Hand oil pumps
I'm looking to get a hand oil pump that can pump good volumes of oil against pressure but all I have seen from the fridgy wholesalers is the likes of the Refco or Yellow Jacket hand pumps that can pump against pressure but can't pump the volumes. We have a good electric pump but it's not always handy.
What do you folks use?

Re: Hand oil pumps
I use on large compressors and oil reservoirs an electric oil pump.
I can only get the details tomorrow.

Re: Hand oil pumps
You could suck some oil into a clean recovery cylinder, vac it out then used the system discharge pressure to push it out again.
I think the pressure you need to be able to pump against with a hand pump limits the volume pet stoke, one with a high volume would need your whole body weight behind it to move any oil, hence the low 50ml per stroke of the refco pump.Mostly found in Oxfordshire, UK :)

Re: Hand oil pumps
shut suction and discharge valves and vac out the compressor body only and then use a normal hand pump and the oil will flow a lot better. also get a boy to pump it instead

Shut the compressor valves, vac out the compressor to 0 psi/bar.
Connect your oil line to the compressor, run vac pump and suck the oil into the compressor.Brian - Newton Abbot, Devon, UK

Re: Hand oil pumps
Thanks for the replys.
I will check out the possiblity of a small gear pump that could run off a electric drill or the like. Had a look at some of the hydrolic outfits recently with out any luck.

Hi Superfridge.
My electric pump was supplied by Danfoss Hydraulics in Mt Wellington The size of an average vac pump.
