The flow stays the same; what you pay for in power is height. That is why it is worth working out the head carefully. Choosing the 52 m model instead of the 62 m one, if 52 m is enough, means a motor 1.5 kW smaller, and lower power bills for as long as the pump runs.
If you are not sure which step you need, send us the heights and pipe lengths and we will tell you.
