The Mono Pumps Sun-Ray solar pump has been designed to transfer surface water with the same efficiency and reliability as other Mono solar pumps. Available, with either a stationary or GPS Tracking array, ranging from 150 Watts to 1575 Watts, the Sun-Ray can deliver very high daily flows with discharge pressures of 120m. The highly efficient, helical rotor pump is inherently self-priming, so the pump can be positioned up to 6m above the water source, allowing the pump to be installed on the top of dam walls or on river-banks above the high water mark. The Sun-Ray is suitable to pump water from springs, rivers, tanks and dams. It is available with a floating pontoon that has been designed to safely enable the pump to float on a dam or other water source.
