VFD for water well pumps

The SubCon VFD monitors water pressure continuously and the drive will automatically adjust the pump speed to maintain a constant pressure. 

SJE-Rhombus’ VFD incorporates an alpha-numeric display featuring current pressure in PSI, target pressure setting, pump speed (Hz), pump amps, pump run time and error codes. Advanced protection features include adjustable electronic motor overload protection, over temperature (VFD), high and low discharge pressure alarms, and pressure transducer fault.

The SubCon VFD is available for 1.5 HP and 3.0 HP 230V applications and is supplied in a NEMA 1 enclosure with a 4-20 mA (0-145 PSI) pressure transducer. Two SubCon VFDs can be configured for duplex applications where the units will automatically alternate and provide lead/lag control.
