 %SUMMARY Pump Ideal pump component for compressible flow
+
+%DESCRIPTION Pump represents an ideal pumping component for compressible
+%DESCRIPTION or incompressible flow though a pipe, it may also be used as a turbine.
+%DESCRIPTION The pump is ideal in the sense that the mass flow rate
+%DESCRIPTION depends only on the shaft speed.
+
 %DESCRIPTION Parameter 1: c_v - specific heat of fluid
 %DESCRIPTION Parameter 2: Parameter passed to Density component
 %DESCRIPTION Parameter 3: alpha = (n-1)/n, n coefficient of polytropic
 %DESCRIPTION expansion.
 %DESCRIPTION Parameter 4: k_p pump constant: mass flow = k_p*shaft speed
