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: 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: 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
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
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
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 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: The pump may not be able to deliver the required capacity
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: 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
Q: How is it possible to protect the motor against bad power supply?
A: By means of a UC filter
Q: How is it possible to protect the motor against bad power supply?
A: By using a special water resistant cabling
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
