A circulator pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system (as opposed to lifting a fluid from a point of lower potential energy to a point of higher potential energy).
Circulator pumps as used in hydronic systems are usually electrically powered centrifugal pumps. As used in homes, they are often small, sealed, and rated at a fraction of a horsepower, but in commercial applications they range in size up to many horsepower and the electric motor is usually separated from the pump body by some form of mechanical coupling. The sealed units used in home applications often have the motor rotor, pump impeller, and support bearings combined and sealed within the water circuit. This avoids one of the principal challenges faced by the larger, two-part pumps: maintaining a water-tight seal at the point where the pump drive shaft enters the pump body.
Circulator pump production, which measures output worldwide, was expected to reach 19,365 thousand units in 2016 with an increase of 6.32% from its year-earlier level. The global circulator pump market size is estimated to grow from USD 3,440.62 million in 2011 to USD 3,622.49 million by 2016, at an estimated CAGR of 1% between 2011 and 2016. With regards to this, key players of circulator pump industry are expected to find potential opportunities in this market.
