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 handy. This handbook is also available for download from our website, www.grindex.com. If you need more copies, please contact Grindex.

Drainage pumps made of stainless steel, INOX
These pumps are designed to meet the tough requirements from mines, construction sites, landfill sites and other applications that deal with corrosive water. One application is in mines where the water becomes caustic and destroys conventional pumps in matter of days. The pumps may also be used in applications where saltwater is pumped, like ship-yards, fish farms, construction works in harbours and offshore projects.
