Reciprocating Pump Modelling



Here below the General Arrangement of the reciprocating pump and the pump modelled in Caesar as piping anchored in correspondence of the center line of the pump.



Is this modelling suitable for this type of pump? Or is it mandatory to model the pump as rigid element?

Provided you have accurate dimensions and materials for the pump nozzles and they are uniform wall thickness, modeling those elements as piping should not be a problem.

However, modelling the pump casing as piping can get you into trouble. While it is not obligatory to make it perfectly rigid, the "best" way is to get the stiffness values from the manufacturer.

An alternative would be to model the casing in Nozzle Pro which will calculate stiffness values.
