A condensate pump is designed to pump condensate water produced by conditioned building air that has been cooled or heated, including refrigerated or freezer air, boiler steam in heat exchangers and radiators and furnace exhaust streams. As its names suggests, a condensate removal pump is used to extract condensate from the HVAC system’s pipework and move it around the plant where it can be treated, converted back to steam and then pumped back into the system to be reused.
Air conditioning condensate pumps usually only have to handle relatively clean water condensation, whereas steam condensate from boilers and furnaces often includes contaminants including dust, or chemicals from an exhaust system. Therefore boiler and furnace condensate pumps need to be able to cope with more demanding conditions. Side channel pumps are usually the best options for condensate water pumps thanks to their ability to handle liquids with gas and air content.
