VARIOspeed® 3R Duplex Control Panel

VFD in NEMA 3R enclosure

The VARIOspeed® 3R Duplex control panel controls two three phase pump in constant pressure control applications.

The VARIOspeed® 3R Duplex control panel is designed to control two three phase pump in constant pressure control applications including booster pump, deep well submersible pump, and irrigation pump applications.

It features two variable frequency drives (VFD) and display in a NEMA 3R enclosure.  As flow and head conditions change in the pumping system, the variable frequency drives (VFD) are able to automatically control the pump speed and maintain a constant discharge pressure.  The desired set pressure is entered on the display inside the control panel.  The pressure transducer measures the pump discharge pressure. 

Not for use with sewage pumps.

Panel de Control VARIOspeed® 3R Dúplex

Dos VFD 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 y una pantalla LCD fácil de usar 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 se ajusta en la pantalla dentro del gabinete. El transductor de presión mide la presión de descarga de la bomba.

Incluye transductor de presión de 0-200 PSI (4-20 mA)

NO debe utilizarse con bombas de aguas residuales.
