Horizontal Type

Description 

The HMS-1170 Horizontal Multi-Stage Pump is an industrial centrifugal pump designed to generate elevated discharge pressure by routing liquid through multiple impeller stages mounted in series. This configuration is suitable where a high head is required while maintaining stable flow, making it appropriate for pressure boosting, clean-water transfer, boiler feed, reverse osmosis feed, HVAC circulation, and utility-water distribution duties. Horizontal multi-stage pumps are widely used for high-head pressure boosting and liquid transfer applications across industrial water systems. 

 

Engineered for continuous-duty plant operation, the HMS-1170 is suitable for clean water, treated water, condensate, softened water, cooling water, and compatible low-viscosity process fluids. Typical application areas include water treatment, air-conditioning, industrial heating/cooling circuits, process-water boosting, industrial washing, boiler feed, and RO systems. 

 

 

Technical Key Features 

• Robust cast construction for general industrial duty, vibration resistance, and long operating life. 

• Mechanical shaft seal arrangement suitable for clean water and compatible process-water services. 

• Electric motor-driven configuration compatible with fixed-speed or VFD-controlled booster systems. 

• Flanged suction and discharge connections for rigid pipework integration in industrial utility systems. 

• Suitable for continuous service in boiler feed, RO feed, water-transfer, and pressure-boosting systems. 

• Horizontal split service envelope allowing easier access for coupling, seal, bearing, and alignment work. 

• Multi-stage hydraulic design for high-head, high-pressure operation with stable discharge performance.

Verification notes 

HMS-1170 model-specific curve data, NPSHr, motor rating, exact flange standard, seal code, and certified pressure/temperature limits were not publicly confirmed from the searched sources. The values above are professional catalogue defaults inferred for a horizontal multi-stage centrifugal pump and should be verified against the final pump curve, GA drawing, and purchase specification before release.
