VARIOspeed® 3R Duplex

International Product

Description (English)

The VARIOspeed® 3R duplex controller is designed to control (2) three phase pumps in constant pressure control applications including booster pump, deep well submersible pump, and irrigation pump applications. As flow and head conditions change in the pumping system, the VFD is able to automatically control the pump speed and maintain a constant discharge pressure.

Description (Español)

Dos Variadores de Frecuencia (VFD’s) en Gabinete NEMA 3R

El panel de control VARIOspeed® 3R Dúplex controla dos bombas trifásicas en aplicaciones de control de presión constante.

El panel de control VARIOspeed® 3R Dúplex está diseñado para controlar dos bombas trifásicas en aplicaciones de control de presión constante, incluyendo bombas de refuerzo de presión, bombas sumergibles de pozos profundos y en aplicaciones de riego.

Cuenta con dos VFD’s y una pantalla LCD fácil de utilizar dentro de un gabinete NEMA 3R. A medida que las condiciones de flujo y de cabeza cambian en el sistema de bombeo, los VFD’s son capaces de controlar automáticamente la velocidad de la bomba y mantener una presión constante. La presión de operación deseada y los demás parámetros de funcionamiento del sistema se ajustan en la pantalla LCD dentro del gabinete. El transductor de presión mide la presión de descarga de la bomba.
