Grundfos Pumps is the only manufacturer of large, wet rotor circulators in the U.S. commercial market with a proven track record of more than 25 years experience. Our VersaFlo® UP(S) wet rotor circulators are whisper-quiet and maintenance-free. They feature an integrated pump and motor design. Fewer parts means greater ease of installation and durability.
Grundfos vertical in-line pumps are used in commercial buildings for air conditioning and heating applications. The pumps are all single-stage, in-Line centrifugal pumps with standard motor and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pumps and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.
