CIRCULATION PUMPS KP.GRS-25/4-130, KP.GRS-25/6-130

Circulation pumps with an installation length of 130 mm are used for pumping heat transfer fluid in heating systems, floor heating systems, hot water supply systems. The heat transfer medium can be either pure fresh water or a liquid with 50% glycol impurities. Pumps of this type significantly improve efficiency of heating systems. The pumps are characterized by low noise level, simple and reliable design. They are a good solution in apartments, private houses, cottages, agriculture, warehouses.
