ASPE Product Overview--Centrifugal Pumps
Grundfos has announced the expansion of its CR series of centrifugal pumps. With the release of the CR 1s, 1, 3, and 5, the CR range has been supplemented with new sizes and a narrower interval between sizes, as well as technology and innovative design. The shaft seal on the new pumps is now more reliable and easier to work with, and the efficiency has been boosted to new levels. To address the problem of dry running, more durable materials were used in the pump's construction, plus a unique cartridge seal was developed to simplify and speed up seal replacement, and Grundfos LiqTec was developed to stop the pump the moment it runs dry.Grundfos.
