  • 3000 PSI washer - pump questions

    Hi everyone, I am in the process of looking to purchase a used unit on my local craigslist, and I had a questions regarding the pump on what I can only assume is an RD80704 or RD80701.

    The pictures the seller sent me show a silver looking pump, similar to the one found

    The one I was hoping/expecting to see was a blue pump, which I assume is the much praised CAT pump, as seen

    I've heard of instances where retailers would sell units advertised with a CAT pump, only to find out it is another brand. Obviously I'm basing this on a very flaky conclusion that a blue pump = CAT.

    Does anyone have any experience with this? Thanks.

    The silver pump is an AR axial cam. The unit with the silver pump (top pic) is model # RD80746.
    The blue pump is a CAT triplex. The model # for the unit pictured (the lower pic) is RD80701.

    Same engine, same frame. Just a different pump.

    If you buy the RD80746 (the one with the silver pump), make sure you're budgeted for pump replacement... their longevity is somewhat less than stellar.
