Flowserve SIHI LEH addresses chemical, pharmaceutical, petrochemical and general process vacuum duties. 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 liquid-ring vacuum-pump construction. 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 flows to 5150 m³/h; suction pressures to 33 mbar absolute; temperatures to 100°C; aTEX 2014/34/EU and NACE MR0175/MR0103 options. 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.
