SJE-Rhombus VARIOspeed® 3R Simplex Control Panel Description
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.
