Two Ø40x90mm bearings for both, the drive-end and non drive-end of the pump.
When bearings are renewed in a pump, we always recommend renewing of the mechanical shaft seals as well.Read More
There are two reasons for which we recommend you to replace the mechanical shaft seals concomitantly with the renewing of the bearings.
The first reason is due to accessibility. As a complementary replacement we highly recommend replacement of mechanical shaft seals as it is very easy to change them once the bearings have been dismantled from the pump and must be renewed.
The second reason for which we highly recommend you to replace the mechanical shaft seals as well, is to spare you money and time. In case that the mechanical shaft seals must be renewed short time after you renewed the bearings, you will have to renew the bearings again. This is due to the fact that when you must renew the mechanical shaft seals on the pump, you must first dismantle the bearings, which will cause an internal damage on the bearings. Although not always obvious to the naked eye, an internal damage of bearings always occurs when they are dismantled from the pump and therefore they must be changed.
