adhikari_s


I am looking for a pressure pump(washer) that generates 1500-5000 psi applying 12V DC battery. How many batteries required ?
Can I buy such pumps in the market ? please give more information on it.



Answer
My pressure washer has a 5 horsepower motor and creates about 200 psi. The short answer is that car starter motors create 5 to 10 hp for a short while but get hot fast. One battery will do the job for a very short while. The easier way is to use an electric washer, convert the 12 vdc to 120vAC with an inverter and wash away. The amount of batteries will depend on how long you want to operate at high pressure. The more the better. Can you buy such a pump, sure, convert a small home electric unit. Another good source for this stuff is West Marine, check their website and they have a great tech staff and no I don't work there.

Car Pressure Washer Help..?







I am looking to buy a pressure washer for cleanin my car.I am only looking to use it for cleaning my car and nothing else really.I was wondering what would some people recommend? If they have bought a good one and its going strong,etc..

Im in ireland FYI..Not really looking to spend more than â¬120-â¬150 ish but want a good solid pressure washer for that price..Thanks



Answer
most car detailers would say a pressure washer will do more damage to your car paint than good
Perhaps it will be useful on like tires.

If you want to buy something to make your washing easier, you should look at a foam gun/cannon/lance instead.
