PumP handbook

60 hz

Welcome to Grindex Pump handbook!

With this handbook we want to share some of our wide experience in pumping with sub-mersible pumps. You will find an overview of all Grindex pumps with technical details and a pump school, intended to help pump users with common matters in pumping with sub-mersible pumps. The handbook also contains more sophisticated technical information, like pH tables and graphs that show friction losses in pipes and hoses.

We are sure you will find this handbook useful. This handbook is also available for download from our website, www.grindex.com/us. If you need more copies, please contact Grindex.
