 12V electric oil pumps

Howdy,
I recall some dicussion on this a while back (shane?)
Unfortunately Search button = zippo.
I have located a mocal oil pump and another brand (name escapes my just now)on some pommy sites.
see -> http://www.thinkauto.com/oilpumps.htm
Does anyone know where I can locate a similar style electric oil pump in Oz?
I want to transfer oil from the sump to a tank - similar to a dry sump set-up. Just toying with the idea and of course the cost comes into the equation.
Any info appreciated.
Steve

steve ilooked in to this a while back, unfortunately most of the pumps i found were in excess of $1K here in aus, my alternative which i havent put in to practice yet is to imrovise a power steering pump driven off the crank.. for the volume pumped there isnt a lot of parasitic loss, but that depends on your application i guess

Thanks Michael.
I'm contemplating emulating a set-up I saw in a rotary race car a while back. He had a holden red motor oil pump (the external bolt on jobbies) mated to the small drive shaft rotaries have to drive the small oil injection pump to the carby. That was used to scavenge oil from the sump up into a oil resevior that had an oil/air seperator in it as well. The tank would have been about 6 or 7 litre capacity. The bottom of the tank then fed the regular oil pump via a few speed flow style fittings back on the sump.
It worked very well in combating oil surge etc. It is of course a poor mans dry sump system (& I'm poor).
By incorporating this, I can also reduce the depth of the sump (a-la dry sump set-up) which means my engine can sit a bit lower as well.
I'll look into the pwr steer pump (I threw it away 3 weeks ago would you believe ;-(.
Cheers
Steve

you might be able to run an elec fuel pump also...
something cheap and shitty could work.. like a walbro pump 
sure the temps are higher, but the pump is fuel proof... the gerotor ones are effectively an electric oil pump anyway...
they will not probably last as long as a 'proper' pump, and may not like pumping oil foam either (less suction), but it is a poormans way of doing it..
other than that, either holden external pump or PS pump would be easy.. you'd want high volume for scavenging the oil foam?
Cya, Stewart

Steve,
I know that the Holden Astra runs an electric power steering pump. This might be able to be adapted

Astra Yeh?? Very interesting.
I assume that would have to be a late model one??
Many thanks for that!

The Astra that has been out for the last few years (now called the Astra Classic)and I think the brand new one as well-it uses the same engine.
Let us know how you go.

In the Goss catalogue there is a pump that's intended for pumping oil in gearboxes and diffs for cooling - maybe this would be useful?

Shinny,
Is the catalogue on line or do you have a hard copy?

Those gearbox/diff pumps are pretty damn small and are unlikely to flow enough to be useful for this application.

I just used a paper copy at my local parts place. I also figured they'd likely be a bit small, and that the cost could add up once several were purchased...
