Product Description
The 155B 12 mm mechanical seal is a single-spring replacement option for selected Lowara pumps. Begin matching with the 155B reference and 12 mm size, then check the complete removed assembly rather than choosing a seal from shaft diameter alone.
For a replacement enquiry, show the spring end and the face end of the rotating unit, together with the separate stationary seat. Include the seat outside diameter, thickness and the installed working length. These details help distinguish the required arrangement from other 12 mm seals.
Compare this reference with the other replacement mechanical seals for Lowara pumps. Where the existing part instead carries an 8731851 reference, use the separate 8731851 12/16 mm product page for identification; that listing is not an automatic substitute for 155B.
Our Lowara replacement seal selection guide explains how to put the pump nameplate, removed components and measurements together before requesting a quotation.
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
- Repair of selected Lowara pumps where the existing 155B configuration and 12 mm fit have been checked.
- Replacement identification using a complete removed seal, measured sample or installation drawing.
How to Confirm the Correct Replacement
| Pump identity | Supply the full Lowara pump model, product code and nameplate photo. |
|---|---|
| 155B configuration | Show the rotating spring assembly and stationary seat separately. |
| Installation fit | Record the 12 mm shaft or sleeve fit, seat dimensions and working length. |
| Service conditions | Provide the liquid, temperature, pressure and operating speed for material selection. |
Selection Questions
Does a 12 mm shaft diameter confirm a 155B replacement?
No. Use the 155B reference together with the stationary-seat profile, assembly dimensions and installed working length.
Are all 155B material combinations the same?
Specify the pumped liquid and operating conditions. The seal-face and secondary-seal materials must be confirmed for the supplied configuration.
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.
