Descriptions and Features
The F&W Artesian Drive is a dependable water system
Variable Frequency Drive (VFD) that uses custom program-
ming to enhance the performance of standard centrifugal
pumps. When applied correctly to three phase motor driven
pumps, the Artesian Drive eliminates pressure cycling associat-
ed with conventional pressure switch controlled water pump-
ing systems and provides a constant output pressure.
KEY FEATURES OF THE ARTESIAN DRIVE INCLUDE:
• Constant water pressure with a wide range of settings
(30-80 psi) (Note: The maximum obtainable system pres-
sure is limited by the performance of the pump installed)
• Smaller pressure tank can be used
• Fits the pump to the application – pump speed is con-
trolled to provide the optimum performance without
overloading the motor
• Flexibility – you can use this unit with standard off-the-
shelf pumps and 3-Phase motors
• No in-rush (power-on transient) current
• Low motor start-up current (soft-starting)
• Active Power Factor Correction minimizes input RMS cur-
• Protection features
- Dry run conditions – using intelligent load monitor-
ing (see Page 8)
- Bound pump – with auto-reversing torque
- High voltage / lightning surge
- Low line voltage
- Short circuit
When unpacking the unit, inspect carefully for any damage
that may have occurred during transit.
