Artesian Drive^® is a line of custom-programmed Variable Frequency Drives (VFD) that enhance the performance of standard centrifugal pumps. When applied correctly to 3 Ph motor-driven pumps, the Artesian Drive^® eliminates pressure-cycling associated with conventional pressure-switch-controlled water pumping systems and provides a constant output pressure by increasing or decreasing motor speed, based upon demand.

Artesian Drive^® is factory-programmed for F&W centrifugal pumps to provide optimum performance and motor protection. The Artesian Drive^® can be used with other pump brands, provided the pump is powered by a 3 Ph motor that does not exceed the maximum current output rating of the drive.

• Pre-programmed drives: no need for field technician to program the drive at the site
• Drives are available for centrifugal pumps powered by a 3 Ph motor
• Constant water pressure with a wide range of settings (15-95 PSI)*
• Pressure is easily adjusted with a 7/32” (5.6 mm) allen wrench
• Works with a small pressure tank or larger tank, already in place
• No in-rush current at start-up
• Soft start reduces mechanical/electrical stress, prolonging pump and motor life

Built-in protection and diagnostics:

• Low line voltage
• Short circuit
• High voltage/lightning protection
• Dry run conditions, using intelligent load monitoring
• Overheated drive with automatic reset

Included items:

• Factory-programmed variable speed drive unit
• NEMA 4 enclosure
• Pressure sensor, preset at 50 PSI
• Sensor adjustment tool
• 10' (3 m) sensor cable

Notes

The maximum obtainable system pressure is limited by the performance of the pump installed.
