Pump

The Pump model is a :ref:`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 :ref:`PressureChanger documentation <technical_specs/model_libraries/generic/unit_models/pressure_changer:Pressure Changer>` for details.

Example

The example below demonstrates the basic Pump model usage:

.. testcode::

  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)
