Product Description
The GLF-12 hexagonal replacement mechanical seal is offered for selected Grundfos pump configurations. This listing identifies the hexagonal form; it should be matched to the removed seal as a complete assembly rather than selected from the GLF-12 reference alone.
For a useful comparison, photograph the top and side of the old seal, including the hexagonal section and any threaded area. Add the distance across the flats, mating dimensions and axial length. A similar outline is only a starting point: the quotation should identify the exact geometry and material combination that will be supplied.
Use the Grundfos replacement seal selection guide to organize pump information and the mechanical seal measurement guide to record dimensions. The GLF large-hexagon replacement seal is a separate listing for comparison, not an assumed interchangeable part.
For other Grundfos pump seal references and configurations, browse our complete Grundfos pump seal range.
Grundfos names and references are used for compatibility identification only. This is an independently supplied Hong Teng aftermarket replacement, not an original Grundfos part or an indication of affiliation.
Application
Suitable Replacement Enquiries
- Maintenance of selected Grundfos pumps with a matching hexagonal seal configuration.
- Replacement enquiries supported by the original seal, pump information or a verified installation drawing.
How to Confirm the Correct Configuration
- Provide clear top, side and underside photographs of the complete removed assembly.
- Record shaft fit, hexagonal flats, applicable thread details and stationary-seat dimensions.
- State the fluid and operating conditions; confirm the exact components required in the quotation.
Before ordering: Send the pump details and seal photographs to Hong Teng for confirmation of the required configuration and supply scope.
Product Questions
Is every seal described as GLF-12 the same?
Do not assume so. Match the physical configuration and installation dimensions for the pump being repaired, including the housing and stationary seat.
Is the loose accessory shown in a photograph included?
The supplied scope must be confirmed in the quotation. Request a parts list when the separate accessory is required.
Can I select it only by the hexagon size?
No. Include shaft fit, applicable thread dimensions, axial length and the mating seat so that the complete assembly can be compared.
