Abstract

PURPOSE: To enable to select pumps to be used at the time when operation of main pumps is stopped and to select pumps to be used according to a required water flow rate, by employing such an arrangement that a water reserving tank capable of feeding water at the time when the demanded water flow rate is extremely low is disposed in parallel with pumps and has a water feeding function.
CONSTITUTION: A water reserving tank 4 is connected in parallel with the outlet system in which outlets of pumps P1, P2,...Pn are disposed in parallel with each other, and it is arranged to be capable of reserving water during the while when the pumps are in aperation and feeding water when operation of the pumps is interrupted. With such an arrangement, the tank is imprated with a function of feeding water at an extremely low flow rate while operation of the pumps is interrupted, and it is enabled to select a main pump to be used when operation of pumps is interrupted and to operate main pumps alternately. That is, by obtaining an output signal of mian-pump selecting ciruit 2' and a flow-rate signal from a flow-rate indicating output singal of a flow detector QP, use of main pumps P1, P2, in particular, can be selected according to a demanded water flow.
