Main technical Parameters:

Flow range: 2m2/h-20m2h
Head: 30m-300m
Optional Configuration:
Vacuum insulated device
Variable-frequency converter
Protecting device for cavitation erosion
Features:

The pump and motor submerged totally in the liquid to reduce lost
Vacuum adiabatic set prevent the liquid from the heat
Special design with no seal set and submerged reduce the chance of maintain
The vertical type makes the motor a better performance and long lifetime
Frequency control of motor enlarges the work range of pump
