Constant pressure pump control for variable demand irrigation - Water & Wastewater - Irrigation
The CSV has state of the art technology, designed to mimic the “constant pressure” control of Variable Frequency Drive VFD, or “so called” constant pressure pumps. Requiring no electronics, and therefore using no extra power, the CSV eliminates the problems long associated with VFD control.
The pressure controlled CSV reacts extremely fast to changes in the system demand. This counteracts negative and positive transient pressure waves, by cancelling them out with an equal and opposite pressure wave. Eliminating transient pressure waves, and the subsequent water hammer they cause, can conserve vast amounts of water and energy. Eliminating water hammer also helps keep the pipe in the ground and eliminates expensive repairs.
