LORENTZ PS 9k2 C-SJ8-44 Submersible Pump System

The LORENTZ PS 9k2 C-SJ8-44 Submersible Pump System are our next generation of solar water pumps designed to deliver the higher volume of water in a wide range of heights. The PSK2 pumps operate equally well in projects of irrigation and drinking water applications where wide area reliably meet the most demanding requirements, economically and without the use of fossil fuels or network connection.

PSK2 provides all the features and functions that water projects require larger scale including a wide range of sensor inputs and built-in monitoring and management. PSK2 also supports LORENTZ CONNECTED services for cost-effective remote monitoring and management. Although technically advanced, PSK2 is simple to specify, install and maintain and offers outstanding performance driven by the long experience of LORENTZ solar pumping out of network.
