Sorry. You did not pass the Groundwater Pumping test this time

Correct
Q: On top of energy-efficient pump operation, how does a frequency drive benefit your installation?
A: It comes with a built-in motor protection
Correct
Q: What could be the consequences of using an undersized pump in a well?
A: he pump may not be able to deliver the required
Correct
Q: What kind of riser pipe is most likely to keep itself free from scaling?
A: Flex hoses
Correct
Q: What may cause friction loss in the pipes?
A: Scaling
Correct
Q: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
A: It raises the motor temperature, reducing the lifetime
Correct
Q: By-pass control is an efficient way of performance regulating a pump but what is the downside of the process?
A: Energy is wasted as the pump continues to run at full speed
Correct
Q: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
Correct
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: The shorter the distance is to the water the less expensive it is to make the borehole and subsequently to pump the water to the surface
