A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.
ANSI and IEC standard schematic symbol for a circulator (with each waveguide or transmission line port drawn as a single line, rather than as a pair of conductors). In electrical engineering, a circulator is a passive, non-reciprocal three- or four-port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after the one it entered.
An active circulator can be constructed using one of several different technologies. One early technology is the use of transistors as the active devices to perform the non-reciprocal function. [ 1 ] Varactor circuits are another technology, relying on a time-varying transmission line structure, driven by a separate pump signal. [ 2 ]
Three different high efficiency glandless circulating pumps designed and developed by the company Wilo. A high efficiency glandless circulating pump is a component of a heating and air conditioning system that allows the system to perform with increased efficiency while significantly reducing the system's electrical usage.
