Pump struggling

[Mooghy]

I got my self a Shurflo 2095-403-444 Trail King 10 Water Pump-12V/45psi-Silver, Silver, 45 PS of amazon, iv installed it and its connected to my flow control at 80% iv got it connecter via 1/2 inch Garden hose to a 100m long 6mm hose, I get a flow but not as much as I thought it get could the pump be struggling with the pressure from going 1/2 to 6mm should I reduce it to 8mm on the out let first, if I put the pressure ip to 100% the pump over powers and dose a start stop as I'm using it so I'm assuming there's back pressure? Any advice tia

Most people use a 100psi pump, the 45psi ones are normally used in caravans or motorhomes.

Yes as above that pumps not suitable for window cleaning doesn’t give enough pressure

At 10 litres per minute output, it will never work with wfp either @Pjj .

Window cleaners have to understand that Amazon and Ebay aren't the right place (in most cases), to be buying specialist wfp equipment. The best place to buy wfp equipment is a recognized wfp supplier. Shurflo make dozens and dozens of pumps to suit all sorts of applications. The pump you purchased @Mooghy will never work in our application.

Hi Mooghy. I've used a 5lpm 40psi pump on my trolley before, but it only worked because I was using a short length (20m) of reinforced hose 8mm ID hose. When I switched to using the same length (20m) of PU 5mm ID pole hose, the same pump on the same controller setting did the same thing you describe. I think it's called cycling - switching on and off. The only way to stop it was to turn the flow right down but then it was to slow to work with. So I switched the pump to one with the same unrestricted flow rate of 5lpm, but with a higher Pressure (psi) rating. I now use a 100psi pump and it gives me no issues at all, even at full flow if I want it. I usually run it at about 75% flow. Any more is a waste of battery power as it can't force any more water through, it just comes out at a higher pressure which is not particularly helpful and can even be a hindrance.

As the others have said, you need a slower flow rated pump say around 5-6 LPM but higher pressure rating of about 100 PSI

Amazon are normally quite good at taking things back! You might be able to get a refund on the original pump.
