Electric pressure washer

First off I can't stand the cheap garbage Walmart electric pressure washers. They are junk.
I bought a little project from the agg auction.
A real electric pressure washer, a 120/240v convertable 1.5hp 56C 2 pole motor on a stand with an obviously bad pump. It should do 2.2gpm at 1,500psi.
Since I have 240v 6-20 receptacles everywhere I will convert it to 240v power and buy a rebuilt general or triplex pump.
My gasoline powered pressure washer will do 2.5 at 2,500. I actually put a gauge on it. Might keep it, sometimes you just need the raw power.
2.2gpm at 1,500psi should handle most jobs.

It was already wired up for 240v but someone had a 120v plug on it. I bet it worked really good.
Rebuilt triplex or general pumps run around $250.
It will never pay for its self with gas savings.
I might see if a cheap gasoline engine pump will fit on there. I can take the one off my gasoline pressure washer. It has a 7/8 shaft. I can at least see of the gasoline and 56C face motor holes are the same, I think they are. The 56 frame motor has a 5/8 shaft. So I won't be able to test it.

Caught a new triplex pump on sale for $245 shipped from eBay. Its on its way. I have a 3 phase 6.5 amp motor overload that can be used for single phase. And will add a water proof 240v switch.
The built in motor over load was broken, got a slightly used full sized industrial one for $12.

I boguht a Karcher electric pressure washer for 20 bucks a few years ago, and haven't fired up my gas one since...it's nothing special, but 99% of my pressure washing is cleaning engines and such projects, and it's perfect and a heck of a lot more convenient for that.

I also have a 5hp 240v motor that I keep meaning to put my gas pressure washer pump on for when I have a bigger job, that I got 75% off. One of these days? Covid 19 might be good for getting caught up on such things!

I bought a gas unit. Shoot me.

I only wanted to buy one pressure washer, and I have a large enough property that the extension cord problem is not trivial, besides which I don't like the idea of the water and the electricity and the pressure being all together in one place like that.

I work in a wash down environment surrounded with 480v powered motors. All you need is good grounding and bonding to stay safe.
Then if you have a 120v pressure washer it should be plugged GFIC.
Mine is 240v and will no have such protection.

Here's the electric only version.

I bet it's going to have way more power than a cheap 120v Walmart pressure washers with similar claimed specs.

It's been working great so far. I can grab it, put the lines on and go.

That cat pressure washer gives my 240v 56c frame and "general pumps" clone of the triplex pump a run for its money.
I have a little over $300 in mine and the cat pressure washer is $225.
But mine is adjustable and fully rebuildable, serviceable, ect.
Oh and mine doesn't have a gfci so it might kill you, but that's highly unlikely as long as it has a good ground.
