Water flow boost

[ma5nasibu]

which is the cheapest and most effective way I can get more pressure from my 750ltr tank (situated in the back of my van) via a water hose to a heavy pressure washer. lifting the washer off the van every time is impractical and when in the van gravity is not supplying enough water despite the tank being raised. need a cheep effective pump. but dont know where to start looking for one
thanks for looking

Machinemart do a range of pumps have a look at www.machinemart.co.uk/shop/categories/search/booster-centrifugal-pumps

Not sure if any of these will work but worth a look.

how much water per minute do you need to feed the washer i think caravan pumps go up to about 12 litres a minute and they run on 12 v electrics youll probably need to wire in a liesure battery via a relay to allow use with out draining the vehicle battery or youll have to keep the van running when using the washer other than that youll need a petrol driven pump
shure and whale are to names that spring to mind google their websites to see if the do larger pumps
i cant see why the tank doesnt feed enough water as i thought preasure washers had a suction effect on the inlet is it possible the feed pipe is to small ?

Thanks for the advice,
@CDs, I checked the websites and got a pretty good idea of how best to try and boost the flow.
@stevetheplumber - this particular kasher washer does not have any suction at all, and the pipe was recomended by the washers dealer.
Thanks for the shure and whale website recomendation
Cheers
