Product Description
The Double Pipe Vertical Sump Pump is a vertical submerged pump with double-column pipe design for enhanced structural rigidity in deep sump and tank applications. Its dual discharge and support columns minimize shaft deflection and vibration, while the submerged impeller provides self-priming operation. The pump handles flow rates from 2 to 100 m³/h at heads to 80 m and temperatures to 150°C, with 304/316L stainless steel construction. Suitable for deep chemical tanks, wastewater sumps, and industrial drainage requiring extended shaft lengths.
Applications
- Deep underground tank transfer
- Chemical storage tanks
- Sump drainage
- Tank farm operations
- Chemical processing
- Industrial wastewater
Quality Assurance
All Double Pipe Vertical 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.
Why Choose Our Vertical & Sump Pumps
Double Pipe Vertical Sump
Double-column vertical sump pump with separate discharge and support pipes, providing structural rigidity for deep pit installations.
Rigid Double Column
Double pipe construction minimizes shaft vibration and deflection in deep sumps up to 8 meters, extending bearing and seal life.
Corrosion-Resistant Options
316L, duplex, or fluoroplastic lined wetted parts for corrosive sump service in chemical, mining, and metal finishing.
Easy Maintenance
Rotating assembly removable from top without disturbing discharge piping, with accessible bearings and seal at discharge head.

Selection Guide
✅ When to Choose This Pump
- Below-grade tanks, pits, and sumps
- Corrosive waste collection and transfer
- Applications where NPSH is very low
- Plating tanks and chemical process vessels
⚠️ When NOT to Choose
- Above-ground installation (use horizontal pump)
- High-pressure multistage requirements
- Solids larger than 10% by weight
- Applications requiring frequent dry running
💡 Common Selection Mistakes
- Not specifying correct immersion depth
- Using standard bearings for corrosive vapor
- Ignoring shaft deflection at long lengths
- Not providing proper venting for submerged seal
