I have been lazily looking into putting together a pressure washer with variable output that can be split to two operators.

Preferably diesel engined and I would like an output of up to 10000psi. Is this something that could be done and if so are you interested in it as a paying project??. Weight and size are certainly going to be the most important issues.

Rob, a farmer friend of mine built a 4 operator rig 4 years ago, he also sells
them through another company he part owns,  they get all their pumps from Italy.
His is 2500 with 25lts per min, also has heat.
The company he part owns is System Hydraulics Carlisle.
He uses his for cleaning 2 poultry farms, monthly.
Am sure with the right engine and pump it would be possible.

why 10,000psi on a 2 man unit? considering each man will need min 4gl/min this will mean a pump costing £4k and a diesel engine with min 55hp costing another £5k so £9k before you even start getting it mounted.

once you go above 300bar and 25lt/min the pumps go sky high in price

[Steve Gunn]

Now here's a machine that's not pretty but practical now something like that would do me but still seems over complicated

here a pressure washer with 1000bar, and a snip at only £29k

if you are starting from scratch then you will need 6 grand to build a machine with same specification as a 20-22 grand machine sold by the big manufacturers.

if you can weight and get the bits of ebay then you will get this down to 3.5-4 grand

if you look at the for sale section there is a hot box for sale at £450, he will probably take £400. this is the heat sorted straight away..... all you need now is a electric pump and the engine/blower.

American TM's look to be a lot cheaper than ours looking at the Bluebaron.

I already have the hotbox, the requirement is for each operator to have 5000 psi. The 10000psi comes into its own when dealing with drain cleaning but I am not wanting to be operating all of the time at that psi but to have it available would be useful.

Why an electric pump. I would hope to have something self contained, if I went down this route.

On that spec can you tell me what size blower and if electric was not an option what pump (diesel) would you go for.

What about the bit after the blower , vac relief box? tank for waste? Where can they be had from .

Brand new honda 15hp engines 1000

Do you use a flojet type pump ,? , will a 12v one have enough capacity for the flow/pressure needed , if not what pump is needed?

[John Kelly]

Engine say Honda 13 £800 + vat, Blower 36 £1000 + vat Pump 3000psi Hypro £400 + vat Hotbox £1000 + vat Frame to mount on ? Couplings/pulleys/belts £100 + vat Waste tank £800 + vat Fresh tank £144 + vat 12 volt pump £140 + vat hoses/bypasses etc ?
Thats well over 5k if buying new components. Not including fabrication of frame and fitting.

[John Kelly]

Think Gunny was smitten with Paul Kings beast of a machine. Have to say the thing is awesome. Not pretty but pretty awesome.

this is why starting from scratch with your first T/m building your own is not a good idea.  if you are having to buy £800 waste tanks or most of this gumpth then it can get pricey but if you have these already and just need the T/m then it could be an option.

but to be honest if you need to ask how to do it then you don't have the knowledge to start it.

[jasonl]

As I read it , Mike pumps water from the fresh tank straight to the hot box , then onto the wand .

I always thought it an overcomplication to pump to the accumulator, so that the TM engine can then pump to the hx/ wand .

My plan is to mount an electric pump on the van wall , along with a hot box , then have the slideout engine /blower clamped to the van floor , fabrication/powder coating of frame is free if you know the right welder.
Just need the pump spec and to know about the bits after the blower.

Cheers mike , once I have funding I will get this built up .

My brother laughs when I ask if this can be done ,it is so simple , he  laughs even harder at the prices charged by the major manufacturers . He has built waterworks , across the world

Mike can you list all of the components needed and may be if you can take photos and post on here then people can may be have a go.

Personal I'd like just the vacuum system, nice big diesel engine with a nice big vac blower, with ater to go through it like a Prowler.

Shaun

[John Kelly]

Jason you'd be better off running a Hypro pump off the same shaft as the blower. This will draw straight off a water tank as long as its mounted low enough.

Mike its not a case of don't have the knowledge I've stripped jaguars/daimlers down and fully re-built them in my time as a mechanic its mainly sourcing the components,I can fabricate the frame myself. Doing what you did with them prochems machines you bought for parts would be a good start for me sourcing old t/ms for parts but it would be much better if you just sold me yours and you built yourself another one

Paul Kings machine is a beast its probably the most powerful t/m in the country

 Shaun

errr..... OK I'll cancel tomorrows jobs and spend the day taking photos and sat here listing component


Jason as John says you can direct feed the pump but it helps if the watertank is higher than the pump so gravity feed it into the pump, if you have a welder who will work cheap then you can get a plate made so the pump sits on the top but it needs to be adjustable so you can tighten the belt and correctly align the pullys


the biggest problem in self builds  is controlling the heat, it spikes as the burner kicks in but the thermostat doesn't kick in quick enough at the set temp.

steve try and get Paul to post some pictures, I would love to see his machine
