Product Name:WP9-VF series Multiple pump control
Category:Frequency Inverter
 The main characteristic of the WP9 multiple pump Frequency Inverter is the control of two or more pumps in parallel using only one frequency inverter. The inverter selects which pumps will operate in order to keep/control the process value of the pumping system. An alternation between their activation is also performed, making it possible an equal use of the pumps.
