Positive displacement oil transfer pump.

[Grizzly]

I have finally been given permission to purchase a decent Oil transfer pump.
Preferably 110v.
Can anyone advise as to a suitable one and where to purchase said pump?


Thanks Guys.

Please check my posts history, I have posted my oil pump details, If you dont find it, I will post it again on Sunday when I return home.

Grizzly,
We generally use a little Viking oil pump & select it for 10 to 15 litres a minute for 1/2" hoses.
It comes on a mounting base with motor & you can select any motor you like.
I think JCI can supply at a very good price as its what is used on Frick screws.

Hi Grizzly,
I had mine made by Danfoss hydraulics, with bypass reg., discharge check vav and gauge. Italian pump, Salami. [as in sausage ] takes about 30 min to empty a 205 litre drum into a discharge oil sep at standing pressure.
How have you managed with out one up untill now ?.

Apprentices maybe!

Tutil do a neat little unit 1/2" connections for about £900 ish

Its called VISCOMAT 70 and you can find all the details here: http://www.flowfitonline.com/acatalo...PUMPS_480.html

Thanks for all the input Guys.
Chemi £465 may be somewhat cheaper than Quality's price.
Thanks for the link.
I have found this one via google.

That is somewhat cheaper although it is 240v. I will have to dig deeper.

Ranger thanks for the heads up on the Frick pump details.
I may be able to do something there as I know we get favorable JCI rates, their prices are still scary though!

Hi Magoo I did not know Danfoss Hydraulics existed, well in the U.K.anyway.

In answer to your question I have been able to borrow one made up from a Lamborghini Hydraulic pump. The type you find on doc levelers, a brilliant bit of kit!
But Thursday for the last time as far as I am concerned I did not have the opportunity to borrow said pump and spent 13hrs of a 19hr day.
Doing a oil and filter change on a Grasso screw pack (Ammonia) I ended up pulling a vac to -.8 bar and sucking the oil in.
The alternative pump I took was useless and I gave up on the stirrup pump (No apprentice available Ranger!)
So at the post job debrief it was agreed that a suitable pump should be sourced.
Hence my post.

I will let you all know how I get on as I like many am restricted usually to who is on the suppliers list.

Try applied pumps in Chesterfield they can supply any oil pump like the one I suggested at reasonable prices £300 circa

You just need a bit of nitrogen to push the oil out of the drum into the comp set. With a regulator of course

Done this myself and ran out of oil !

[Grizzly]

Thanks Mad fridgie!
But I intend to get a pump, its a lot less kit to carry plus more controllable as Quality points out!
Thanks for the heads up Quality.
The vacuum method is fine just so time consuming, whereas being able to push against system pressure does have its merits.

Hi MF.
not so good an idea when refilling a screw separator with 200 plus litres with standing pressure of 8 bar, the drum gets very roundish looking, would not recommend.
I had a client that drained fairly saturate oil from an oil trap [ ammonia ] next morning drum looked like a keg with oval ends, actually fell over due to roundness. I got him to crack the cap, he never did it again to save a service call

Hi had presumed, that the system was empty of pressure. and could just get him of of trouble in the short term.

I made small pressure drum with 2 valve on it ( bottom and top ) and one 30mm screwed nut on that to fill oil .
I fill oil as much as I want then vacuum it and from discharge of compressor (top valve) I pressurize drum and from bottom side valve oil goes to suction of compressor.

MBC.
Thanks for your kind advice.
What you describe and to a degree what Madfridgie describes is what I would do / make-up if I were site based.
However as a mobile engineer just having a pump is what is needed.
Given that the quantities as mentioned by Magoo are in the 100's of litres. Therefore there is to great a risk of cross contamination using the nitrogen.
On a part isolated system you cannot go using Nitrogen and once your drum has purged itself of oil MBC.
What do you do with the vapour that has replaced it? Given the number of drums of oil involved, it's a non starter really.
In fairness to both of you, in the correct circumstances either option would be a good one and I thank you for that!

grizzly, i have an idea for you, there are small hydraulic pumps used on farm machinery, plastic injection machines, etc. these are high capacity and can work against high pressure, all you need is a pump and a small electric motor, about 1 - 1.5 hp and you got a cheap good pump.

On the other hand, any hydraulic motor, can be used as a pump if you connect an electric motor on the shaft.

Just a thought....hydraulic-motors.jpg

Thanks Guys.

Definitely, the best for me is Sabroe oil transfer pump ... very useful with many different pipe connections .... left&right rotation, check valves ....

you would like it.... ... price is another story ... sorry ... do not know about ...


Best regards, Josip

hi grizzly i use a old york j body oil pump , what ive done is drilled and taped the discharge hole to 1/4 npt and suction to 1/4 npt and put in a normal 1/2 inch hose on suction and a 3/8 flare on discharge with a nrv in line and i use drill to spin it it primes it self and can pump from 46 to 220 grade oil easy, the only thing is it drips oil at the tang but only a little bit,
