Variable speed electronic pump for filtering swimming pool water containing chlorine or salt or for use in fish farms. Equipped with a display, variable frequency drive and integrated pre-filter (inspectionable). Designed for medium-large and large swimming pools in residential building service and commercial building service. The display with push-button panel allows you to easily set the operating modes according to the time of day, the day of the week and the season. Operation with speed or flow control for greater adaptability to different installations. Thanks to the variable frequency drive, you can save energy. The permanent magnet motor is cooled by the pumped liquid. The absence of cooling fans allows the pump to be installed even in tight spaces with little air circulation and makes it quieter than pumps with fans. Equipped with connector for remote control. Lid with screw. The Epro SVRS version is equipped with a software function that disables pump suction if an obstruction is detected. SVRS means Safety Vacuum Release Systems. The 12-pin control board makes the pumps compatible with any control panel, whether analog (0 - 10 V and 4-20 mA) or digital.
