Burks 7495 Washer - Pump Replacement Part
The Burks 7495 is the genuine Burks washer. It spreads the clamping load from the impeller fastener across the impeller hub, so the load arrives evenly rather than through a fastener head digging into a softer casting.
Replace it with the impeller fastener rather than reusing it. It costs very little, it is buried behind the impeller, and reaching it again means taking the wet end apart a second time.
Material and dimensions are both part of the specification. 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: 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.
Q: Does this need replacing every time?
Inspect it and renew it whenever the part it works with is being replaced. It is inexpensive, it is inside the pump, and a second strip-down to fit a small part is an expensive way to learn the lesson.
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.
