Successfully maintaining a pump system takes countless man-hours and sizeable investment capital. However, one of the most critical steps in ensuring a pump operates at peak efficiency and performance—pump selection—can now be as easy as the click of a button. Now entering its second decade, VSX–Vogel Software is launching the latest version of its well established pump selection software: Spaix. The software has been successfully used by national and international customers for several years. The new multi-platform concept consisting of desktop-, web- and mobile-version is unique on the market, giving pump users another tool in their quest to match the right pump for the right job.
Spaix 4 Pumps is a high-performance application for the computer-supported selection and configuration of
centrifugal pumps. In addition, the software provides valuable support throughout the entire sales process.
Spaix 4 Pumps is based on a completely new technology which has been tailored specifically to meet the demands of the modern IT landscape. Above all, aspects such as internet security and flexible authorization models played a major role. In addition, the new Version 4 offers existing customers as well as new clients many interesting possibilities to further optimize their pump selection and configuration processes and to adapt to current market conditions.
The user-specific product data that is stored in the database program is linked practically with predefined selection parameters and calculation methods.  As a result, pumps matching the specifications are displayed for the user. For selecting the right pump the users are offered different access points similar to the previous versions, such as hydraulic selection or the product selection browser.
Calculation of operating and life cycle costs: consideration of different load
profiles, graphic and tabular display of the cost comparison.
The hydraulic selection enables the sizing and configuration of pumps as per predefined operating conditions, such as area of application, fluid, flow rate, and head. The Spaix 4 product range supports the selection of several operating points for the first time, even for different fluids. The sizing can be done as a single pump or as a parallel or series connection of several pumps. In addition, the definitions of limits and search guidelines have been simplified, as these can now be compared directly with the product features of individual components. Specifically predefined input templates also make sizing special pump systems easier—for example, pressure booster systems, borehole pumps, or process pumps—without the template being overloaded with entry fields for simple systems.
The product configuration supports the user in selecting available options and is done in several steps, whereby the program independently checks whether the selected pump fulfills all the entered criteria. The pump performance curves are converted automatically to the relevant operating conditions by the software. For high-viscous Newtonian fluids the method according to the latest standards of the Hydraulic Institute (HI) from 2010 is used amongst others.
The program supports all common procedures for adjusting the duty point (impeller trimming, speed adjustment, throttling and many others). The performance curve optimization procedures can also be used for multi-stage pumps. The new feature here is that for the performance curve optimization using affinity laws various methods for depreciating the efficiency are available.
The database maintenance program is a multifaceted software to maintain the complete database
and to influence the functionalities of the selection program.
Spaix 4 Pumps has been considerably expanded and improved for the efficient sizing and dimensioning of special pump systems. The software offers the user a multitude of components, which can be used for the configuration process—for example, materials, shaft sealing, bearing frame, and coupling protection.
Specifically to highlight here are the consideration of motor performance curves, magnet coupling sizing, the treatment of frequency converters as well as the sizing of borehole pumps.  The sizing of booster sets according to DIN 1988 is also newly integrated. For electronically controlled circulating pumps, as are widely used in heating technology, there is a calculation module that calculates the control curves from the constant speed curves. As well as various technical parameters, such as a power control, graphical aspects are also taken into account.
With the optionally expandable functionality of pipe calculations (additional Spaix PipeCalc module), the user also receives support in determining the operating point. On the basis of defined parameters, the program determines the pressure loss for unbranched systems and the pump volume in accordance with common international standards (for sewage and wastewater based on DIN EN 12056). The results are automatically assumed for the pump selection and calculation data sheets are integrated into the current project. For pump manufacturers, it is now even easier to define typical pipe systems with the data maintenance program and considerably speed up the recording of friction loss data by the selection program’s user.
As part of the project management, quotes including detailed datasheets can be compiled and supplied. The price calculator integrated into the program can be flexibly adapted to the requirements of any company. Prices are calculated as per the selected configuration including all components and accessory parts and can be displayed as an overall price or on the basis of single components.
Using dynamic product codes, the configuration is linked with the price table and the item numbers as applicable. As a result, clear identifiers are created, which are also used to integrate external programs, such as ERP systems. In order to be able to manage and supply the prices for different markets Spaix works with user group-specific price groups. Various currencies are supported and it is also possible to convert using the currency exchange rate. With an additional module it is possible to display the product availability through enabling delivery times on the quote.
By using special interfaces project data can be transferred to external programs such as ERP and CRM systems for further editing.
The user management can be organized with even more detail in Spaix 4 Pumps. Program functions, price groups, and product ranges can be managed and released appropriately for different user groups. An expanded user authorization system makes it possible to accurately allocate rights to user groups.
The data maintenance program is a versatile piece of software to maintain the entire database and influence the functions of the selection program. The person creating the data decides which parts of the program are available for which products and which users. The modular concept guarantees a minimum amount of data redundancy and displays different product structures.
In Spaix 4 Pumps the calculation of the energy efficiency index (EEI) and the minimum efficiency index (MEI) is integrated in accordance with the current EU guidelines. Through the ongoing updating of the guidelines companies can react properly on current and future framework conditions in the economic environment.
In addition, Spaix 4 Pumps offers the calculation of operating and life cycle costs whereas various load profiles can be taken into consideration depending on the use. The cost comparison of the various solutions is shown clearly in graphic and tabular format. ■
