Pump selection made easy

Configuring a product before purchasing it, choosing the model, optional accessories and additional features with just a few clicks – this has become a habit in our daily lives. It is now a useful and interesting opportunity, even when the product in question is not a car, or an item of clothing, but a building product such as a pump to be installed in a system or inserted in a design.

In that context, Calpeda has developed its pump selector software to put consulting engineers and other specifiers at the hub of pump system design.

It is not a question of doing the system design or of replacing the advice of the company’s technical team. It is more a question of offering a tool that allows individuals to autonomously find the most suitable pump for specific projects and particular applications.

The advantages are evident, starting from time management. The pump selector is available 24 hours a day, so users can configure easily from their own personal device, gaining immediate access to all the necessary information.

How does it work?

The starting point when selecting the ideal pump for a given application is the hydraulic characteristics, in other words the flow rate and the head. After indicating where the pump is to be used, the pump selector chooses the models that are best suited to the required performance. Each pump has its own individual characteristic curve, namely a graphic representation of the relationship between the flow rate and the head.

An important consideration is that the curve created by the Calpeda Pump Selector considers hydraulic performance, so it is much more specific than the curves published in the catalogue.

The configurator also makes pre-selection possible. In addition to flow rate and head, users can indicate the application field, the pump family, the frequency and motor phases, and the pump body material, all of which helps reduce the list of selectable models.

Selection and customisation

The step after selection is model personalisation. The configurator allows users to modify a series of elements, updating the pump curve accordingly if performance progress is influenced. If, for example, the pump is estimated to be oversize, the impeller diameter can be decreased, so containing energy consumption and associated costs.

The impeller and shaft material can be chosen according to the application and type of fluid to be moved by the pump. The type of mechanical seal can also be personalised, and a higher IP rating than the standard one can be evaluated.

Clients can choose the voltage, and the pump selector calculates the motor current to allow correct sizing of switchgear.

In addition, the motor winding can be tropicalised so as to make it more suitable for use with an inverter. This treatment, which is standard for pumps of a certain power, is also available for smaller pumps on request.

Having been guided through the pump selection process, the result is the ideal configured pump, together with its technical data sheet (in Pdf format and downloadable) and the related 2D and 3D drawings.
