The LNN series of pumps is the outcome of many years of experience in the design and manufacture of axially split casing pumps. State-of-the-art pump design technology from Flowserve has resulted in superior pump designs which offer broad hydraulic coverage, quiet operation, low NPSH requirements, high operating efficiency and low total cost of ownership.

- Separate 360° bearing housings provide superior bearing stability and shaft support while easing maintenance
- Perfect shaft alignment is assured by a full register fit to the casing
- Axially split casing with suction and discharge nozzles integrally cast in the lower casing half permits pump disassembly without disturbing the piping or driver
- Upper casing half does not have to be removed to access bearings, packing, mechanical seals, sleeves or sleeve nuts
- Nozzle flanges meet the dimensional requirements of ASME B16.1, B16.5 or ISO 7005 part 1 or 2
- Flanges are available in sizes from Class 125 to Class 300 (ISO PN10 to PN63)
- Flowserve
- ISO 13709 / API 610
- Flows to 30,000 m3/h (132,000 gpm)
- Heads to 300 m (985 ft)
