Yeah, Ive always noticed that. Whats odd is that any product page you
see on the net clearly shows the CAT pump, except for a couple images
off Amazons site. Even the display model at HD has the CAT pump.
What scares me about this pump is that its not a "sideways"
orientation, like all of the other pressure washer pumps Ive seen.
Rather it connects straight off the engine, and the plungers are
vertical to the pressure washer frame itself. There are thin metal
bands going from the bottom of the pump mount to the top above the
plungers. Its a really odd setup, at least from the research Ive
done. It looks like the crank turns the pump, and the plungers are
connected to some sort of oblong bearing and as the crank from the
engine turns the oblong bearing lifts the plunger (possibly by the
thin metal band on the outside, I couldnt tell).
I cant find anything like it on the net. I shoulda taken pics before
I boxed the thing back up again.
It really seems like some Dewalt/Devilbiss proprietary setup, and I
dont understand why anyone would pay extra for that. If I wanted
proprietary Id buy a Karcher for half the price. Im hoping that HD
will open a couple of them up for me and Im praying that we find one
with a CAT pump. Only other alternative is to buy the display model
(Id make them disco it heavily), or just return it altogether.
Really disappointing.
