• Precise Flow Control Turn the knob or use the push button control for greater control over the discharge flow rate for better accuracy and precision during sampling.
• Wide Performance Range Not just one performance curve, the Grundfos VFD covers a range of performances and can function at any point of operation within that range.
• Choose Input Power Either 120V or 230V, single-phase AC input power is available.
• NEMA 4x Enclosure The NEMA 4x enclosure is designed for outdoor duty and is resistant to damage as a result of incidental exposure to rain. Designed for wash down applications.
• Optimized Volts ⁄Frequency Pattern The Grundfos VFD V/Hz pattern is specially optimized to allow the most efficient operation of the Redi-Flo2® variable performance pump.
• Motor Protection The Grundfos VFD will protect the Redi-Flo2® Variable Performance Pump from adverse motor conditions such as, over- and under-voltage, over-current, and ground fault.
