摘要： PROBLEM TO BE SOLVED: To provide a pump deterioration monitor for a liquid supply system that can positively detect the lowering of performance of a pump. SOLUTION: A pump 5 is driven by a motor 5M to feed water in a water receiving tank 1 to a pressure tank 11 through a distributing pipe 6 and a branch pipe 9. Pressure in the distributing pipe 6 is made specified pressure POFF, and water is fed to a consumer at this pressure. A pressure switch 14 outputs a second signal at the pressure POFF and outputs a first signal at the specified lower pressure PON. A pump control panel 15 drives the motor 5M by the first signal and stops the motor 5M by the second signal. When a motor current detected by a current transformer 20 is the specified value or less, a failure predicting unit 21 starts clocking operating time by the first signal and stops clocking by the second signal. The clocked operating time is compared with standard operating time to judge whether the performance of the pump is lowered or not.
