How would you rate this course?
1: What is the benefit of a booster pump with variable speed
The pump automatically adjusts to changes in the water consumption to keep energy usage as low as possible
1: What is the benefit of a booster pump with variable speed
A pump with variable speed is less noisy
You can find the answer here >
1: What is the benefit of a booster pump with variable speed
You can easily increase pressure in case of sediment build-up in pipes
You can find the answer here >
2: Why are pressure relief valves not required in an intelligently designed boosting solution?
There is no excessive pressure in the system
2: Why are pressure relief valves not required in an intelligently designed boosting solution?
The booster manifold is made of stainless steel and therefor requires no braze valves
You can find the answer here >
2: Why are pressure relief valves not required in an intelligently designed boosting solution?
As you typically have a break tank, pressure relief valves are not needed

5: What are the benefits of an IE4 motor?
Fitted with a frequency drive the motor can adjust its speed to demand to lower energy consumption and wear
5: What are the benefits of an IE4 motor?
The motor has all-magnetic bearings
You can find the answer here >
5: What are the benefits of an IE4 motor?
The motor has a built-in delta P sensor
