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.
