Abstract
PURPOSE:To stop the circulation of the wasteful water and improve the pump operation efficiency by normally opening a circulating current hole from a water reservoir chamber to an impeller chamber or a water passing hole on the partition wall in a discharge chamber to the water reservoir chamber and closing it during the water feed operation of a pump. CONSTITUTION:A solenoid valve 30 opening or closing a circulating current hole 12 communicated from a water reservoir chamber 8 below a partition plate 5 to an impeller chamber 15 is provided. A flow meter is provided at a discharge joint section, the sensor detects the flow when a pump is operated to feed a fixed quantity of water, and the circulating current hole 12 is closed by a valve body 32. The circulating current of part of the water flowing through the water reservoir chamber 8-impeller chamber 15-water separating chamberdischarge chamber-water reservoir chamber 8 is eliminated, thus that energy is used as the water feed energy, and the pump efficiency is increased.
