KEY FEATURES AND BENEFITS <br />Installation <br />• No baseplate or grouting required reducing installation costs <br />• No alignment required between the pump and motor with our <br />Lifetime Alignment Guarantee — eliminating laser alignment costs <br />and reducing installation time <br />• Optimized, space-saving design has up to a 35% smaller footprint <br />compared to traditional frame-mounted design pumps <br />• Top centerline discharge design allows for self-venting and more <br />compact piping designs <br />Efficiency and Reliability <br />• Industry leading efficiencies you can count on, because of advanced <br />Computational Fluid Dynamics (CFD) <br />• New Silicon Carbide (SiC) / Silicon Carbide (SiC) hard faced seal's <br />robust design offers increased temperature range, better abrasives <br />handling and longer life versus standard designs (standard on all <br />N-Series pumps) <br />• Backed by our Lifetime Alignment Guarantee so you never have to <br />worry about undue wear and tear on mechanical seals, bearings and <br />energy losses due to misalignment <br />• Optimized, stainless-steel impeller design increases efficiency and <br />reduces NPSH required <br />• Balanced impellers reduce noise and vibration for quiet operation <br />and prolong seal and bearing life <br />The N-series offers three different end-suction models: the <br />frame-mounted NK, close-coupled NB and split-coupled NBS. <br />The N-series delivers industry leading efficiencies that <br />future-proof them against government efficiency regulations. <br />The NBS is designed to bring faster installation, greater efficiency <br />and reliability, along with easier serviceability throughout <br />the pump’s life. With up to a 35% smaller footprint, Lifetime <br />Alignment Guarantee, back-pull out design and a new and <br />revolutionary hard-faced seal designed to improve reliability <br />and reduce service costs, the NBS delivers on our promise that <br />HVAC from Grundfos — it’s everyone’s comfort zone. <br />Split-Coupled End-Suction Pump <br />GRUNDFOS NBS <br />• 4" and above models have a internal dual-volute <br />design for increased efficiency, lower life-cycle <br />costs and prolonged seal and bearing life <br />• Integrally cast diffuser vane reduces turbulence <br />Serviceability <br />• Foot-mounted volute for increased pump stability <br />• Spacer-coupling design allows for back pull-out <br />and easy access to mechanical seal without <br />removing the motor or disturbing piping <br />APPLICATIONS <br />• HVAC (Cooling/Heating) <br />• District Energy <br />• Industrial <br />• Water Utility <br />L I F E T IME <br />GRUNDFOS <br />A <br />LIGN M E N T <br />Page 197 of 658
