    Information about: Centrifugal Pump


    For most pumping applications centrifugal pumps are the first choice of engineers. The versatile and simple nature of centrifugal pumps led to the success of this principle that was introduced by Denis Papin in 1689. In today's world many vendors have special designs for specific applications. The selection of a suitable pump is a process in which an engineer first calculates the pumping conditions and then decides which type of pump he wishes to use for his application. After this the search for a suitable pump starts with requisitions, vendor selection and requests for quotations. This is logically followed by evaluation, purchase, delivery and installation of the pump.

    The engineering page is independent of any pump manufacturer. The server side software is developed using an array of literature and other independent data about pump hydraulics. The results are not intended to exclude any products or manufacturers but to aid engineers with their work.

    These results of the calculations will be useful to establish if a centrifugal pump is a suitable option for your pump application and preliminary data that help to further design the installation long before a centrifugal pump is selected. Also the data provide an independent benchmark and if the quotations of vendors significantly differ from the data provided by the engineering page this could be a clear indication of an error. The suction conditions, fluid characteristics and other application data are used to calculate parameters such as the suction specific speed, specific speed, required shaft power, required impeller dimension and volute or diffuser dimensions. A lot of care was put into the prevention of cavitation. In fact one of the complicated parts of the development of the software was to keep the output simple and not reply with a deluge of parameters. We believe the transparent presentation demonstrates that we succeeded in this and that you will find this routine useful.
