Test results
01.
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
01.
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 replace the casing with a new one with smaller slots
01.
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: An additional filter can be installed inside the casing
02.
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
02.
Q: On top of energy-efficient pump operation, how does a frequency drive benefit your installation?
A: It can reduce cavitation
02.
Q: On top of energy-efficient pump operation, how does a frequency drive benefit your installation?
A: It cools the motor
03.
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In forests with old trees
03.
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In coastal areas
03.
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In elevations above 1000 m
04.
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
04.
Q: Why is it important to know the water drawdown?
A: Increased drawdown leads to poor water quality
04.
Q: Why is it important to know the water drawdown?
A: Steel casings may not be used if the drawdown is too big
05.
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
05.
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
05.
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
06.
Q: What kind of riser pipe is most likely to keep itself free from scaling?
A: Plastic hoses
06.
Q: What kind of riser pipe is most likely to keep itself free from scaling?
A: Stainless steel pipes
