Description (English)

VFD in NEMA 3R enclosure

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

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

It features a variable frequency drive and display in a NEMA 3R enclosure.  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.  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.


Description (Español)

Variador de frecuencia en gabinete NEMA 3R

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

Cuenta con un variador de frecuencia y pantalla dentro de un gabinete NEMA 3R (uso en exteriores).

A medida que las condiciones de flujo cambian en el sistema de bombeo, el VFD es capaz de controlar automáticamente la velocidad de la bomba y mantener una presión de descarga 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.
