CV 3171 Vertical Sump and Process Pumps
The CV 3171 from ITT Goulds Pumps is a vertical sump and process pump with a recessed impeller in a circular volute. It is sealless, and it will pass any solid that can pass through the discharge pipe, which makes it the gentle-but-tough option for large solids and shear-sensitive fluids.
Product Benefits
- Low-velocity pumping: The recessed impeller keeps liquid velocities low and minimizes contact between solids and the impeller, which cuts wear on the pump.
- Gentle on the product: Just as importantly, the product itself is protected: solids are not degraded and shear-sensitive fluids are not damaged on the way through.
- Minimal radial loads: The circular volute minimizes radial loads on the shaft, which is exactly what low-flow process service needs for long bearing and shaft life.
- Sealless and self-priming: Being sealless and self-priming, the pump removes seal maintenance from the equation in dirty sump duty.
Where It's Used
- Typical services: Duties include fibrous wastewater, industrial sump wastes and chemical slurries.
- Solids-laden pit duty: These are pit and process services where the liquid carries solids that would clog or wear a conventional pump.
- Product-sensitive processes: It is equally at home in low-flow process applications where product integrity matters.
Good to Know
- VS4 construction: The CV 3171 is a VS4-type vertical pump with a heavy-duty one-piece shaft and a double-row thrust bearing.
- Wide alloy range: It is available in a wide range of alloys to suit corrosive services.
- Vapor-proof option: Vapor-proof construction is optional for closed or fume-tight sumps.
- Check pit and temperature: The pump accommodates usefully deep pits and warm process liquids, so confirm your pit depth and temperature against the available range during selection.
