Product Description
The Vertical Multistage Sump Pump is a vertical submerged pump designed for underground tanks, pits, and sumps where positive suction pressure is unavailable. Its multistage bowl assembly delivers heads up to 300 m from a single vertical column, while the submerged impeller ensures self-priming operation. The pump handles flow rates from 2 to 200 m³/h at temperatures to 150°C, with column lengths customized to sump depth. Suitable for chemical storage, wastewater, and industrial drainage applications.
Applications
- Underground tank transfer
- Sump drainage in chemical plants
- Condensate extraction
- Boiler feed water
- Cooling water circulation
- Industrial pit drainage
Quality Assurance
All Vertical Multistage Sump Pumps are manufactured under ISO 9001 quality management system. Each pump undergoes rigorous testing including hydrostatic pressure test, performance test, NDT inspection, and dynamic balance verification before shipment. We provide comprehensive documentation including test reports, material certificates, and operation manuals.
