摘要： A pumping device having an identifying function is provided to allow cost reduction. A return channel and a delivery channel of a pump are connected to a suction tube equipped with a flowmeter, a return tube is connected to the return channel, a solenoid valve is disposed between the suction tube and the delivery channel, and a control unit identifying a fluid by a flow velocity difference of the flowmeter is disposed. The solenoid valve closes the delivery channel when a fluid flows in, the flowmeter measures a flow rate of a fluid sucked through the suction tube, and the fluid is returned to the return tube via the return channel. The control unit opens the solenoid valve to supply the fluid also to the delivery channel when it is identified that a fluid is an intended fluid.
