IfcPumpType

Definition from IAI: The element type IfcPumpType defines a list of commonly shared property set definitions of a pump and an optional set of product representations. It is used to define a pump specification (i.e. the specific product information, that is common to all occurrences of that product type).

> NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A pump type is used to define the common properties of a pump that may be applied to many occurrences of that type. A pump is a device which imparts mechanical work on a liquid. A typical use of a pump is to circulate chilled water or heating hot water in a building services distribution system. Pump types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

The occurrences of the IfcPumpType are represented by instances of IfcFlowMovingDevice or its subtypes.
