Circulator pumps have numerous applications, but are particularly useful in heating/cooling systems and for hot water return. There are two types of circulating systems - open and closed. Closed systems are typically used for heating/cooling applications, such as underfloor heating or baseboard heating.
Axial-piston pumps consist of a set of pistons that are fitted within a cylinder block and driven by an angled swash plate powered by the input shaft. As the swash plate rotates, the pistons reciprocate in their respective cylinder block bores to provide the pumping action.ane-type pumps can handle inlet vacuum up to 6 in.-Hg (152.4 mm-Hg) and piston-type pumps up to 4 in.-Hg (101.6 mm-Hg). Noise and Vibration Vane-type pumps are the quietest and most vibration-free followed by piston-and gear-type pumps in that order.
