Grundfos Alpha2 25-80 180 1X230V 50Hz 6H Circulator Pump

This is an encapsulated rotor pump, which means that the pump and motor form an integral unit. The bearings are lubricated with the pumped liquid, ensuring maintenance-free operation. The pump includes dry running protection. The pump has a ceramic shaft and radial bearings, carbon thrust bearing, stainless steel rotor sleeve, support plate and rotor liner, and composite impeller, all contributing to long service life. This pump is surface-mounted, so it must be out of water or liquid to function properly.
