There is no negative pressure water supply equipment or variable frequency constant pressure water supply equipment.
Non-negative pressure water supply equipment, also known as superimposed pressure water supply equipment, uses tap water as the water source and makes full use of the pressure of the water pipe network from the tap itself to obtain continuous pressure. method of water supply according to which “whatever the difference, make up the amount”.
The variable frequency constant pressure water supply equipment can automatically change the speed of the water pump to keep the water pressure constant to meet the water needs, and obtain constant water outlet pressure and variable water supply to achieve the saving target. water and electricity.
