Hi I'm looking to get a second pump.
I have seen 30 psi and they are cheaper than 100 psi.
Does the pump have to be 100 psi?
-
Hi Negativity,
30 psi, dont think it will be powerful enough.
Thats lower than mains tap pressure.
Why dont you plug your hose reel to the mains to get a pressure idea.
Also find out the amp, if its underated it will burn out.
Could cost more in the end!
Stick to the 100psi

80 psi minimum IMAO
-
I would not used a pump under 70 psi( used in many backpacks) as you will even with this pressure pumps, battle to get the water up to 2nd floor windows at the brush head.
-
60 is fine
-
1 psi will push water 2 foot high,.. so a 30psi pump will (just) push water to the top of a 60' pole.
It will struggle though - I'd personally look for a pump with a slightly higher rating.
Flow rate is more important than PSI - for wfp you want a pump that kicks out between 4 & 5 liters a min,.. obviously this is then adjusted down with the electronic flow controller.

Thanks
Anyone in West Yorkshire got a pump for sale 100 psi preferably?

70 psi in my backpack can clean at 35ft with plenty flow at brush easily.

I know a guy that uses a 30 (maybe 40) psi from john hewitt.
It pushes through 100m of hose and a 25ft pole just fine to be honest, and theres no need for a flow controller as the flow seems to be good enough to clean with....
I think it would struggle through more hose though, or a taller pole
-
Having used the high flow(12 litres per min) low pressure (30PSI) pumps i can tell you they are fine for ground floor and 1st floor. Once you get them above about 25 feet high the flow becomes intermittent as the pump struggles with the pressure.
-
60 psi is fine if you want a cheap pump there's a company on the web called all clean group

it's actually the full clean centre £30 for a 80 psi pump thats cheap
-
Im not saying go for 30psi pump but my shurflo backup pump was 35psi and its still going strong now, had it 5 years i think and its had some hammer, it even works up to 60ft high with a good flow, and thats not flat out.

been using 70lpsi 2.6lpm for last two yrs and gets to3rd-4floors
easily

they have both shurflow and flojet pumps in stock . also do 2nd hand pumps , poles, tanks ect .

Imao??
Im thick sorry
-
30 psi might work in a backpack but if your van mount with 100m of hose it may struggle because of all the extra friction it needs to overcome.
-
i would just stick with 100psi pumps if i were you.they are not expensive!if your using 40 or 50ft poles cleaning solar panels or windows you want a good flow.
-

Wrong sorry, this is how i use mine with 50m on it, and i have used it with 100m.

That's a tidy looking job could I ask how much it cost to put it
together.

Thanks, £20 for trolley, £20 reel which i attached with jubilee clips and i had hose lieing about. :)

That's good to hear but if your going to use 100m of hose it sort of defeats the point of a trolley surely?

30psi is fine through 100m of hose we've used it with both 6mm and 8mm hose. Only issues where getting water to flow out at height i.e over that blackspot about 25 footish. PSI actually can work out to metre head and some pumps are quoted as this. Without going through all the jargon you can work out how high a pump can squirt water by its metre head figure (or equivalent PSI). Of course as you point out longer hose runs will mean the pump will have to work a bit harder, but they're still well able for two storeys using the setups we do.

I did all this in college but I can't remember all the calculations involved. ;D
I'm an engineer by trade and I'd always go for the more powerful pump from a reliability stand point.

Yeah you're probably right. We only got to try out the 30PSI ones for WFP because we had got some to supply jet washers and other stuff from our water tanks and then just tried them. We do have one in daily use. We got a pleasant suprise.
-
yer u need a 100psi imo
-
Too much pressure just puts extra strain on your connections, drains more batter power & can cause hoses to bulge if you use hot water. I have a 100psi pump, but have adjusted the pressure switch down to 60 PSI. ;)

How much you want for the pump?
I'm 17 miles away and it's quite a nice drive except for some parts of Darton ;D ;D ;D ;D

Theres 50m on it now...its great to pull trolley up and you can literally get anywhere with it, trolleys can go most places and if it cant i just pull reel off.
I have a twin van mount and this for those awkward jobs.

Your trolley looks both simple and practical, can I ask you where the pump/battery is on the trolley? ???

Ok, ic, good way to do it, but possibly a bit hard on the back if you are doing it day in day out. :-\
