Description
The VMS-1180 is a vertical multi-stage centrifugal pump engineered for high-head water transfer where compact installation, stable hydraulic performance, and continuous-duty operation are required. Its stacked impeller-and-diffuser stage arrangement develops higher discharge pressure than a single-stage centrifugal pump while maintaining a narrow vertical footprint suitable for borewell, sump, tank, and pressure-boosting installations. Vertical multi-stage pumps are commonly used in water supply, pressure boosting, boiler-feed, cooling-water, irrigation, dewatering, washing, and fire-fighting services.
For submersible-type applications, the pump is suitable for clean or slightly contaminated water duties such as groundwater extraction, domestic and drinking-water supply, general irrigation, pressure boosting, groundwater lowering, fire-fighting support, cooling circuits, and industrial or municipal water transfer.
Technical Key Features
- Multi-stage high-head hydraulic design for pressure boosting and deep-well lifting duties.
- Integrated intake screening to reduce ingress of coarse suspended particles at the pump inlet.
- Low-vibration vertical assembly for stable operation in borewell, tank, and sump installations.
- Continuous-duty electric motor compatibility for municipal, agricultural, and industrial operating cycles.
- Vertical submersible configuration minimizes floor-space requirement and enables submerged operation.
- Corrosion-resistant wetted construction with stainless-steel hydraulic components for clean-water reliability.
- Application flexibility for groundwater, irrigation, building services, cooling water, washdown, and utility transfer.
