Grundfos UP 15-55 SUC circulator pumps deature a corrosion-resistant bronze pump housing, making them ideal for drinking water applications, while Grundfos UP N models are equipped with a stainless-steel pump housing for enhanced durability and hygiene. Both variants are highly recommended for underfloor heating systems, where the pumped liquid may become aerated. In such conditions, bronze and stainless-steel housings help prevent corrosion, unlike traditional cast iron pumps. This circulator pump utilizes a canned rotor design, meaning the pump and motor are integrated into a single, compact, leak-free unit. It operates without a shaft seal, reducing maintenance needs and improving reliability, with only two gaskets required for sealing. The pump's self-lubricating bearings, lubricated by the pumped liquid, ensure quiet operation, long service life, and maintenance-free performance.
