Burks 22106 Bronze Retaining Washer 0.50 in ID by 1.75 in OD
This is the bronze retaining washer Burks lists as part 22106 at 0.50 in inside diameter by 1.75 in outside diameter, on G9 series pumps on the larger motor frames pumps. It is the bearing surface the impeller fastener tightens against, and it is what keeps that clamping load distributed and consistent.
Washers dish, gall and corrode under the clamping load. A dished washer no longer holds the fastener tight, the impeller works loose on the shaft, and what follows is damage to the impeller bore, the key and sometimes the shaft itself.
Material and dimensions are both part of the specification. Bronze is what Burks fitted here, at 0.50 in inside diameter by 1.75 in outside diameter. A hardware store washer of similar size will not have the same corrosion behaviour or the same thickness, and thickness affects how the fastener loads the parts underneath it.

Frequently Asked Questions
Q: What happens if it is left out at reassembly?
That depends what it does. A missing load-spreading washer lets the fastener bite into softer material and work loose, while a missing slinger lets escaping liquid run along the shaft into the motor. Neither is worth the risk.
Q: How do I fit it the right way round?
Note the orientation of the old one before it comes off, and follow the Burks assembly sequence. Some of these parts have a chamfer or a dished face that belongs against a specific component.
Q: How do I tell if the old one is worn?
Lay it on a flat surface and look for rocking, which shows it has dished under load. Pitting, a witness mark from a fastener head, or corrosion that has eaten into the face are all reasons to fit a new one.
Q: Is it worth keeping a spare on the shelf?
Yes. Small items like this are what hold up a rebuild, and they take almost no space. Most operators keep them alongside the seals and gaskets for the pumps they run.
