I am in the process of dismanteling my pump, due to a small leak and noise/overheating.
I am a bit stuck as to accessing the bearings, could anyone help me identify the pump so I can check the correct procedure. As you will see it's quite old, all I can find is a square with a triangle inside and a circle inside that (maybe a logo?).
I don't have a complete picture as I didn't take one before I started to dismantle.
Here a some pics (you can just make out the logo in the one with the wet half attached):
