The Calpeda I-NC3 20-60/150 is a compact stainless steel in-line circulator pump designed for efficient hot water circulation in domestic, commercial and industrial heating systems. Built with threaded ports and a durable corrosion-resistant pump body, it is ideal for circulating clean hot water in closed-loop systems such as hydronic heating, boilers and recirculation lines.
Featuring three selectable speed settings, the pump allows manual adjustment of performance to match system demand, ensuring optimal energy use and quiet operation. The robust 2-pole induction motor operates on 230V single-phase power and includes integrated overload protection, IP44 enclosure rating and Class H insulation for dependable long-term service.
Engineered for high-temperature operation, the I-NC3 series handles liquid temperatures from approximately -10°C up to +110°C and working pressures up to 10 bar, making it suitable for demanding heating and circulation applications. The in-line design with suction and discharge on the same axis simplifies installation in existing pipework while maintaining efficient hydraulic performance.
With strong flow capability of up to approximately 55 L/min and maximum head around 6 m (60 kPa), the I-NC3 20-60/150 provides reliable circulation for medium-sized systems. Its quiet operation and compact footprint make it a practical solution for residential plant rooms, commercial facilities and mechanical services installations.
