Oil extraction pumps

Ningaloo · 2 Jun 2022

Just to wrap this up, I purchased the Pela 6000 and was totally amazed at the ease and cleanliness of my last oil change.
I ran the engine to 65C, inserted the (very long) black tube into to dipstick and gave 15 pumps.
Nothing much seemed to happen but eventually the oil started to appear in the container. I got about 1 litre for every pumping session after which the vacuum needed a top up. I found the container stable and was happy to leave it to do its thing while I got on with other jobs. Over about 2 hours (would have been less if I'd topped up the vacuum at shorter intervals) I got 5.5l of oil which is pretty much 100% of stated capacity of my engine. This meant that the filter was almost empty when removed, further minimising the mess.
First time I have ever (in 25+ years) done an oil change without a single drop escaping into the bilge, the floor or me! And instead of the usual swearing, expressions of delight at the whole process.

I have both a 12v and a vacuum type. To me the brand is not important, but I prefer the vacuum version for the silent yet fast operation without needing power supply. A multi purpose tool that takes all sorts (boaty or not) of fluid without risk (hazardous or flammable liquids etc.).

My Nannis are factory fitted with a pipe, connected to the drain plug thread and routed to the top of the engine. 10 mm dia and the thickest nylon tube that came with the pump is the same. A short bit of hose to connect the two and a complete extraction (7½ litres each) can be done in minutes, even of the oil isn't hot.

On the design (Pela ball type vs. cylindric tower), the slimmer tower is better for my engine room.

I have one and it's rubbish. Also not impressed with the Pela. I have yet to find something that is clean quick and trouble free.

I have one and it worked fine for me. The large extraction tube is a good fit for the extraction pipe on the starboard side of my VP D1-20.

Another vote for the Lidl electric pump, so much faster and cleaner than the (6l) pela I used to use. It was ok after I replaced the useless thin suction pipe with a bigger bore one but still took ages and made a bit of a mess every time I had to empty it. Works well for removing water the bilge pump doesn't though.

If I had an electric pump on my boat I would take the time to permanently mount it, plump it directly to the sump (with an isolator valve inline), and ideally also to the gearbox, and a wandering lead for misc. bilge cleanup. A small valve manifold is easy to make.

I have a cheap one from Amazon. The tube is permanently attached to the Volvo sump tube which is cable tied out of the way. I attach the pump for oil change. The trouble is that I can't find an easy place to permanently fit the pump because there is too much removable engine cover. (A good thing for servicing.)

Is there any issue with this tube being open to the air? Will it not just work as an auxiliary sump breather?

Having forgotten to put the dipstick back (dipstick

) My engine was sprayed with oil. Either your tube is quite long, or you are very lucky, if it is open to the atmosphere. Just hope the tube does not get hit by the big end as it rotates, otherwise you may end up with bits of plastic in the sump

The Volvo has a metal tube from the sump to just next to the dipstick. My plastic tube attaches to that. So no plastic in the sump

. And I have about half a metre of it which ends in a coil 10cm above the heat exchanger.

My MD2020 did not have that. I have just fitted a new Volvo d1-30 & that is the same. So I assume that you have a much bigger Volvo. In that case it will be hard work with a small pump. I did have a brass pump, after I dumped the leaky plastic one. Difficult, even with hot oil. I changed to a football shaped tank version, which is a faff but bit better. However, the Volspec engineer who changed my gearbox oil, when it was cold, used a type that had a vertical cylinder. Do not know the make, but it made short work of it.
Edit
Thinking about it- there was a pipe coming off the side of the sump plug. Never thought to look where that went.

I first used a 12V electric pump which was a bit messy then switched to a Pela which was great even for sucking that last bit of water from the deep bilge. When I changed the engine on my last boat I had intended to put a sump connector and metal tube with a fixed electric pump but time got in the way and I forgot about it.

Bought one of the Lidl pumps a few months ago, used it recently for the fist time. Coped admirably with 2 x engines at 20l each and 2 x transmissions at 7l each.

Read, somewhere on this forum, years ago, that they do not last. However, if one keeps the receipt it can be returned within quite a long time scale, so has its advantages

For water in the bilge I have an excellent solution. I have a shower that does not drain to the outlet & the pump was crap anyway. I changed to a whale gulper pump & put a hoselock connector in the suction line
I have a 10ft hose that I canswop into this line & on the end of this hose is a 12 inch length of 8mm copper pipe.
I use it like a wandering hoover hose & it sucks up very small quants of shallow water because the copper pipe is small diameter. I have an 8mm hole in the cockpit floor & i poke the copper pipe through & can suck up tiny amounts of water in the shallow bilge that can cause puddles when the boat heels over.
I also use it in the shower tray to suck up the water that does not go down the proper drain hole.
It can be poked under the engine to collect any water that drips through when I change the impellor etc. I could not get my hand in there with a sponge very easily.
I had a blocked heads & used it to empty the pan then collect some of the effluent as I disconnected the main pipes. The Whale gulper will handle effluent.

DB reminds me of an old trick ... a rubber bung and tube into the bog ... converts it to a really good suction machine for sucking up water etc.

I used my Lidl 12v Oil Pump few weeks back when weather had warmed up a bit ... still cold ! I needed some Lubricity Additive from my containers (I had 5600 litres of it then ,,,, now only about 1000 as another company has been buying it off me) ..
I did not expect the pump to handle the cold fluid ... condition similar to cold lub oil ... but it did. OK - it was not happy - but it worked. In fact it was as fast as my Pela manual job.

I’ve had a Draper branded oil extraction pump/kit for many years and its given very good service.

Quite recently I bought the Lidl version, mainly as a back up. I first used it to extract the oil from the gearbox of a FWD car. Not for the first time that I’ve done this job and it’s nowhere near as easy as extracting oil from the boats Yanmar sump.

The Lidl pump worked but, subjectively, seemed to be struggling a bit so I changed mid way through the job to the Draper and, again subjectively, it seemed to be an improvement.

Not sure now if the performance of these handy pumps has deteriorated by design over the years or if the Draper brand is actually a better product than the no brand/Lidl.

Sounds like you have great parties on your boat

I suppose that "The rubber bung with the tube" is a version of sticking the tail on the donkey

If you run out of "lubricity additive" in the heads, then I am told "K" jelly is the favoured norm

Serious note : Bung and tube is an old way to use the bog as an emergency pump.

....

as to the Lubricity additive ... for increasing the lubricity factor of diesel ... but actually this time - I need something to get a large fire going !! I have had a clear out of old documents etc from house as well as tons of tree branches to get rid of ...

I gathered that. Presumably the bung has to be quite flexible to fit the sides of the recepticle then stick there without constantly popping off, during the opposing stroke of the pump handle. One would expect the pump to draw water in from the inlet first, so one would have to remember to shut that stopcock.
Somehow I think a plastic bailer emptied down the sink would be quicker

It was in the old PBO Sketchbooks ... sadly I've lost mine - had all of them ...

Last summer I bought a brass manual suction pump from F4. I just couldn't get it to work properly. I warmed the oil but I could see it would be a long hard job sucking it out of the dipstick tube so I binned it.

rogerthebodger · 7 Apr 2024

I have one of these with a 2 position valve connected in to the engine oil sump and the gearbox sump for training oil from ASAP works very well using a 5 liter plastic can to collect waste oil

I did at first have one of these with black rubber ends but licked like a colander
