Been having a chat with a very helpful guy called Stephen Goodway at a company called michael smith engineers about a special pump. A triplex diaphragm    NOT PISTON. 
One of the many apparent benefits is that it can run dry without damage and handle small solids in solution without damage.

After enquiring as to what flow rate, psi and drive method I was after he discussed a few options such as diaphragm materials and head materials he said he'll call me in the morning with the plan, the cost and the weight (the body is cast iron)

Anyone seen or had any experience of these pumps before. They look bomb proof.

Guess I'll take that as a NO then :

Had a look at the pump...............fantastic spec', but looks very heavy.

too heavy, too big,  too expensive, too much power draw .... i don't think I've missed anything. if it was possible to use it for carpet cleaning someone would already be using it.

solids in the solution isn't a big problem just use an in-line filter before the pump.

I'm getting mine next month    WHY?
I was looking at a pumptec 1200psi for £400. It weighs in at 60 lbs, draws nearly 1.5 kw an aluminium head and will take woodbridge a lifetime to get it here from the states.

The pump I'm having made is also 1200psi weighs in at 44 lbs, because its powered by a four pole motor it does use up almost 3 kw on startup but then settles down to 1.1 kw, it has a brass head (harder than ally), contains no seals of any description and will be ready 10 days from order.
Downside ... £1150. But hey it different and I'm told I'll never wear it out!

what machine are you fitting it in? from the picture it look huge!

For the mo I'm dropping it in my Ninja. It's something like 20cm x 26cm x 50cm inc. motor.

Think it might go straight through the bottom!!!!!!!!!!great to see someone experimenting, something I used to do years ago, but happy to leave it to a new generation.

Derek at Ashby's is messing around with 1000 psi pump modification to the Ninja. I think he's having a bit of a nightmare though, it's been months now.
But I have a cunning plan
