In A Water Distribution System Drive technology matures to conquer pressure and leakage problems while increasing pump life and saving energy. They cost less than water towers, offer precise pressure control, reduce water leakage, increase pump life and save energy. Mechanical devices such as control valves are used to regulate pressure. These methods have disadvantages when it comes to operation, flexibility and energy consumption.
Water towers can be an expensive choice when it comes to maintenance and system upgrades.
Selecting the wrong control valves can significantly reduce pump efficiencies and could lead to routine maintenance problems. With the proper design, VFD technology offers solutions to these problems. A VFD is an electronic controller that adjusts the speed of an electric motor by modulating the power being delivered. VFD and pump combinations maintain a constant pressure in the system by taking 4-20 mA signal from a pressure transmitter and adjusting motor output according to the feedback requirements. VFDs overcome the disadvantages of traditional methods mentioned earlier and offer many benefits-increased pump life, precise pressure control, reduced water leakage, easy upgradability and energy savings.
