Minimum PSI for a WFP pump
« on: June 27, 2013, 08:41:28 am »
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

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.

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.

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
Why don't you have a quick google before making stupid comments?

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.

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.

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.
price higher/work harder!

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