Probably more cost effective to install a circuit from the consumer unit, or suitable spur point, thank buy batteries, inverters etc and the manual handling of said items.

I assure you trenching in 75m of armoured cable is not cheaper and easier than buying a battery and inverter

if it were me, i would bodge up a 14.4v Li-ion battery and use that to power the inverter, a lot lighter to carry
does the little motor have a data plate, i didnt see the power rating mentioned previously?

Yes, you're on the money, a little single bucket milker with old motor and ancient alfa-laval pump

This was before i collected it


Internals were rusted and seized



Refurbed it, unfortunately two of the carbon vanes need replacing




Can you see a model no.anywhere on the vac pump ?   9M ,  18M ??
Probably obsolete but am in depot on sat will look for parts list / vanes .

It is indeed a 9M - no parts available.

I could find nothing about that unit anywhere, but you may find pump vanes here:

http://carbosystem.com/en/vane-for-pumps/

I think this lot are in Spain. If they don't have the part, they may be able to supply a similar part that can be bodgineered to work. If given the dimensions and a photo of the vanes they may be willing to send a couple of samples.  Wink

She comes into the crush ready enough but she doesn't let down her milk for me.

It's alfa-laval, when I spoke to them they told me they sold the dairy side off to Delaval


She wont let down for you with the calf around. You are stealing its food.

You need to become the calf.

If i take the calf off 24/7 rather than 12/7 then i have to bucket feed the blighter!
This way i get milk and she feeds him

Do you mean build a bank from new cells?
Because i can't see how a re-purposed cordless drill battery would have enough capacity? They only go up to about 6Ah and they're expensive.
I don't intend to carry it either, the trolley will take it,the motor/pump and milking bucket

Any amount of current can be gotten from any battery.  Just need more paralleled groups (of 4 cells in series, charged to 3.7V/cell, for 14.4V nominal) in the case of lithium ion technology.  Most battery screwdrivers/drills donít have half horse power motors - but some do (usually the higher voltage ones).

There's a mains supply there, it's the easiest way to go, even 2.5mm2 will be fine for volt drop.

Duct it in, lay it surface in a duct as required.

If power wasn't available then consider batteries etc.

2.5mm SWA cable is less than £1/metre so probably cheaper just to buy it, bury it and fit an exterior rated socket and at least you know it will work when you need it (power cuts excepted).
