PROBLEM TO BE SOLVED: To solve the problem that smooth operation is impeded by terminating a pump discharge function caused by air lock due to a gas generated in a chemical dosing pump from a chemical in many application examples using a water purifier of well water and other chemical dosing pumps. SOLUTION: Chemical dosing equipment without using a chemical pump and without generating an air lock phenomenon even if a large quantity of gas is present in the chemical is obtained by installing an ejector on a main pipe through which well water or the like flows and sucking the chemical from a suction part of the ejector to mix with the well water or the like.
