Gear pumps - Which one?

[Tony From West Oz]

I am looking for a gear pump to transfer oil and biodiesel in my fuel processing area.
It should be 240V operated and have an over-pressure bypass to prevent hose damage if dead headed.

I saw this one on Ebay: http://www.ebay.com.au/itm/Heavy-Dut...wAAOSwr7ZW3sr2

Does anyone have any experience with this pump?

Any other pump that you would recommend?

My existing fuel transfer pump sucked up some byproduct and now it does not pump anything. The vanes are damaged. Is there a supplier of replacement parts for these? Unfortunately, I do not have the ebay item as it was purchased about 5 years ago.

That one looks like the pump is made of plastic or poly. I'd be looking for a brass pump myself. Is it even an actual gear pump?

I might be wrong here, but looking at the photo up close it shows the typical 'dimples' of a cast housing to the pump section.

but by the location of the input port, I would think it was a vane pump rather than a gear pump, as in my experience gear pumps have their input and output ports located centrally on the housing as they feed straight onto the face of the gears where they mesh so the fluid is shared evenly across both gears.

on the other hand it might just have some funky internal gallery.

I use a brass gear pump with hemp seals. dead simple and nothing to go wrong. powered by an old washing machine motor via pulley and belt. The one pump pushes everything for me, oil into mixer, and fuel out of mixer into storage tanks. if the mixer stirrer fails on me for whatever reason, I can just flick some valves and mix the brew with the gear pump just like the other guys here. best of both worlds. pumps 200 Litres in just a few minutes.

go the old school brass gear pump every day.

That was what I was looking for, but hard to find.
