VARIOspeed® 3R Control Panel

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.
