To create a vertical multistage in-line pump, grundfos was the first pump manufacturer ever to create a vertical multistage in-line pump. Known as the cr pump, this innovative design has inspired followers all over the world. The cr pump design has all the durability that customers expect from a high quality multistage pump. To ensure unsurpassed reliability, nnew features are added to ensure unsurpassed reliability. Dry running protection by introducing the grundfos liqtec. Aunique cartridge seal for a safe and easy handling. Hard-wearing materials. To make all the difference to pump efficiency levels, intricate measures were taken to make all the difference to pump efficiency levels. Internal leakage caused by the pressure differential within the pump was minimized. Enhanced impeller design resulted in a more streamlined flow in the impeller and reduced eddies and friction losses. By a small reduction in the pressure generated in each pump stage, aa higher specific speed [nq] has been achieved by a small reduction in the pressure generated in each pump stage. The grudnfos cr range provides offers variants in motors [flame proof], seals [double seal, quench] and pumps [magnetic sealless, air- cooled top] thereby providing an ideal mix and match for any conceivable industrial applications.
