How to use the hydraulic quicksearch feature?

The hydraulic quicksearch menu allows product filtering and selection based on a user specified duty point. It is located in the top right corner of the Select 5 homepage (fig.1).

Step 1: Set a duty point by entering values for flow [Q] and head [H]. The units are specified by the current unit configuration.

Step 2: Select a mains frequency [50Hz or 60Hz] from the small drop-down menu.

Step 3: Make a selection by placing green checkmarks on desired products (fig.2).

Step 4: Press the mangnifying glass icon in the top right corner to add the selection to your project (fig.2).

Step 5: It may be the case that your selection includes pumps with different circuit types. A window will appear where the circuit type can be specified (fig.3). All products which are marked red, will be excluded from the selection. Press [Ok] to proceed with the project.

Why do I get no results for certain products in the product search?

With the product search, it is possible to search for and select specific products by name and article number. Using this option when searching for older products however may lead to no results being displayed (fig.1). When this is the case, use the out phased pumps search (fig.2). Both the product search and the out phased pumps search have identical functionality, but one is tailored specifically to the selection of older products.

In our example, we search for products of the "TOP-S" series and we get multiple results with the out phased pumps search (fig.3).

How to display a life cycle cost graph for my selection?

The operating costs menu will be availble, once a pump selection has been made and a duty point specified. We recommend using the hydraulic pump selection or the hydraulic quick search for this use case (fig.1).

In our example, we use the hydraulic pump selection:

Step 1: Enter a duty point for a selected series of pumps and press [Next] (fig.2).

Step 2: Click the [Operating costs preview] icon, located in the top left section of the project overview (fig.3). "Please note, this option won't be available immediately after a manual pump selection or product serach.

Step 3: Place checkmarks on products to include them in the life cycle costs graph (fig.4).
