VFPD series variable frequency pump system adopts the latest VVVF(variable voltage and 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.
1. High efficiency and energy saving. Compared with the traditional way of water supply, it saves the energy by 30%-60%． 2. Smaller occupied area, less investment and higher effciency. 3. Flexible configuration, high degree of automation, complete functions, flexible and reliable. 4. Operation performance is reasonable as the average torque and abrasion on the shaft is reduced because of the decline for average rotation speed in one day，which makes the life of pump longer． 5. Because it can realize the soft stop and soft start of water pump, it can eliminate water hammer effect.(water hammer effect means when direct starting and stopping happens, liquid kinetic energy changes sharply, which leads to the great impact of the network and great change causes .) 6. Easy installation. it replaces water tower, upper water tank and traditional air pressure tank water supply device. 7. Direct pressurized water supply reduces the secondary pollution of water quality caused by traditional pressure tank water supply device. 8.The wetted spare parts are all stainless steel (304 or 316).
1. Liquld temperature: normal temperature model (0℃-50℃）／high temperature model(O℃-90℃） 2. Environment temperature：≤50℃． 3.Factory pressure setting:2.0bar 4.Specification of pressure tank:2L 5.Pressure filled in tank:2.0bar
Various types of water factory, booster station, hotel, residential areas etc.
we do not match the value of system working pressuring and precharge prssure of the tank, and please do it before using. When the user sets the system working pressure, please then adjust the pressure of the tank accordingly. Usually speaking, the value of precharge pressure of the tank is 50%-70% of the system working pressure.
