Product description

Flowserve SIHI Dry H-version addresses chemical and industrial vacuum duties where dry compression is required. 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 dry-running vacuum technology configured for process-specific duty. 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.

Selection should therefore be based on the exact operating point, medium properties, installation conditions, materials and sealing requirements stated for the required configuration. AxFlow can help compare the duty against the applicable Flowserve technical documentation.

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 SIHI Dry H-version is a dry vacuum system 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.
Check the required duty point, temperature, medium properties, materials, sealing and installation constraints before selection. The acceptable limits depend on the exact configuration. AxFlow can help verify the correct technical data for the required model.
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.
