Product Description
This 8731851-reference mechanical seal listing covers 12 mm and 16 mm replacement enquiries for selected Lowara pumps. Confirm the exact size and corresponding seat for the pump being repaired. The two sizes are separate selection requirements, not a claim that one seal fits both shafts.
The product images show the spring-loaded assembly and a separate mating seat. Send photos of both parts, including the seat profile and any visible markings. Use the reference number together with the nameplate and measurements rather than relying on the number alone.
For other options, see the replacement mechanical seals for Lowara pumps. The LOWARA-16L-X 16 mm mechanical seal has its own product listing; a shared 16 mm size does not establish equivalence.
The mechanical seal identification guide explains which pump details, component photos and measurements to send for checking.
Compatibility notice: Lowara and related reference numbers identify the intended application only. This replacement is independently supplied by Hong Teng and is not an original Lowara part.
Application
- Replacement enquiries for selected Lowara pumps where the 8731851 reference and installation dimensions are being checked.
- Maintenance of the corresponding 12 mm or 16 mm seal configuration after the correct size and seat have been identified.
How to Confirm the Correct Replacement
| Reference evidence | Send the document, packaging label or old component showing the 8731851 reference, if available. |
|---|---|
| Exact size | State whether the required shaft or sleeve fit is 12 mm or 16 mm; include measurements. |
| Mating seat | Provide its outside diameter, thickness and seating profile, together with the rotating assembly. |
| Operating conditions | Specify the pumped liquid, temperature, pressure and speed before confirming materials. |
Selection Questions
Does this page mean a single seal fits both 12 mm and 16 mm shafts?
No. Confirm the individual size and corresponding seal arrangement for your pump before ordering.
Can reference 8731851 replace a full dimensional check?
No. Use the reference as part of the identification record and compare the pump model, seat and installed length.
Important: Confirm the complete rotating and stationary parts, installation dimensions and material configuration before ordering. The listing does not establish interchangeability with another reference.
Send the pump nameplate, seal photos and dimensions for a quotation.
