VARIOspeed® LCD

5HP - 150HP Constant Pressure Applications

Variable Frequency Drive for pressure control applications.

The VARIOspeed® LCD Drive has been factory pre-programmed for specific pressure control applications. 

As flow and head conditions change in the pumping system, the VARIOspeed® LCD Drive is able to automatically control 
the pump speed and maintain a constant discharge pressure. The desired set pressure is set on the VFD keypad. The pressure transducer measures the pump discharge pressure. 

 

 

VARIOspeed® LCD

Para Aplicaciones de Presión Constante de 5HP - 150HP

El VARIOspeed® LCD Drive (VFD) ha sido pre programado de fábrica para aplicaciones específicas de control de presión. A medida que las condiciones de flujo y de cabeza cambian en el sistema de bombeo, el VARIOspeed® LCD Drive puede controlar automáticamente la velocidad de la bomba y mantener una presión de descarga constante. La presión de operación deseada se ajusta en el teclado del VFD. El transductor de presión mide la presión de descarga de la bomba.

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