Drip/Micro Spray

Drip and micro-spray irrigation are for low pressure applications, where there is a requirement for reducing potential evaporation and run off as much as possible. Keeping the pressure constant is vital for ensuring uniform application throughout each zone in the system, and this can be the most energy-efficient method of irrigation, if managed properly. Achieving this requires that the system can compensate for the variations in flow to ensure constant pressure, as zones cut in and out.

A variable speed pump ensures constant pressure in the zones, while keeping operating costs down at the same time. The pump control connected to Grundfos pumps can also monitor the pump data, and this can be used to detect when the sand filter needs cleaning. In precision irrigation systems, Grundfos can also integrate chemical injection equipment that ensures a uniform mix in the line.
