7.5.4.84 Pset_PumpTypeCommon

7.5.4.84.1 Semantic definition

Common attributes of a pump type.

7.5.4.84.2 Applicable entities

7.5.4.84.3 Properties

Name Property Type Data Type Description
Reference IfcPropertySingleValue IfcIdentifier

Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.

Status IfcPropertyEnumeratedValue PEnum_ElementStatus

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).

FlowRateRange IfcPropertyBoundedValue IfcMassFlowRateMeasure

Allowable range of volume of fluid being pumped against the resistance specified.

FlowResistanceRange IfcPropertyBoundedValue IfcPressureMeasure

Allowable range of frictional resistance against which the fluid is being pumped.

ConnectionSize IfcPropertySingleValue IfcPositiveLengthMeasure

The connection size of the object.

The connection to and from the pump.

TemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

Allowable maximum and minimum temperature.

Allowable operational range of the fluid temperature.

NetPositiveSuctionHead IfcPropertySingleValue IfcPressureMeasure

Minimum liquid pressure at the pump inlet to prevent cavitation.

NominalRotationSpeed IfcPropertySingleValue IfcRotationalFrequencyMeasure

Rotational speed of the object under nominal conditions.

Pump rotational speed under nominal conditions.
