Vertical Type

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. Public vertical multi-stage pump references identify common use 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. Submersible groundwater pump references from major pump manufacturers list these as typical applications for corrosion-resistant vertical borehole and groundwater pumps. 

 

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.

Engineering note 

Exact VMS-1180 flow, head, motor kW/HP, cable size, allowable starts/hour, minimum submergence, and material grade should be verified against the manufacturer’s pump curve and GA drawing before quotation or installation. The application mapping and operating envelope above are inferred from public vertical multi-stage and submersible groundwater pump references, where exact VMS-1180 model data was not available online.
