    Since I need to use my Karcher pressure washer "in the field", I will have to drive with my own water. My plan is as follows: a 1000l tank as the main water supply, from which it will draw the hydrophore (producing the necessary pressure for the operation of the washer, because my model is not able to collect water by itself) and further to the washer. As for electricity, it will be powered by a generator.
    Now for my questions, I have the following devices at my disposal:
    tank on a pallet - you know, rather nothing special Setting Up a Mobile Karcher Pressure Washer System with a 1000l Water Tank and Generator Setting Up a Mobile Karcher Pressure Washer System with a 1000l Water Tank and Generator
    above the nameplates of the pump and the pressure tank.
    What else do I need to buy besides the above? replaced components (not including pipes and fittings), I know that it would be useful to prevent the pump from running dry.
    Can the pressure supplied by the pump be somehow freely adjusted, so as to obtain, for example, a similar one as I have from a garden hose?
    Is an ordinary single-phase aggregate enough to power the pump and karcher, or does it have to provide some special stabilization, etc.?
    What else should I pay attention to so that such a system works flawlessly and efficiently?
    Regards.

    Why are you complicating your life? I would do this: a 1000 l tank on, for example, a trailer, properly elevated so that it is 1 m above the washer, supplying the washer with a suction hose with a diameter larger than the inlet to the washer. And last but not least, you can check the efficiency of the connection to the washer by draining the water from the tank and measuring the time. Compare that with the karcher-performance parameters and you'll know if it's enough. I power my washer from a hydrophore pump, but I also have a hydrophore which is used for storage and pressure equalization. Without a hydrophore, it will be hard for you because the pump will work non-stop, with a temporary interruption of Karcher's work, the pump works to the max. You would have to build in the overflow valve, it complicates the matter, unless Karcher will be far from the water tank

    I have a hydrophore, a tank of about 80l - I replaced it in my lumber. I decided on this solution because I don't want to be dependent on the position of the karcher (without a pump, it must always be below the tank to generate at least minimal pressure), the hydrophore also gives me such freedom that when I don't need very high pressure, I don't have to use a karcher because it is enough, for example, such as is in the garden hose - and this will be done by the pump.

    Well, use a pressure switch for the pump and the pump will turn on and off by itself, and use a liquid level sensor for the tank, it will protect the pump from "dry running" A single-phase unit is enough if Karcher and the pump motor are also single-phase and the power of the unit must be greater than receivers (washer and pump motor)

    With the power of the aggregates, hmm, it's always not enough, do the test, the washer needs a lot more when starting and stopping. Do a test before you go to the field, do you want to wash the facade signs cube??

    The stabilization unit does not have to have it, but if it is to work, it cannot be Chinese with aluminum windings and a power of at least 3kW (or even better), the karcher pump has a hard start (under pressure in the hose) and the crappy unit will do buuuuu and the pump will also do buuuu , then sit down and splash yourself with water to cool off your nerves.

    *must have this power on one phase because in 3-phase the common power is given.

    That's why I asked what should be washed, a man once called me from Krakow, he won a tender for washing road signs and signs. It turned out that the best solution would be to buy a petrol washer, water also drawn from a tank and so it washes without any problems, earning money and not getting nervous.

    Then take a petrol washer right away, a decent 1-phase 4-5kW generator is already a lot of money (without aluminum in the generator).

Topic summary

The discussion revolves around setting up a mobile Karcher pressure washer system using a 1000l water tank and a generator for field use. Key considerations include the need for a hydrophore to maintain pressure, as the Karcher model cannot draw water independently. Suggestions include elevating the water tank to facilitate gravity-fed water supply and using a larger suction hose. A pressure switch and liquid level sensor are recommended to automate the pump operation and prevent dry running. Concerns about generator power requirements are raised, emphasizing the need for a robust generator capable of handling the pressure washer's startup demands. Alternatives such as a petrol pressure washer are also discussed for efficiency and reliability in field operations.
