Test results
Q: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
A: It increases speed and thereby the performance of the pump
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
Q: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
A: It reduces flow and pressure
Q: By-pass control is an efficient way of performance regulating a pump but what is the downside of the process?
A: The by-passed water is wasted and cannot be used again
Q: By-pass control is an efficient way of performance regulating a pump but what is the downside of the process?
A: The motor temperature rises and increases the risk of motor burn-out
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
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
Q: Why is it important to know the water drawdown?
A: Increased drawdown leads to poor water quality
Q: Why is it important to know the water drawdown?
A: Steel casings may not be used if the drawdown is too big
Q: What kind of riser pipe is most likely to keep itself free from scaling?
A: Plastic hoses
Q: What kind of riser pipe is most likely to keep itself free from scaling?
A: Stainless steel pipes
Q: What kind of riser pipe is most likely to keep itself free from scaling?
A: Flex hoses
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
Q: On top of energy-efficient pump operation, how does a frequency drive benefit your installation?
A: It can reduce cavitation
Q: On top of energy-efficient pump operation, how does a frequency drive benefit your installation?
A: It cools the motor
Q: What is the most effective way to stay updated on your pump’s condition?
A: Manual inspection
Q: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
Q: What is the most effective way to stay updated on your pump’s condition?
A: Regular maintenance
Q: What is well development?
A: The drilling of a hole in the ground to find groundwater
Q: What is well development?
A: The installation of the well casing in the centre of the borehole
Q: What is well development?
A: A process that ensures that the well’s sand filter has been improved so the well produces clean, sand-free water
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
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 from the surface to the ground water, the better the water quality is
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: A higher level means lower water temperatures and better motor cooling
