Submersible pumps are generally used. But the water in the pool needs to be deep enough.

If the water level is shallow, use a circulation pump. The circulation pump is generally installed in the machine room.

If the injection is required to be higher, the nozzle is designed to be gradually smaller.

Some fountains spray water column sometimes high and sometimes low,which is due to the installation of the frequency converter. Adjust the water column height through the inverter. There are also valves such as ball valveson the nozzle to adjust the amount of water.
