The Aquavar SPD from Goulds Water Technology – a Xylem brand is a variable-speed drive for single-pump booster applications. It is configured for submersible groundwater and surface motor characteristics, so programming setup takes less than 10 minutes. It can be used for either three- or single-phase input, and has a prewired pressure transducer and a hand/auto option that enables the drive to run at full speed for longer periods of time. The cycle-on time can be configured to a 5 psi system pressure drop or 20 psi system pressure drop. Dual-system set pressure allows the configuration of a timer for multiple set pressure configurations, 70 psi setting for domestic use and 40 psi for irrigation overnight use. 866/325-4210; www.goulds.com.
