Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In coastal areas
Correct
05.
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
06.
Q: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
Correct
07.
Q: How is it possible to protect the motor against bad power supply?
A: By means of an electronic motor protection that senses all possible deviations
Correct
08.
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
