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: 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: 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: 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: Why is it important to know the water drawdown?
A: The more the drawdown increases during pump operation, the more pressure is required to lift the groundwater to the surface
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: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
