Power washer issues

[Rich'sToys]

I hadn't used my Briggs & Stratton power washer for a couple years. Last week when I got it out I pulled the starter rope and it wouldn't budge. Today I pulled the pump off and, fortunately the engine turned over, but the pump is froze solid--rusted I assume. Apparently I didn't get quite all of the water out of it the last time I used it.
After digging out the owner's manual, I realized that I should also have been checking the oil in the pump once in a while! I didn't realize there was oil in it. Whoops!
The manual didn't specify what kind of oil, except that it came in small bottles with exactly the right amount for changing the oil. But all it says is "pump oil".
For now I turned the pump on its side and filled the cavity where the shaft from the motor goes with penetrating oil.
I'm not holding my breath that it will work, but on the off chance that I get this thing freed up, does anyone know what kind of oil to put in it?

Mine uses 30W engine oil. It's an Annovi Reverberi CAT pump.

Replacement pumps are available and not terribly expensive. There should be a data plate on the pump that will tell you the manufacturer and model number. Then just google that info to find an exact replacement.

It can be different depending on brand of pump if you get the tag on the pump and look that up it should say

If it’s locked up it’s new pump time. I know on hotsy’s and other heavy ones they rebuild them from time to time but I’m not sure on a small engine driven one if that be a good choice $$$$$ wise

I have never come across cross a B&S pressure washer. Is the pump bronze or cast aluminum? The aluminum ones are rated to last for 50 hours

If pump mfgr doesn't state what oil to use, imo it's pretentious for web buds to say.

I had one years ago, and I gave it to my son when I got a bigger one. I think we used 10-30 in it. I know I also saw at time washer pump oil but the 10-30 worked fine.

For future reference they sell pump conditioner/anti freeze to set the washer up for long term or cold storage.

Yea for the last few years I used 50/50 anti freeze in my pressure washer, foam marker system on my sprayer etc, so far so good.

RV antifreeze works well also.

I disable the ignition crank the engine over to exspell water at the pump. I then add 100% automotive coolant to the pump. I keep pulling the crank rope till it expels coolant. I made this contraption to fill the pump and keep coolant in the pump. If you look below the hose connection I made a nipple to go in the quick connect to seal that off. I had to replace the pressure adjustment device and the bolts that hold it on because of rust that's why I came up with a way to store it.

If it got below freezing, it is probably a freeze damage issue that keepst it from turning, not a lubricant issue.

It's always been kept in my heated shop. I also always pulled the rope a few times after shutting it down to get the water out of the pump, but possibly there was still a little in there--who knows? Haven't had time to mess with it the last few days. Hopefully I'll get back to it soon.

If it is aluminum pump they need protection from oxidation more than freeze protection.
