A pump body having a center body and a pair of side covers on both sides thereof, a drive portion having a shaft penetrating the center body closely, and a pair of diaphragms fixed to both ends of the shaft, A pair of pressurized chambers between the diaphragm and the side cover are connected to an inlet port and an outlet port of the main fluid through an inlet check valve that only allows fluid to flow in, and an outlet check valve that only allows fluid to flow out. In a diaphragm type pump in which a pair of drive chambers between the pump body and the center body are connected to a switching valve for supplying and discharging driving fluid, a pilot-driven switching valve is attached to the outer circumferential surface of the pump body, and the drive section is connected to the switching valve. A diaphragm pump characterized in that it is provided with a switching lever whose tip that is driven integrally with the pump body and projects outside the pump body operates a pilot valve of the switching valve. 2. The diaphragm pump according to claim 1, wherein the switching valve is a direct-acting type in which the valve body is driven by the pressure of a pressing member, and the switching lever is engaged with the pressing member. 3. The diaphragm pump according to claim 2, wherein the switching lever directly engages with the valve body of the direct-acting switching valve.
