The Star Pump Alliance (SPA) is a joint initiative of leading pump manufacturers to support pump users in the search and selection of suitable pumps and manufacturers for their industrial application. The alliance of companies means that almost all common applications can be covered. This means users always have access to at least one manufacturer with the right pump technology, saving them a lot of time. At the same time, from the website visitor's point of view, the SPA is a comprehensive information platform for the professional pump user, reporting on technologies, industries, case studies, news, etc., and featuring a hitherto unique cross-manufacturer technology selector that recommends possible suitable pump technologies based on the application parameters entered and enables easy contact with the manufacturer. It also offers some useful converting and calculating tools, etc.
