Has anyone used the higher flow pumps. I think they are 6.4 ltr min
-
Yes mate I prefer them, I had shurflo 5.2 lpm and wanted more water at the brush so went down the route of vyair 10 & 8 lpm but they was garbage ...... Did I say garbage I meant $h1te ....
Agratech sell the 6.8 lpm shurflo pumps and they are spot on.

I have a 6.8l but the flow isn't that much higher than the 5l version. I think there's a limit to how fast you can pump water through 100m of microbore, 30' of pole hose and two jets.

I just want that little bit more at the brush. Love a good flow, so I can work faster.
Shame they cost more :)

is it the 8000 543 136 or 138.
Cant tell the difference. Both male 1/2 ports and same output

Shurflo do a higher flow pump around 11lts per minute the problem is they're only around 45/50 psi so not
sure how they would cope forcing it through brush jets.
Ops, Didn't see Duncan's link as said be careful of the psi.

I think 100psi is a must

Have you tried them.
My Shurflo is 3 years old. Told they don't usually last that long. Shows its age at times, but once kickes in :)

The LPM rate is measured at the pump outlet with it working in ideal conditions. As soon as you add a hose and jest the flow to the glass is restricted by these. The lower the hose ID the greater the restriction and back pressure. A higher LPM pump may not result in more water at the glass. Using a control is a more effective way to manage the flow as the pump only produces what is needed at the glass. Rather then trying to force water into a restriction and creating back pressure

I bought a brush from gardiners last week with 4 jets, I reckon this allows more water to flow through the hose quicker, making the job quicker as more water on the glass.
I had 2 identical sections of glass, ( I have my pump rigged up to van battery no controller just switch ) the first one I done with the engine turned off and used just over a quarter of 650l tank, the next section I left the van engine running whilst working and used just over half a tank.
On my normal brush heads with 2 jets the pump runs, cuts out, runs etc etc this is just the pressure switch kicking in, with the 4 jets this don't happen as much and the pump has a continuous purring. When the 4 jets are used and the engine was left running on the van the pump is really beefed up and the flow of water on the brush was very nice to say the least.
I think I will fit 4 jets to every brush
