electric power steering pump pressure (Saxo, Xsara etc)
Does anyone know the max pressure derived by an electric hydraulic power steering pump as fitted to some saxo's/xsara's/106's/307's etc?
I'm in need of a 12v pump which can make upto around 110psi

Right, so it shall remain a secret then Vanny Not an electric LHM pump then? If that were the case, you might be better off with an electric HP pump from a C5. It should be OK if you want to pump LHM with it.
Getting back to your original question, I believe these electric PAS pumps have been used to replace a normal engine driven PAS pump by some. 205GTi owners doing Mi16 conversions I seem to remember using them to keep thier PAS going but why anyone fels the need of PAS on a 205 is beyond me
Some Vauxhalls I believe also used an electric PAS pump.
Anyway, I digress. What about driving the engine driven pump with an electric motor?

jim, it is in order to power a hydraulic LHM system. C5 pump was considered for all of 30 seconds until i realised that a) there expensive b) there not common in scrap yards yet.
Saxo pump seems the best bet as its easy to connect up (with rubber pipes, no need for complicated BSP connectors), i've considered driving regular pumps from an electric motor, but that means more space, more complexity, greater losses of power through transmission and probably an over sized unit that does a LOT more than it really needs to. A nice little PAS pump would be ideal as it is small, compact, 12v, will run on LHM happily, more than enough thru put BUT will it produce enough pressure, i total expect that it would but would like to be reassured!

That's the worry Vanny. A true HP pump will go up to 170 odd bars and I reckon any electric PAS pump will struggle at that sort of pressure. Only one way to find out..
So you're planning a cunning anti-sink BX then? Run the pump every hour or so to keep it at ride height
Or is it a fix for Toddao's rapidly sinking BX?
Or are you creating an electric sphere tester?

I was thinking recently about being stuck in the back end of no where in a broken LHM car.... the un-towability is a pain really... a temporary way of getting LHM pressure would be a good addition to the toolkit..
Someone even told me planes have small wind operated pumps that drop out from wings, to power all the hydraulics when a plane's engines stop
edit..
I suppose taking the injectors or plugs out would help..

Here's a thought.
The Pug 405 4WD estate has hydraulic rear suspension, spheres and all but only on the rear.
Would the pump from one of these do what you want???
To run a standard LHM pump from electric will take a lot of power, out test rigs in our workshop are electric and to get the system up to 175- will make a motor grunt a bit unless it is a realy powerfull one.
You can run a standard pump from an old starter motor, but these use a lot of power and are only designed for short busts of use.

Martin.

Here's another thought!
After reading your first post properly I have realised that you want to produce 110 psi.
The Citroen hydraulic system runs at 175- max, this is equal to about 1'750 psi
The standard power steering (belt driven pump) runs at about 60- (approx 870 psi)
I would have thought that the electric system would be the same (ish)
What excactly are you planning? or is it a tip top secret mission?
I do know a bit about hydraulics and may be able to suggest something if I knew what you were up to.

Try a 305D PeterN....Have you driven a 205 diesel Jim? My mother had one and developed quite substantial arm muscles. When I brought it home I nearly drove straight across a roundabout.

I've owned a non-PAS 205D, a 205D with PAS and a non-PAS 205GTi.
The non-PAS 205D had, to me, very pleasant steering, the PAS 205D is (my Dad still runs it), by my reckoning, far too light and the GTi at parking speeds was a little heavy but at speed, really rather good, steering weight-wise.
That's me and I'll freely admit to having plenty of upper body strength and my definition of light steering is not anyone elses. My Dad often compains his PAS 205D is heavy on the steering... So, in short, take no notice of what I say about steering weight
Is it me or is the steering on the FDV-equipped (very early) Xantias MUCH lighter than the steering on anti-sink Xantias with the 6+2 pump? My old 1.9TD seems so, so light in comparason to the 2.1TD and Activas.
I can't blame wider tyres as the 1.9TD wears 195s on alloy rims and I can't imagine those and the 205s on the 2.1 and Activa would have a huge effect on steering weight..
