Wet end seal for SIREM PB pumps
This mechanical seal is associated with the Ø 16 mm impeller and replaces the one found in the SIREM single or two-speed pumps with the PB reference, including the PB1C8024L1B pump manufactured before July 2018. It is not compatible with any other pumps.
The wet end seal ensures that the water doesn't leak out of the pump wet end, along the motor shaft. It comes in two parts: one mounts on the wet end and the other slots in behind the impeller.

This model of wet end seal is not compatible with SIREM PBL pumps (check the serial number on the cover of your pump), as the inside diameter of the ceramic part is too large. The PBL pumps and the PB1C8024L1B pump manufactured after July 2018 are supplied with a mechanical seal with a 12 mm diameter wet end seal.
