Product Description

Flowserve LPN addresses water and hydrocarbon transfer where low NPSH and medium pressure are important. It is relevant where equipment selection must balance hydraulic or process duty, operating reliability and maintainability. Correct sizing and configuration are important because unsuitable selection can increase energy use, wear and unplanned downtime.

The series uses single-stage between-bearings axially split pump with double-suction impeller. This construction is intended to provide stable process performance while giving maintenance teams a practical basis for inspection, servicing and component replacement. Configuration options should be matched to the pumped medium, installation arrangement and required operating point.

Current technical data for the series include high uptime made possible by double-suction impeller and double volute designs; superior performance at elevated temperatures. These limits and options are selection criteria rather than universal operating points, so the final duty should be checked against the exact pump or valve configuration.

For lifecycle cost, the main value comes from selecting the correct hydraulic or control configuration and maintaining the equipment before wear develops into a process interruption. AxFlow can support model selection, service planning and spare-parts requirements to help reduce downtime risk over the equipment life.


Flowserve LPN is a axially split process pump used in industrial process duties where reliable operation and correct application matching are important. The exact suitability depends on the medium, duty point and installation conditions. AxFlow can help confirm the appropriate configuration.
Start with flow or capacity, pressure or head, temperature, medium properties and installation arrangement. Then check materials, sealing, driver or actuator requirements and any applicable standards. AxFlow can support the selection against Flowserve technical data.
Key published selection data include High uptime made possible by double-suction impeller and double volute designs; Superior performance at elevated temperatures. These values define the documented range and should not be treated as the operating point for every configuration. The final selection should be confirmed for the exact model and duty.
Lifecycle cost is influenced by correct sizing, operation near the intended duty and timely maintenance. A configuration that matches the process can reduce wear, unnecessary energy use and avoidable interventions. Planned service and correct spare parts also help protect process continuity.
AxFlow can support product identification, technical selection, service planning and spare-parts requirements for Flowserve equipment. For legacy products, support may focus on maintaining installed assets or identifying a suitable replacement. Contact AxFlow with the nameplate data and process duty for the most accurate guidance.
