12 volt transfer pump for sprayer

[Turboman]

Will a diesel transfer pump work with agricultural chemicals? Need a 12 volt pump to pump from front mounted tank to rear sprayer. Submersible pump I had has packed up and need a replacement. But might convert to external pump so the wires remain dry. But which pump do I go for , need 25mm ports?

I have a hydraulic pump for sale

Agrochemicals can be corrosive, so something more specialised is needed. Fuel pumps won't have enough lubrication to last long. How much is there to pump and how fast does it need to be? Hydraulically driven centrifugal pumps aren't that expensive. Diaphragm pumps are better and more versatile. Do you need priming or will gravity be enough?

Hi Brisel had a look at your website but they are to slow, really need a pump about 60litres a min. Gravity will work fine , it has to be electric because I don't have any spare hydraulic spool valves

I’d agree with Brisel and say the pump seals and impeller probably won’t be up to it. Not long term anyway. Metal and chemical not a good combo.

If you want a volume 12v/24v pump, with non-reactive plastic internals then I’d look at an AdBlue pump. Designed for handling urea without chemical interaction.

Something like the Suzarra Blue pumps from Piusi perhaps....

 

[Pheasant Surprise]

Something along these lines perhaps...

£189
35 litres/min.

Difficult to find an economic way to shift 60 l/min with a 12v pump.

 

[SimpersTradeCounter]

Can do an 80l/min 12volt diesel transfer pump £295 and it draws 40 amps.

Could you suck from the front tank with your existing sprayer pump? What is not used would be returned to the back tank.

Thinking out loud here, would a 24v pump using an inverter be an option?

Looks a good option in stainless with viton mechanical seals. Would however need to be mounted low as its not self priming.

Consider two of the cheaper pumps in parallel, so you always have one.
But suction pipe from the back would be best ...........

on our first front/rear sprayer combi we had an extra 3cyl diaphram pump on the rear unit driven by a v belt and pulleys off a through shaft on the main pump. just used a diverter valve to agitate/transfer. worked well.

 

[Turboman]

Would it be possible to suck with the back pump and spray at the same time?

 

[Badshot]

If you put a 3 way valve in the suction side of your rear pump you could suck direct ftom the front tank and spray it as you go, the excess would return to the rear tank, or let it dump it in the rear tank, then spray it out.
Think that'd work.

I rarely pumped from front to back, I simply opened valve when back tank was at 50%. Pipe to front was teed direct into rear pump intake so pump sucked from front and rear at same time.
On hills i left valve closed until rear was25%

Pump used more when using front as a clean water tank..

 

[yellow belly]

lely front tank had a 150 litres per min hydraulic pump to transfer
I found that keeping the front tank full till the rear was under 20% full was the best setup for keeping tramlines from rutting and not over loading the rear rowcrop tyres
