Thanks a lot
Do you know which Karcher model have aluminium pumpe, because I heard that there is models with plastic one
![]()
unfortunately they don´t show which models have a plastic pump or aluminium pump....i have to research that first.....
the easiest would be to buy a Kränzle pressure washer since all of them have a drop forged brass pump housing and stainless steel valves ......
edit:
this is the lowest price Kärcher with aluminium pump it seems:

edit edit:
the Kärcher "K2" + "K3" + "K4" series washer have a "N-Cor" pump from "Polyfiber" plastic....
the "K5" and "K6" series have a alu pump and the "K7" has a brass pump
edit: edit: edit:
this special model has a alu pump too:

so the pump qualities are:
Plastic = junk
Alu = better
Brass = best
