INSTRUCTION:

VF series Variable-Frequency Pump 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

 PRODUCTS FEATURES:

1.Energy-efficient. Compared with the traditional way of water supply, the Variable frequency pump can save the energy 30%-60%.

2.Small occupied area , less investment and high efficiency.

3.Flexible configuration, high degree of automation, complete functions, flexible and reliable.

4.Operation performance is reasonable, the average torque and abrasion on the shaft is reduced because of the decline for average speed in one day, the life of pump will be 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 direct starting and stopping ,liquid kinetic energy of a sharp change, lead to the great impact of the network, there is a lot of damage)

6.Easy installation, it replaces water tower, high 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 spare parts which flowed by water is all stainless (304 or 316), which ensure the healthy water .

APPLICATION AREA:

Using for the various types of water factory, booster station, hotel, residential areas etc.

OPERATING CONDITION:

1.Liquid Temperature: Normal Temperature(0℃~+50℃)/High Temperature(0℃~+90℃).

2.Environment Temperature:≤50℃.



Please pay Attention: We have not match the working pressure and pressure filled in the tank.

Please Match the pressure before use it. First the user adjust the pressure, then also needs to adjust 

the corresponding pressure filled in the tank ,which commonly 50%-70%of working pressure.
