The Pump model is a PressureChanger <technical_specs/model_libraries/generic/unit_models/pressure_changer:Pressure Changer>, where the configuration is set so that the "compressor" option can only be True, and the default "thermodynamic_assumption" is "pump." See the PressureChanger documentation <technical_specs/model_libraries/generic/unit_models/pressure_changer:Pressure Changer> for details.
The example below demonstrates the basic Pump model usage:
import pyomo.environ as pyo from idaes.core import FlowsheetBlock from idaes.generic_models.unit_models import Pump from idaes.generic_models.properties import iapws95
m = pyo.ConcreteModel() m.fs = FlowsheetBlock(default={"dynamic": False}) m.fs.properties = iapws95.Iapws95ParameterBlock() m.fs.unit = Pump(default={"property_package": m.fs.properties})
m.fs.unit.inlet.flow_mol[0].fix(100) m.fs.unit.inlet.enth_mol[0].fix(2000) m.fs.unit.inlet.pressure[0].fix(101325)
m.fs.unit.deltaP.fix(100000) m.fs.unit.efficiency_pump.fix(0.8)
