So due to the gasoline prices in Europe, i want to work completely electric.
Now, the issue is that there aren’t really ‘decent’ powerful enough electric pressure washers.
Most only reach 3200 psi, and at best 4 GPM.
Now obviously, i want to have 4000 psi, and 8 GPM.
If i understand correctly, I could get 8 GPM by combining (in parallel) two pressure washers of 4 GPM, right? however, that would still leave me with 3200 psi instead of 4000 psi.
This leaves me with a few ideas however I am not really sure about whether i’m right and where i can find the right equipment or how this could work.
I have 2 ideas, in general (apart from the above).
1 - would it work to buy TWO pressure washer pumps that NORMALLY fit on a gasoline powered pressure washer (like a honda), of 4000 psi and 4 GPM, then find a ELECTRIC motor with a shaft that produces enough RPM/Torque to replace the gasoline motor.
I haven’t been able to find a 8GPM 4000 psi gasoline pressure washer either, can anybody point me in the right direction? There aren’t that many products here in Spain, and Amazon only provides me with maximum of like 4 GPM machines (and extremely expensive).
2 - i was thinking of a totally different thing. How is pressure really created in a pressure washer pump? I mean there are home application pumps that people can use to like empty their swimming pools, or use to pump house water to a higher level. These can be of extremely high flow and are really inexpensive. For example there are Gardena ones of like 26 GPM for less than 300 USD.
However, it’s just 5 bars of pressure, so that’s like 80 times too weak.
It might be interesting as a softwashing application, but it does not bring enough pressure.
So, my question really is, are there independent machines/pumps that ONLY pressurize water, and if they do, does that influence flow?
simply put, can I add a device AFTER that water pump, to put PRESSURE to the water?
thanks so much!
ALSO, i’ve seen a ‘Comet TWS 8035S’ (google search ended up a store from monterrey, mexico).
it’s a 8,3 GPM 3500 PSI pump, says 20hp, but i don’t see it with a motor attached. Will have to write them.
i also found a Hidrocomet MB10ET4000-CMT 10HP, it’s a 4000 PSI 5 GPM pump including a motor. again, don’t know pricing, would have to ask, but it’s in mexico so still a thing. would cost a fortune to get it here i think. either way, if i would combine two of those, would i then essentially have a 4000 psi 10 gpm pressure washing setup>?
i also wonder what the prices are for these products and how to calculate kWh and amps used.
