Burks 22063-C Aluminum Bronze Shaft Sleeve 1.25 in OD by 2.13 in Long
This is the aluminum bronze shaft sleeve Burks supplies as part 22063-C at 1.25 in outside diameter by 2.13 in long, on G6 and G9 series pumps. It is deliberately the softer, cheaper part of the pair so that wear collects somewhere replaceable.
The sleeve wears where the seal elastomer grips it and where grit finds its way under the faces. A groove there stops a new seal boot from gripping properly, and the result is a seal that leaks within weeks of being fitted. Replacing the sleeve is far cheaper than replacing a grooved shaft, which is exactly the trade the design is making.
Size and material both matter. This one is 1.25 in outside diameter by 2.13 in long in aluminum bronze, listed for G6 and G9 series pumps. Burks chose the material for its wear and corrosion behaviour against the parts it runs with, so a dimensionally similar sleeve in a different alloy is not an equivalent.

Frequently Asked Questions
Q: Is the material a free choice?
No. Aluminum bronze is what Burks specified here, and it is chosen for how it wears against the mating part and how it stands up to the liquid. A harder or softer alloy changes which part of the pair wears out first.
Q: Should anything be fitted underneath it?
Follow the Burks instructions for the pump. Some arrangements use a sealing element under the sleeve to stop liquid tracking along the shaft, and leaving it out produces a leak that looks exactly like a failed mechanical seal.
Q: Can the old one be polished and reused?
Light polishing to remove discolouration is fine. Anything that has left a groove or a step is past saving, because the sealing element needs a smooth, round surface to grip and a polished groove is still a groove.
Q: How do I get a tight one off?
Work with heat and a puller rather than with force alone, and support the assembly so nothing is bent in the process. Burks service literature gives the method for the specific pump; improvising here is how shafts get damaged.
