What is a Circulation Pump?
A circulation pump is a class of pump used to move gases, liquids, or semi-liquid material in a closed circuit. A common example of this type of pump is a water-based heating or cooling system. Due to their closed circuit design, this type of pump must overcome the force of friction within the piping system. The amount of effort required to do this is significantly less than in other types of pumping systems, where the pump would need to lift the fluid from the a low potential energy to a high potential energy. An electrical motor is the standard power source for a circulation pump. The capacity of the motor required is based on the size of the application. Industrial-sized pumps and the related motors are usually quite separate and are connected by mechanical coupling. Home applications are typically sealed units, with the pump and motor positioned very closely together. Enclosed within the circulation pump are the motor rotor, pump impeller and support bearings. The entire unit is se
