Burks 2-21003-35 Washer - Pump Replacement Part
The Burks 2-21003-35 is a replacement washer. It is inexpensive, it is inside the pump, and it is the kind of part that turns a routine rebuild into a repeat job when it is left out.
Corrosion is the usual reason to change one. Once the face is pitted, the clamping load is carried unevenly and the fastener will not stay tight, and a fastener that will not stay tight on an impeller is a problem that escalates quickly.
Fit it as part of the wider job. Whenever the impeller or the seal is off, this is the moment to renew the small items around them rather than to judge them by eye.

Frequently Asked Questions
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.
Q: Can I substitute a standard washer of the same size?
It is not a good idea. The material, the thickness and the surface finish are all part of what Burks specified, and this part sits in a wet, sometimes corrosive location under a clamping load that has to stay constant.
