Karcher Professional?

[Turbo]

I'm not keen on any of the karcher or nilfisk pressure washers.
Anything with an Interpump pump, or failing that, an AR pump. Proper metal made for every day use.
... Or a Harben, but its not very practical for little jobs!

I agree that the Interpump is one of the best pumps on the market but there a lot of pumps I would put ahead of an AR.

A work colleague christened them annovi shi77y and it was an apt name. Nearly identical design to the interpump but they use cheap quality materials and components to build their pumps.
The coating on the pistons fails and they corrode. The seals and valves have a shorter service life. They often use alloy cylinder heads that quickly corrode. Trying to remove the valve plugs from an AR alloy cylinder head is a nightmare task.

A pump that is as good if not better than an interpump is a Hawk. They mostly make large pump for industrial applications but they have some small pumps too.

Cat and Speck are a step up in price but you are into proper industrial quality.

Fair enough, i haven't that much experience of AR and just thought they were similar to Interpump in terms of quality and spares availability. Good to know about Hawk too.
Speck pumps are awesome, we use 56/200's for our motive power skids at work. No experience of Cat.

The Karcher HDS 120s from the 1980s was their largest mobile hot washer. Very popular unit across the commercial sector, especially the transport industry.
They were 2 versions of pump fitted, Karchers own design and a Cat pump. The Karcher pump needed regular servicing including seals and valve refacing.
The Cat pump could go for years without needing touched apart from oil changes.
Mind you if you did need to replace anything it was not cheap, Cat service items are quite expensive!

I saw 1 for sale at an auction recently and tried to buy it just for the pump. Unfortunately there were 2 other bidders who wanted it more than me and the price got silly!

I'm not a fan of the AR pumps either, fitted a brand new pump years ago and spent ages trying to get it to run smoothly, ended up fitting an interpump and had no issues after that. I go to service one regularly but that doesn't run smoothly either but its still running. Customer doesn't want to replace it at the moment

We had a HDS 555, it was rubbish. Think it was from around 2000. Very little metal in them by then.
