1 Identity-Giving FunctionFunção Identitária
Function class
PumpingFunction ⊑ DesignedFunction
Realized in
PumpingProcess ⊑ PlannedProcess
Diaphragm pumps share the same identity-giving function as other pumps - to move fluids by adding energy. The diaphragm mechanism is how this function is realized, not a different function class.
2 Genus DeterminationDeterminação do Gênero
reciprocating pumpbfo:Object (BFO_0000030)
Both definitions explicitly state that diaphragm pump is a subtype of reciprocating pump. This is the most specific appropriate superclass from the parent candidates list and it is already enriched in our ontology.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.FlexibleDiaphragm ⊓ ∃participatesIn.DiaphragmSealing

Uses flexible diaphragms for both pumping action and sealing to prevent leakage to atmosphere

The definitions emphasize two key features: (1) the use of thin flexible diaphragms as the reciprocating element, and (2) the sealing function that prevents leakage to atmosphere. These are structural differentiating features not present in other reciprocating pump types.

TransformationTransformação
mechanical energy transferred to liquid through diaphragm reciprocation with atmospheric sealing
Diaphragm pumps are specifically designed for small capacity liquid pumping with emphasis on preventing leakage to atmosphere, making them suitable for hazardous or precise metering applications.
Disjoint WithDisjunto com
centrifugal pump gear pump
C4: gear pump. C?: centrifugal pump [kind_ambiguous]. Disjoint from centrifugal pumps due to incompatible mechanisms (reciprocating vs rotary), and from other positive displacement types that use different sealing and displacement mechanisms.
