Abstract

PURPOSE: To make it easy to operate and render the size small by providing a suction opening in the vicinity of the side edge portion of a pressure tank in the direction to have an acute angle with respect to the center line of a shaft of a motor and making an arrangement so that the extension of the center line of the suction opening may pass in the vicinity of the gravity center of a pump.
CONSTITUTION: A suction opening 10 opens in a direction to have an acute angle α with respect to the center line 14 of the shaft of a motor and the opening is in the direction of the normal line of a pressure tank 2. As a consequence, a suction coupling 18 is made short and the size of the pressure tank 2 is made small. Further, the extension of a center line of the suction opening 10 is i the vicinity of the center of gravity (G) of a pump portion 4 on the pressure tank 2. As a consequence, the stability of the pump is improved because only a small beding movement is applied even if the piping weight is applied onto the pump portion. In addition, since the direction of the suction opening 10 is shifted by an acute angle α, the piping does not become an obstacle in mounting or dismounting the casing cover or the like and thus it becomes possible to enhance the efficiency of piping arrangement operation
