Introduction Features Literature

L1 AS16935 INNER-2LNNV Between Bearing, Axially Split, Single Stage Pump

Brand: Worthington
Description:

The Flowserve LNNV is a between bearings single-stage pump with an axially split casing, designed to deliver high flow rates with low to moderate head. Engineered for water transmission, power generation and industrial services, the LNNV offers excellent maintainability and mechanical reliability, even in continuous-duty operations.

The Flowserve LNNV is an axially split, double suction pump and is vertically mounted with in-line suction and discharge for space-saving flexibility. Featuring 145 impeller and volute combinations the LNNV provides quiet, efficient operation and low NPSH requirements in all water applications.

LNNV Between Bearing, Axially Split, Single Stage Pump Applications

Water Cooling, Water Supply, Water Treatment, HVAC, Irrigation, Sea Water, Flood Control, Fire Protection, Crude Oil Transfer, Cargo Loading and Unloading

  • Industries:
    Water Treatment, Miscellaneous Services, OEM, Utilities, Water Handling and Treatment, Water Supply and Distribution, Fire Protection – General Industry, Boiler Feed, Cooling Systems, Cooling Water – Metals, Desalination, Dewatering & Water Supply, Ground Water Development and Irrigation

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 meet ISO 1940 tolerances.

Independent Cast Seal Chamber accommodates packing or mechanical seal.

Shaft is conservatively designed to minimize deflection and reduce maintenance costs caused by wear.
