Speroni VFF series variable-frequency pump adopts the latest VVVF (variable frequency) AC frequency conversion speed regulation technology combined with pressure sensing technology, through the feedback of real-time pressure value compared with the setting pressure, it can adjust the motor speed, and keep the outlet pressure constant automatically. Features: - Energy-efficient. Compared with the traditional way of water supply, the variable frequency pump can save between 20%-50% energy. Small occupied area, less investment and high efficiency. - Flexible configuration, high degree of automation, complete functions and reliable. - Operation performance is excellent, the average torque and abrasion on the shaft is reduced because of the decline of average speed in one day, and thus the life of pump will be longer. Due to the fact that the VSD ensures soft stop and soft start of the pump, it eliminates water hammer. - Easy installation: it replaces water tower, high water tank and traditional air pressure tank water supply devices. Direct pressurized water supply reduces the secondary pollution of water quality caused by traditional pressure tank water supply device. - The spare parts which come in contact with water are all stainless (304 or 316), which ensures high quality of water.
