Circulating Pumps

Circulating pumps are used to move slurries, liquids and gases through a closed circuit. They are usually employed to move hot water around a domestic heating system or in hydroponic cooling or heating systems. In a domestic heating system, circulating pumps enable an instant hot water supply on demand from a tap. Not only does this system save energy by avoiding the costly heating of large tanks of water, but it also enables a householder to save water. The energy needed to run the pump is far smaller than the energy required to heat and re-heat water tanks. The high-efficiency CP50 (60) circulator pump can also be used to control under-floor and radiator heating as well as all air conditioning and heating. Its operational temperature range is -10 degrees Celsius to +95 degrees C. Made with a cast-iron housing, it has an impeller made of polypropylene. It has integrated electronic controls to provide variable differential pressures. The CP SE60B circulating pump is used to provide a secondary supply of domestic hot water. This model has an impeller made of plastic that is reinforced with glass, carbon bearings and a ceramic shaft, all contained within a bronze housing. Ideally, it can be used on both new heating and cooling systems or as a replacement for existing or damaged pumps. The optimal use of this pump is for drinking water. It can be used in the food-processing industry to circulate potable water. It operates over a temperature range of +2 degrees C to +65 degrees C, with a maximum ambient temperature of 40 degrees C.
