Correct
Q: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
Correct
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: The well driller can try to run the pump at its maximum capacity in short periods of time over a couple of days
Correct
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
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: 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 could be the consequences of using an undersized pump in a well?
A: The pump may not be able to deliver the required capacity
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: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In coastal areas
