Pump

Pump#

The Pump model is a PressureChanger, 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 for details.

Example#

The example below demonstrates the basic Pump model usage:

import pyomo.environ as pyo
from idaes.core import FlowsheetBlock
from idaes.models.unit_models import Pump
from idaes.models.properties import iapws95

m = pyo.ConcreteModel()
m.fs = FlowsheetBlock(dynamic=False)
m.fs.properties = iapws95.Iapws95ParameterBlock()
m.fs.unit = Pump(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)
