Cyclone / Series 3
The pump works

I replaced the pump in my other sprayer. I had only been running it for about 6 months and the whole interior of the motor was rusted out. I have both the cyclone and the typhoon. Go with the typhoon because the motor is most metal and not plastic. Easy to replace part though for only 44 bucks, so hard to find a better deal.
