Product Details
The 3171 vertical sump and process pump family is used where the hydraulic end operates below the mounting plate while the driver remains above the liquid level. A successful replacement depends on more than flow and head: the setting, column, shaft, steady-bearing arrangement, discharge layout and materials must be checked against the installed pump.
Vertical Sump Construction
A vertical sump pump typically uses a support plate at the pit or tank opening, a column and shaft system extending down to the hydraulic end, and a discharge arrangement matched to the setting. This construction can suit industrial sumps, tank unloading, corrosive liquid, drainage and selected high-temperature process duties where floor-mounted equipment is not practical.
Reference Operating Envelope
| Reference item | Installed-family reference |
|---|---|
| Flow | Up to 3,180 GPM (722 m³/h) |
| Head | Up to 344 ft (105 m) |
| Temperature | Up to 450°F (232°C) |
| Pit depth | Up to 20 ft (6 m) |
These values are installed-family reference information only. The selected setting, speed, hydraulic size, material, bearing arrangement and service conditions require engineering verification before order.
Shaft, Column and Steady-Bearing System
The shaft and column arrangement is central to a vertical pump replacement. Total setting, column length, shaft length, number and spacing of steady bearings, bearing material and liquid compatibility must be known. A pump that matches the flow but not the installed setting or support arrangement may not fit or operate correctly.
- Confirm total setting or pit depth from the support plate to the hydraulic end.
- State the column length and the number and location of steady bearings.
- Provide the discharge size, discharge-pipe arrangement and support-plate dimensions.
- Identify the driver, speed, coupling and mounting details.
- Report solids, temperature, corrosion and vapor conditions that influence material and bearing selection.
Hydraulic End, Sealing and Materials
Typical replacement review scope includes a fully open impeller, casing, suction cover, strainer, shaft, column pipe, discharge pipe, steady-bearing housing, thrust bearing, restrictor bushing and support plate. Depending on the confirmed part and size, material review may include cast iron, carbon steel, 316SS, Alloy 20, Hastelloy and duplex stainless steel. Final metallurgy is selected after the service and component are confirmed.
Standard vertical sump process configurations should not be labelled API 610, ISO 2858 or ASME B73.1 without a specific verified design basis. The model designation alone does not establish a standard classification.
Applications
- Industrial sumps and process drainage pits
- Tank unloading and chemical transfer
- Corrosive and non-corrosive liquid handling
- Pollution control and wastewater service
- Selected high-temperature and molten-sulfur applications
RFQ Information for Complete Pumps and Parts
For a complete-pump review, send the model, size, total setting or pit depth, column length, number and spacing of steady bearings, discharge size, speed, motor, flow, head, fluid, temperature, solids, material and seal or vapor arrangement. For parts, add the OEM part number, dimensions, drawing, photo and quantity. A general arrangement or sectional drawing is especially useful for vertical pumps.
Frequently Asked Questions
Why is total setting important?
The setting determines the column, shaft and submerged-bearing arrangement. It is required to verify fit and mechanical suitability.
Can you quote a shaft or steady bearing without a complete pump?
Yes. Provide the model, pump size, setting data, part number or drawing and material requirement.
Is a standard 3171 an API 610 pump?
No. Standard vertical sump process configurations should not be identified as API 610 unless a specific verified design basis applies.
What information is needed for corrosive liquid?
Provide the fluid chemistry, concentration, temperature, solids, operating time and existing wet-end materials.
What Buyers Commonly Search For
Common purchase-led searches include Goulds 3171 replacement pump, 3171 vertical sump pump, 3171 parts, 3171 shaft, 3171 steady bearing and vertical sump pump replacement. For this family, setting and column information are as important as the model number.
Choose the Fastest Next Step
- Complete vertical-pump replacement: send model, pump size, pit depth, column length and nameplate.
- Shaft, steady bearing or column part: send the OEM part number, dimensions, setting data and material requirement.
- Material review: use the chemical resistance guide, then send the process-fluid details for engineering confirmation.
