Q: What should the minimum flow past the motor be to ensure sufficient motor cooling?
A: 0,15 m/s
Q: What should the minimum flow past the motor be to ensure sufficient motor cooling?
A: There are no specific requirements
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In forests with old trees
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In coastal areas
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In elevations above 1000 m
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: 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 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: 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: 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 may cause friction loss in the pipes?
A: Scaling
Q: What may cause friction loss in the pipes?
A: Poor water quality
Q: What may cause friction loss in the pipes?
A: High water temperature
