How much total dynamic head (TDH) can a Sun Mill pump to?
The different Sun Mill models have different capabilities. In general, there is a compromise between the head that is required to be overcome and the amount of water that can be pumped during a period of time. The Aqua is capable of pumping up to 70m (700kPa or 100psi). The Cascade is capable of pumping up to 35m (350kPa or 50psi). The Sun Mill Original is capable of pumping up to 60m (600kPa or 87psi). The Quicksilver and Jetstream are capable of pumping up to 120m (1200kPa or 175psi). Larger Rapid systems are capable of pumping up to 230m (600kPa or 330psi). In practice, you are not limited by the amount of TDH you need to overcome. To pump higher heads, multiple Sun Mills can be daisy-chained together.
