overview
Horizontal Multistage Petrochemical Pump construction and operation
Horizontal, radially split multistage process pump
The impeller transfers energy to the liquid through the pump casing. Final selection depends on the model curve, liquid properties, sealing arrangement, drive and piping conditions.
A horizontal multistage pump for high-head refinery, petrochemical, coal-chemical, boiler-feed and water-injection duties.
- Horizontal radially split segmental multistage construction
- First-stage inlet conditions and later-stage duty require a complete curve
- Seal, flushing and cooling systems follow the selected process conditions

applications
Typical applications
refining
For refining, check the applicable product curve, liquid properties, required operating point and installation geometry. Check the proposed arrangement against horizontal segmental multistage and process-specific material schedule, then verify the operating point on the selected model curve.
petrochemical processing
For petrochemical processing, provide the complete composition, concentration, temperature and seal-utility requirements. Check the proposed arrangement against horizontal segmental multistage and process-specific material schedule, then verify the operating point on the selected model curve.
coal chemical processing
For coal chemical processing, provide solids concentration, particle grading, suction conditions and pipeline resistance. Check the proposed arrangement against horizontal segmental multistage and process-specific material schedule, then verify the operating point on the selected model curve.
boiler feed
For boiler feed, confirm viscosity, temperature, suction conditions, seal plan and pressure envelope. Check the proposed arrangement against horizontal segmental multistage and process-specific material schedule, then verify the operating point on the selected model curve.
water injection
For water injection, check the applicable product curve, liquid properties, required operating point and installation geometry. Check the proposed arrangement against horizontal segmental multistage and process-specific material schedule, then verify the operating point on the selected model curve.
