SJE-Rhombus VARIOspeed® 3RD Duplex Control Panel Description

The VARIOspeed® 3R Control Panel is designed to control (2) three phase pump 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 VFDs 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 panel. The pressure transducer measures the pump discharge pressure.

Not for use with sewage pumps.
