Topsflo TD5 washer

[paledragon]

Hey everyone,

I'm relatively new to the TD5 pumps after using March pumps for years. After a couple uses, I'm assuming something's out of whack with the TD5 based on the noises coming from it. I took it apart, and this washer seems to be bent. Any harm in just removing it, or should I dig up a replacement from somewhere like McMaster? I tried to find some exploded diagrams of the parts to no avail. The washer is from the motor side of the impeller.

Thanks,
p.d.

I found that it will run fine without that washer in place. Usually when those are bent, it's because someone took the motor apart and didn't realize the washer was there and then it gets put back together with the washer NOT pushed onto the impeller shaft, but just flopping around in the housing.
