reciprocating mechanism, piston/plunger elements, and cylindrical chamber are the minimal necessary structural components that distinguish this pump type.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts constitute the essential mechanism for reciprocating positive displacement pumping. The reciprocating motion of pistons/plungers within cylinders, combined with intake/discharge valves, creates the positive displacement pumping action that defines this pump type.

InputsEntradas

OutputsSaídas
{'type': 'FluidPortion', 'count': 1, 'constraints': 'same fluid at elevated pressure and discharge conditions'}
TransformationTransformação
mechanical energy added to fluid through positive displacement by reciprocating action
Reciprocating pumps perform positive displacement pumping, taking fluid at suction conditions and delivering it at higher pressure through mechanical displacement. The transformation is purely mechanical energy addition without phase change or composition alteration.
Disjoint WithDisjunto com
centrifugal pump gear pump
C1: centrifugal pump, gear pump. These pump types have mutually exclusive displacement mechanisms - reciprocating pistons/plungers vs rotating impellers vs rotating gears vs rotating screws. The mechanical signatures are incompatible.
