Title: 10L vs 6L pumps fao alex
Post by: chanster00 on December 18, 2014, 10:07:09 pm
can anyone help me? going to order a vyair 10L pump tomorrow. can anyone tell me why i shouldn't?

all pumps are the same price but this ones a 10L wanna know if this ones a good robust reliable one!
iive got 3 "aquatic" pumps all great! still working no probs! been told 10L is amazing though to speed up work

If you need more water than the 6l pump can supply then you will need the 10l pump. However it may be that other specifications have changed along with the flow rate - often current draw, operating temperature, motor spin speed will all vary to achieve the higher flow rate. Whether this will make it more or less reliable, time would tell - although the Vyair supplier should be able to advise on the effect that increasing the pumping speed will have on the longevity of the pump.

alex

do you  also advise that using a better flow will help with working at higher speeds while getting better results?
regarding the robustness! ill just have to see i guess! id never ever buy a shuffle again!

We've just upgraded to a Vyair 10 litre pump. Makes a big difference IMO. Faster rinsing for sure.

I get 140amp battery to supply the power

one more question, fan jets or pencil........dying to try fan jets out

We use 4L pumps in all the vans... on fan jets and 70AH batteries. No problems will run for 2 days on one charge.

Hi chanster00

I do advise a higher flow rate as your speed of work can increase. I use a 6L Aquatec pump and have the digital Liquid Logic flow controller set on about 75 flow rate. I find I can work faster and use no more water at the end of the day because of working the glass faster. I do use a pole flow control valve so as not to waste water between windows.

try em out
My gardiners brush has two sets of holes so I run both 1.4mm jets and fan jets but not at same time. I switch between them depending on type of job I'm doing and whichever works best.

In some cases a higher LPM pump may draw less current although there are a number of variables to take into account,as Alex has already mentioned.

It is worth taking into account the effect of the hose, hose run and jets on the actual amount of water that hits the glass. This article looks at some of the points http://www.springltd.co/node/137

Their is evidence that suggests a higher volume of slow moving water will help in terms of time taken to rinse the glass in particular Hydrophobic glass.

On the Converse side the higher the LPM the greater the back pressure can be so it is always a balance between the two.
This pressure dynamics link covers in a little more detail. http://www.springltd.co/node/138

Higher back pressure is likely to cause the pump to work harder and draw more current so again some experimentation will be needed to find the right balance for your system.

A controller can make a big difference to the efficiency of the system as the ability to vary flow to suit the job means the pump is only ever producing the water required at any time. The only limitation with the control in terms of pumps is that the pump does not exceed 10 amps which is the maximum rating of the controllers. Other than this the flexibility of the control means it will run any pump up to 150PSI and rated below 10 amp.

A combination of a tap and controller works well as the tap can act as a water saving device as you move around a building, while the control will DE the pump well before the pressure switch cuts in helping to protect the system and pump from excessive pressure plus all the protection features of the control.

What I personally find very interesting is that the more I learn from you all, and the better I understand what is happening the less I know. Each bit of research opens up new questions as to how and why. WFP is a continually evolving place full of innovation. For me that makes it fascinating to be part of.

I have used the 7 lit and the 10 lit pumps they re defo faster to clean as you will not have to chase the stream down the glass, dirt just runs off. These pumps do not make a big difference with fan jets but with pencil jets they are impressive, The 10 lit I find very good on nearly flat conservatory roves.  I have 10  flat roves to do each month its made the job very easy. I find on normal clean, you can turn the controller down. I don`t find I have used more water or battery amps  even though the do draw much more amps.You will clean for less time. I don`t understand water saving as its pure that cleans the glass and as far a spotting goes its not  factor in my days work. My 7 liter per min is 3 years old and my 10 liters is 6 months ,I have spent 2 pressure switches on the 7lit and one on the 10. I would advise keeping a spare pressure switch in you spares as they go with out warning but easy  change. You do have a 1 year on the pump and Vi air will replace but its the time. The rest of the pump is bullet proof.

Slap bash great response exactly the areas I wantted covered! Am using a controller anyhow so the pressure switch part should be ok.

Thanks for that reply

I've Been using the sureflow 150 psi pump quite a while now, it's flow rates not that Much higer, but the pressure  behind means I can attain higher flow rate on lower settings been very happy.
I dont use more water really but if I want bigger oomph it's there, I do have to higher the calibration on the controller to balance dead end but not much a problem

Best thing I've changed

I have always wanted a pump with extra flow power. I can run my controller at 25% and still have very good flow with the plenty reserve if needed. Happy to help.
