| Product Reference | GLF — large-hexagon type |
|---|---|
| Supplier / Brand | Hong Teng |
| Place of Origin | China |
| Compatible Equipment | Selected Grundfos pump configurations |
| Identification Feature | Large hexagonal section with a threaded housing, as shown |
| Size Information | Confirm shaft, housing and thread dimensions from the actual assembly |
| Application | Replacement of the matching large-hexagon seal configuration |
| Enquiry Information | Pump identity, top and side photos, across-flats measurement and installation dimensions |
Product Details
| Model / Reference | GLF (large hexagon) |
|---|---|
| Configuration | Large-hexagon replacement seal; compare the complete assembly rather than the hexagonal outline alone. |
| Hexagonal Section | Record the distance across flats and the space available around the installed seal. |
| Threaded Section | Confirm mating thread diameter, pitch and engagement geometry using the removed part or pump drawing. |
| Shaft and Bore | Provide the shaft or sleeve diameter and the required mating-bore dimensions; no numeric shaft size is assumed here. |
| Axial Fit | Compare overall assembly length and the installed position relative to the pump housing. |
| Sealing Interfaces | Check the mating seat, secondary-seal locations and any separate parts associated with the original assembly. |
| Materials | Confirm the seal-face pair, secondary seals and metal specification for the actual liquid and operating conditions. |
| Supply Confirmation | The quotation should identify the exact reference, dimensions and included components. |
| Alternative Listings | GLF-12 hexagonal and other GLF references require their own fitment check; similar names do not establish interchangeability. |
Product Description
The GLF large-hexagon replacement mechanical seal is listed for selected Grundfos pumps requiring this assembly form. The broad hexagonal section and threaded housing are useful visual identification points, but the final match must include the mating connection and axial installation geometry.
Send a side view showing the full threaded portion and a top view showing the central opening and hexagon. Where a sample or drawing is available, include the distance across flats, shaft fit, thread details and total assembly length. These details make the enquiry more specific than a request for a general GLF seal.
Compare other options through the Grundfos replacement seal range and use the mechanical seal measurement guide for the dimensional record. The separately listed GLF-12 hexagonal mechanical seal is provided as a comparison reference only; do not assume it can replace the large-hexagon version.
This is an independently supplied Hong Teng aftermarket replacement. Grundfos names identify compatible applications and do not imply original-part status or affiliation.
Application
Suitable Replacement Enquiries
- Maintenance of selected Grundfos pumps with a matching large-hexagon seal assembly.
- Replacement work supported by a complete sample, installation drawing or confirmed pump-and-seal specification.
How to Confirm the Correct Configuration
- Photograph the full assembly, including the hexagonal section, thread and mating end.
- Supply the shaft or sleeve diameter, across-flats dimension, thread measurements and axial installation length.
- Identify the pump product number and requested material configuration; confirm any separate parts to be supplied.
Before ordering: Send the pump details and seal photographs to Hong Teng for confirmation of the required configuration and supply scope.
Product Questions
Does a larger hexagon mean a larger shaft diameter?
The hexagonal section does not provide a complete shaft-size specification. Measure the shaft fit separately and compare the drawing.
Can this replace the GLF-12 hexagonal seal?
Only after the relevant dimensions and equipment configuration have been matched. The two catalogue references are not treated as interchangeable here.
What should I send when there is no readable seal number?
Send the pump nameplate, full assembly photographs and dimensions, especially the shaft fit, across-flats measurement, threaded section and overall length.
