thanks for the info guys. i ran the pump today and it seems to be working ok  so time will tell the customer service is second to none from that place so no problems with that.

Hi Dave
Please can you tell me what the make and model of the pump is now you have it. There must be a spec sheet on the net somewhere. The spec Vyair puts up on the website is a current draw of 3amps, but despite asking twice, I haven't received any further info from them as that seems a little low to me.
According to Shurflo, the pumps I have always used, their pumps draw 2.3amps at 0 psi and 6.2amps at 100 psi.
If the Vyair only draws 3 amps at 100 psi then the battery will last longer.
Thanks

Hi mate the 3amp draw is at 100psi from what i have been told by the company . the volts drop down by 0.4 when turned on at full power so from what i can make of it. it uses s very little if you need any more info i will try and help out as much as i can

Dave


PS the make of the pump is E-CHEN

Hi Dave
Interesting as the 7 lpm pump draws 8 amps and it looks to be the same pump.
Thanks for your help - I will try to find something more on that.

Hi spruce the 7l pump is also a 3 amp draw same as the 5l. the amp draw starts to rise above the 7l these are the details


5lt 3 amp
7lt 3amp
7lt 8amp
10lt 8amp
12lt 8amp

 that's what i found out Dave

Hi Dave,

Thanks.

I see on the manufacturers website they don't list a 12vdc pump. The specs for an EC-RV-05L 24vdc pump are:
0 psi     5 lpm      1.9 amps
10psi    4 lpm      2.2 amps
20psi    3 lpm      2.6 amps
30psi    2 lpm      2.9 amps
40psi    1.5 lpm   3.4 amps 

If this was a 12vdc pump then the amperage draw would double.

Also not sure what they have done differently to increase flow at the higher pressure of 100 psi! Prehaps it not the same pump but I can't find anything else.

I was tempted to look at something cheaper, but my gut feel says that I should stay with Shurflo.

30psi    2 lpm      2.9 amps

That is what i've been looking for.

For one man setup,no need for a flow controller or valve.

12v pump would draw 5.8 amps which is quite a high current draw (pump spec is for 24vdc). The pump has a pressure switch set for 80psi on - 100psi off. It doesn't look as though it is adjustable. Whilst I understand what you want to achieve, I'm not sure if you will be able to do it in practice.
When testing the pump, they will start a 0 psi and see the amp draw under those conditions. They will then restrict that pipe to record a pump line pressure and see what the motor draws at that pressure to the restrictor. The trouble is you have to calculate how to duplicate that same pressure but with additional restrictions such as hose length , brush jets and height of work surface.
Got to be an electronic controller IMHO
