Shurflo 30Psi Pump

[TobySampson]

I never run my 100psi pump on full and saw some 30psi pumps on eBay.

Question is.. Would they work with a 100m hose like the 100psi does?

What pressure do you think you run your current pump at? If this would work it would elimate the need for a flow controler just on off. What's your thoughts?

Personally I can’t' see it being much good to be honest as the pump will be running flat out all the time. Think at that price £59.99 for a 30 psi I still would still pay a bit more and go for a 5 lpm 100 psi shurflow pump.

The main reason that a 5 lpm 100 psi shurflow pump is the industry standard pump to use for wfp work is its reliability and longevity. Most wfp window cleaners including myself run the pump under half its flow rate capabilities so in doing so the pump lasts longer when using a pump controller. Also has the advantage of using a variable flow rate when required for instance when cleaning taller buildings.

Hope this helps?

I've got a mate who can get them trade price at £30... I might get one as a second pump so someone can do bottoms while I do tops. What do ya think?

 

[Smurf]

At only £30 then worth a try at that price I guess.

But for me I would still go for a better pump and controller myself for a 2 man setup as would give a whole lot more flexibility.

True, I suppose buy the best you can afford then you won't be replacing as often.

7 litres per minute is too high a flow rate. It would just 'cycle'. I would also expect that 30 psi wouldn't push much water through 100 meters of our hose.

What that pump would be ok for is transferring water from a van mount to a trolley or backpack, but gravity would probably work just as fast and cost a lot less.

30psi isnt powerful at all to be honest

How high do you have your water then do ya think?

What does cycle mean?

i have 100 psi pump and run it at 45 on my pump controller.

 

[Smurf]

Depends what I'm cleaning to be honest what flow rate I choose also if I'm using hot water or not as the portable gas water heater I've got doesn't like a lower flow rate like 30 as will keep turning itself off.

i run my flow rate on 45 aswell lol but put it on 40 when am a bit tight lol , on first cleans i will put it up to around 80 /emoticons/smile.png
