What is a suction bell?
A suction bell provides an enlarged inlet form for a specified suction arrangement. The opening, transition and outlet connection must be selected as part of the pump or intake design.
Key dimensions and installation fit
The suction bell forms an enlarged inlet at the end of a suction pipe. Compare the connection outside diameter, mouth diameter and installation clearance with the intake arrangement. The nominal pipe size describes the connection; the larger bell opening defines a different part of the geometry. Compare the concentric pipe reducer when distinguishing an inlet bell from a size transition between two pipe connections.
How to specify the suction bell
Choose the material and surface protection for the fluid and installation environment. Coordinate the bell shape with the pump or intake design, supports and surrounding structure. The bell dimensions alone do not establish flow capacity, suction performance or the submergence required for the completed system.
Technical data for the suction bell

Sizes and dimensional requirements
The dimensional schedule identifies the illustrated configuration. Compare each value with the mating pipe, equipment or support drawing. A nominal designation does not replace the actual connection diameter, installation envelope or mounting detail. The choices above let you include a different configuration with your quotation request.
Dimensions and tolerance schedule
| Machined length >30–120 mm | ±0.3 mm |

| Machined length >120–400 mm | ±0.5 mm |
Inspection, standards and documentation
Inspect the connection, inlet edge and formed shape against the specified drawing. Include weld preparation, coating and marking requirements in the order. State whether the bell is supplied alone or as part of a pipe spool so the attachment and handling details can be reviewed together.
State the required product standard and edition, material records and inspection acceptance criteria before ordering. Where pressure, temperature, movement or load are relevant, provide the operating and test conditions together. Document requirements should identify the actual component and drawing revision; a general certificate does not replace a dimensional or material record for the ordered item. For production steps and inspection considerations, see flanges and fittings manufacturing.
Where the suction bell is used
- Pump intake arrangements. Coordinate inlet geometry, mounting clearance and the suction pipe connection.
- Water intake assemblies. Select the material and protection for the installation environment.
- Custom suction spools. State whether the bell is supplied separately or with a connecting pipe section.
How to order a suction bell
Select the required options and send the quantity, destination, material and controlled drawing to JINYI. Include changed dimensions, mating details, finish, marking and packing requirements. The quotation defines the final configuration, inspection scope and delivery terms so the component can be checked against the intended installation.
Quantity prices and order preparation
| 5–49 pcs | US$100.00 per piece |
|---|---|
| 50–199 pcs | US$95.00 per piece |
| 200 pcs and above | US$90.00 per piece |
Freight and taxes are quoted separately. A different material, size or drawing can change the price and delivery requirements. Confirm the agreed specification before manufacture, and keep the drawing revision, selected options and ordered quantity together in the enquiry.

Suction Bell selection and quotation checklist
The expanded mouth belongs to an inlet arrangement. Identify the attached pipe, inlet orientation and surrounding installation space; the nominal connection size does not describe the mouth. Use the photographed product form to identify the arrangement, then use the controlled drawing to define what will be supplied. Similar-looking components can have different end details, load paths or maintenance requirements.
Suction Bell dimensions and tolerances
The first comparison for this suction bell is mouth diameter and inlet connection. Mark the dimensions that control mating, alignment and installation space on the enquiry drawing. Give units for every value and identify the datum from which it is measured. If a dimension is critical, specify its individual tolerance and measurement method rather than relying on a general tolerance note.
The current schedule identifies nominal size: DN100; connecting pipe outside diameter: 114.3 mm; mouth diameter: 275 mm. Read these entries together with the configuration and tolerance tables above. Reference or example values describe the displayed arrangement; the approved JINYI quotation and drawing define the ordered component. A different interface, material or service condition needs a fresh comparison.
Prepare the material and interface information
For a suction bell enquiry, identify the required material designation and supplied condition. Describe the mating components, attachment method and environment. Include the operating temperature and any relevant pressure, movement or structural load. These inputs should describe the actual installation, including changes between normal operation, start-up and maintenance where applicable.
Specify coatings, surface finish and marking separately from the base material. If traceability is needed, identify the record required and how it must correspond to the delivered component. Agree whether inspection covers dimensions, material documentation, welds or functional testing; these are different checks with different acceptance criteria.
Custom suction bell quotation
Attach the latest drawing revision, required quantity and delivery destination when contacting JINYI. Highlight departures from the illustrated arrangement, including changed dimensions, connections, finish and packing. For repeat orders, reference the approved configuration and list changes explicitly so an earlier drawing is not assumed to remain current.
The three price tiers above organise the displayed quantity bands. Compare quotes using the same drawing, material, inspection scope and unit of supply. A piece, a segment and a complete assembly are different units where applicable. Confirm freight, taxes, documentation and delivery terms with the final quotation instead of inferring them from the displayed unit price.
Compare related component arrangements
Evaluate this suction bell by its actual mouth diameter and inlet connection and the required bell mouth arrangement. The photographs below show separate JINYI products for comparison. They are linked to their own technical pages and are not additional gallery views of this suction bell.

Questions to resolve before ordering
Which dimensions need checking first?
Start with mouth diameter and inlet connection and the mating or mounting detail. Check nominal designations against measured dimensions, then review the installation envelope. Photographs help identify the form; the drawing provides the dimensional basis for acceptance.
What should the quotation include?
A suction bell quotation should identify the configuration, drawing revision, material, quantity, price basis and agreed inspection records. Keep these details together with the approved order so receiving inspection can compare the delivered product with the specified component.
Independent terminology reference
ASME butt weld fitting standard scope provides an independent reference for component terminology. Use the specified standard and edition where required by the project. This link does not establish JINYI certification, product approval or interchangeability with another manufacturer.
