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 could be the consequences of using an undersized pump in a well?
A: The pump will give too high pressure
Q: What could be the consequences of using an undersized pump in a well?
A: The risk of cavitation is very high
Q: What could be the consequences of using an undersized pump in a well?
A: he pump may not be able to deliver the required
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 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: 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
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: 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
