Pump having a three-way valve

摘要

A pump having a three-way valve has a motor for generating a turning effect by an electric power applied thereto. The pump pressurizes a fluid by using an impeller. The three-way valve is installed to the inlet side of the pump. A magnetic plate and ball swing between the first inlet and second inlet by means of load switches as many as a predetermined angle. The pump and three-way valve are integrally formed to require no separate piping between the three-way valve and pump. Thus, the manufacturing processing of the boiler is reduced while enhancing productivity. An installation space is shrunken to decrease the external dimensions of a product such as boilers.
