piston yan. see the 3 cylinders at the bottom?. afaik you can't generate high pressure w/ centrifugal
I didn't check the picture earlier... and yes, I couldn't see the usual "volute casing" so this doesn't qualify as a centrifugal pump.
For high pressure application, centrifugal pumps can be arranged so that it is "staged". An example is the feedwater pump used in a boiler. A three-stage centrifugal pump might be an overkill for ordinary industrial application. Well, I might be wrong as I don't have much knowledge about this.
Meron na ba nakabili nun binebenta na pressure washer na kawasaki brand binebenta sa shoppee and Lazada?
Parang isa lang gumawa ng mga binebenta na Black and decker sa mga ace pero half the price.

Yun me gulong sir. .. i use it for around 3hrs or more pa nga sir.. pero d tuloy -tuloy =)
Basta make sure na yun supply ng water eh available. . ..pag naubusan eh iinit yun motor and it would lead to premature wear.
Malakas naman yun focused na spray nya. . . Yun lang fine(?) na spray nyaeh sana mas madami pa ang lumalabas na water para mas mabilis ang rinsing

RE: Bosch power washer AQT 33-11
FYI
After 1 year of use, the aluminum casing that housed the piston developed a crack. the thickness of the aluminum is thin. Bosch service center did not have the parts.
Am now looking for an alternative brand
I observed those carwash shops, they have this reciprocating pumps run by motors through belt and pulley. I think that one can be repaired. ICE driven washers are a bit of overkill for me, but that one is really "portable" in a sense that you can bring it anywhere as long as there is water supply. Perhaps, after an off-road event and you want to clean up?
Now, if you can collect those broken pressure washers then you can "repair" it by exchanging parts.
Fellow cheapskate hahaha!
Sa province kasi ako nakatira, and I sometimes pass through some muddy streets during the rainy season, so pressure washing the mud off my car is the safest way to remove it. Plus the fun-factor of using a foam cannon is a bonus. During summer, I just use the garden hose to wash, it leaves less droplets to wipe off.
It's also useful in cleaning the driveway of algae (a problem because we have mango trees sa front yard, which I think contributes to algae growth sa concrete driveway).
I can confirm the Bosch AQT 33-11 is _very_ noisy! I've been looking at Lazada, and saw some promising potential replacements:
FASA CELTIC 160 Pressure Washer
Bosch Universal Aquatak 130
I'm leaning towards the FASA washer, as it's cheaper and has more power. I'm just considering the Bosch due to my "investment" in Bosch accessories (lance, pistol, drain cleaner, etc) plus Bosch claims that the newer model is quieter than the old one. Still thinking about it, though, I plan on purchasing one in 1-2 months' time (or when one of them goes on sale)
