DIGITAL CUSTOMIZATION Thanks to digital technology, this pump can be quickly adapted to the customer's system This is done by parametrizing the firmware of the motor at KNF. KNF reserves the right to make technical changes without notice. KNF 01/2024. www.knf.com The performance values for the series models shown on this data sheet were determined under test conditions. The actual performance values may differ and depend in particular on the usage conditions and therefore on the specific application, on the parameters of the components involved in the user’s system and on any technical modifications...
