The Flowserve LNN is an axially split, double suction pump design featuring 145 impeller and volute combinations resulting in quiet operation, low NPSH requirements, and high efficiency operation in all water applications.
Applications:
Food Processing, Offsites and Waste Treatment, Sewage Collection and Treatment, Shipping, Shower Pumps, Water Supply and Distribution (water), Water Supply and Treatment (oil and gas), Fire Protection, Cooling Water (metals), Water Treatment, Cooling Water (power), Auxiliary Services (power), HVAC, FPSO, Dewatering and Water Supply (mining), Nuclear Service, Drilling and Production, Ground Water Development and Irrigation
Industries:
General Industries, Mining, Oil and Gas, Water Resources, Primary Metals, Pulp and Paper, Power Generation
Double Suction Impeller and Heavy-Duty Double Volute Casing inherently result in optimum axial and radial thrust balance over the full operating range.
Hydraulically Balanced Double Suction Impeller reduces NPSH requirements and ensures smooth, efficient operation over a wide range of conditions.
Dynamically Balanced Impellers to ISO 1940 tolerances.
Independent Cast Seal Chamber housing for packing or mechanical seal.
Shaft conservatively designed to minimize deflection and reduce maintenance costs caused by wear.
