Anyone know lots about fire engines?
Discussion
Anyone here from the fire service, or know about fire tender pumps?
I need to put some kit together to allow us to pressure test valves and flowlines, using water as a test medium, and a test pressure of up to 5000 psi. There is the potential for quite high volumes, so we will probably need a two-stage pump, high-volume low-pressure crossing over to low-volume high-pressure once we get a few hundred psi reading. The second part isn't particulary a problem as our existing kit could be used to top up the pressure once we get an initial charge, but an all-in-one solution would be preferable. In addition, we need to be mobile as the work is potentially across a few sites.
Can anyone shed some light on whether a used fire engine would be a solution, either partially or fully? Any idea what the pumps are capable of? I know volume won't be a problem, but have no idea what pressure they supply. And if suitable, any sources of used tenders? I Googled, but most of the kit is overseas. Similarly, eBay only returned 3 results.
Any info gratefully received, and a finders fee if you know where I can get the required kit, or can offer an alternative solution.

dont know if it helps but a used water jet cutter? They run up to 30000 psi! Might be worth a try?I need to put some kit together to allow us to pressure test valves and flowlines, using water as a test medium, and a test pressure of up to 5000 psi.

A fire engine 
Not even close a fire engine will get you up to about 150psi
You want a pump skid
Comes in either one part or two parts dependant on size and power. Both parts are normally in a standard road transportable skid.
Normally consists of a big diesel engine through a 5 speed allison automatic transmission which has been converted to manual control. This then drives a positive displacement pump which is run at highish speed to give you the volume and then slowly stroked to get you up to test pressure. 5000psi is easy 10,000 is a normal max pressure wit a few units running up to 15,000psi.
if you want to buy one then try mechserv in arbroath http://www.mechserv.ltd.uk/products_pump-skids.htm... or prior diesels http://www.priordiesel.com/ somewhere in englandshire
To hire one then talk to Q-serv, baker hughs pump services, schulmberger, etc most of whom are up in aberdeen.
If you want more leads, telephone numbers etc drop me a PM

Well, ideally, I'd be looking at a PTO driven triplex pump on a chassis cab. We've used one routinely over several years, but now have a new customer who is looking at a short-term campaign to get certain items into a decent shape before reverting to periodic maintenance. This precludes us spending vast amounts on bespoke kit, as we'd never cover the costs on the rental rates over such a short term. There isn't enough land-based work in the UK to allow us to recoup costs with other customers. Not even close a fire engine will get you up to about 150psi

I work with Q-Serv et al on a regular basis, and know much of their kit, which is primarily for offshore use, and therefore needs to be shipped to site and unloaded. The thinking behind the fire-tender was that we can turn up on site, fully self contained, and carry out our work without the need for craneage, transportation and attendant costs. Got to thonk outside the box!
If a firepump can provide 150 psi, that may well be enough. We have a few high-pressure pumps already, capable of 7500 psi. Once we've got initial pressure, it wouldn't take too much to get to the test pressure. I know of at least one company who used an old Green Goddess for a similar job, although this was 25-odd years ago, when the industry was a different beast.
I think a firepump is more about volume, rather than than pressure. My only experience of a firepump was on an RNLI lifeboat. We had two - a portable petrol one and the main one, which was run off the port engine. The gearbox was unclutched from the engine and the drive to the pump engaged. The pump was then being driven by an 18 litre, 485bhp Caterpillar V8. It could spit out a lot of water!

They were also building an arctic mounted cement unit when i left
