Subject: Procon pump (?) bearing replacement?
|
I am trying to recondition a pump that looks like a Procon. The
sticker on the end plate is missing. The problem is that it has a
metric outer diameter of 30mm, and an imperial inner diamter of
7/16. The numbers on it seem to be 6002A 2RSR CSFR. A standard
6002 is 30mmx10mm, but the shaft is definitely an imperial, measuring
11.1mm
Can anyone help me with what the correct replacement bearing is?
I would consider turning down the shaft of the rotor to 10mm, but it
looks like its well hardened.

Does anyone have any idea how stiff an unworn rotary pump should be?
I have replaced the bearing in my pump, but while now being smooth to
turn, it is still too stiff to turn by hand. I need to use a small
spanner on the shaft. What seems to have caused the extra friction
is the removeable portion of the pump chamber that is held in
alignment by a pin and secured with the rear seal and screw-in seat.
This was stiff to press in, and now that it is pressed in, I don't see
how I can remove it again to investigate. (A bit of a Doh! situation
in other words ...)
Any ideas or help would be appreciated.

I've not worked on a Procon pump, even though I have two at work. I have worked
on many industrial vaccum pumps, they are vane pumps, too. In those, the dowel
pins are removed by using a punch to press them out the other side. If you have
'blind' pins that won't be a possibility. Another option may be using a bearing
puller.
Have you tried operating the pump and letting it 'run in?' Of course, you'll
want to do that using water. I have rigged plastic hosing from the pump's inlet
and outlet, and put them into the same 5-gallon pail of water and just let it
recirculate.

It turns out that the shaft wasn't has hard as I thought, so I turned
it down to 10mm and have bought a standard 6200 bearing. I'll fit it
tomorrow, so hopefully everything will be good to go again after
that ...

Kewl! And the standard sized bearing is going to be cheaper, too.

Nick, Now you know why it is a 6002 'A', it is an OEM item, made just for the
mfgr. Still, I have seen some mixed units bearings. Try a bearing supply house.
When all else fails, try Procon parts department. Dan
