Re: ~9 bar volumetric 12v pump for a commercial machine?

I'd invest in a generator instead - has many uses and by the time you got done finding for a new 12V pump or motor and adapting it you'd spend the same amount. If you have electricity on site you can do a lot of things - lighting, grinder, other appliances, etc.

Or get a propane heated lever machine and skip electricity completely.


Not really doable. You still need some power for the inlet pump, autofill etc, plus grinder etc.

A colleague runs an inverter off two 24v lorry batteries to power his 2 group semi auto with propane kit, grinder etc, and charges the batteries once weekly.

The standard 12v pump I referred to in my earlier post is fine for providing machines with mains pressure inlet water, the machine does the rest. They are rated for at least 12 l/min.
