Abstract

PURPOSE: To provide possibility of coupling a pair of pumps either in series or parallel by furnishing a pair of opening/closing valves connected to the discharge pipe of one of the pumps and another opening/closing valve connected to the suction pipe of the other pump.
CONSTITUTION: When No.1 opening/closing valve 10 and suction valve 13 are closed and No.2 opening/closing valve 11 is opened and, then, the operation switch of a motor 16 is set on, No.1 and No.2 pumps 2, 6 are put into operation. In this case, pressure of the water discharged from No.1 pump 2 is boosted at No.2 pump 6 and the water is exhausted out of a faucet. When, on the other hand, No.1 opening/ closing valve 10 and the suction valve 13 are opened and No.2 opening/closing valve 11 is closed and, then, the operation switch of the motor 16 is set on, No.1 and No.2 pumps 2, 6 are put into operation, so that combined amount of water is exhausted out of the faucet.
