Repair and maintenance of your existing pump system
Naturally, you can always call on Grundfos for the repair and maintenance of pumps you have purchased from us. Grundfos can repair your pumps to the same specifications as new. However, it is important to remember that an upgrade or even a replacement pump can be cheaper than repair in the long term. See "Upgrades and Replacement" for how this makes good business sense.

The purpose of CAPS is to provide a complete tool that contains both an extensive catalogue of Grundfos products and a sizing program to select the most suitable pump for your application.

Last but not least, the software contains the instruction and operating manuals for nearly all Grundfos pumps in multiple languages. Service drawings, exploded views and parts lists are available for all sewage products as well as several other pump types.
