A control box that communicates with the discharge side and suction side of the electric pump, a diaphragm installed in the control box that charges the inside of the control box into the discharge side chamber and the suction side chamber, and urges this diaphragm in the direction of the discharge side chamber. Spring, above? i:! A pressure switch having a pressure receiving pipe that opens into the discharge side chamber of the I control box, and a valve that opens and closes the opening of the pressure receiving pipe in conjunction with the diaphragm, and opens the pressure switch when the pump discharge pressure reaches a predetermined value. This automatic control device for an electric pump is configured to stop the pump, displace a diaphragm with a spring as the pump stops, and close a pressure receiving pipe of a pressure cassette inch with a valve.
