Grundfos Alpha2 25-40 180 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. Insulation casings are supplied with the pumps to minimize heat loss in heating systems. 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. The pump casing is made of cast iron and galvanized to improve corrosion resistance.
