Oil Sump Pumps

[Little Dorrit]

Are the £15 ones on Amazon any good? I have about 3.5 lures to remove from a Bukh DV24 and need to extract the oil through the dipstick. I would prefer not to have to remove it completely so was hoping I could use an electric oil sump pump and pass a tube down the dipstick holder tube to make the job easier and cleaner. Has anyone any experience of using the electric ones or is there another better way of draining the oil?

Mine is a £10 Chinese one. Does a good job

I’ve had a Draper 12v oil extractor for many years. It’s given me good service. I’ve extracted oil via the dip stick on a Volvo MD2030 and, for the last 10 years, my Yanmar 3JHE. I’ve also used it to remove the oil from the gearbox of a car. I have a boxed, unused £10 Lidl version as a back-up, too. The cheap one looks pretty much identical to the Draper.

Warm the oil before removing it. On the Yanmar, the pump pulls the oil by creating a vacuum. On a car gearbox, it’s by wiggling a pipe around the bottom of the gears.

Discussed here before.

Most people are happy with the vacuum, no power, silent type. Various capacities, commonly some 6 litres.

One brand is Pela - several alternatives around. Google "oil suction pump" and see

The electric pumps are cheaper than a vacuum pump . But having watched a couple of videos on youtube I am not convinced they are better than a vacuum pump which has tues inserted down the dipstick into the sump.

But an electric or a vacuum pump pays for itself on a single use compared to paying someone to do it.

I have used my vacuum pump for a few jobs other than engine oil change . eg. pumped out bilge water after a domestic water leak . A useful tool to own.

There might be individual deciding factors also. If 12v is not available or there is no space for a vacuum extractor with its integrated tank...

Have used various clone budget 12v pumps to remove oil from various Mobo engines. Lead usually long enough to reach batteries.

Takes around 10-15 mins to pump out 11 litres of oil from each Mobo engine.
Do now that a similar pump has been used to shift 40 litres from much larger engines.
Just connect and walk away.
Pump directly into your choosen final container , in our case a couple of old 20L drums no messing and then down to your recycling yard.
No messy transferring oil from vacuum pump into secondary container for disposal.
Job done more quickly and efficiently if engine oil is fully up to max temperature.

thanks for the replies, I'll try the electric one. Although I can see the advantage of the manual Pela type I'm not sure it will be used for anything other than oil extraction so I'll save a few quid and get a cheapo one.

I use a Pela on my Buhk 20, but i remove the dipstick tube first so you can get the larger size pela pipe into the sump. It does work with using the smaller diameter pipe through the dipostick tube but even with the oil hot it is a very slow process.

I change some 7½ litres per engine with a Pela type (different brand).

Commonly takes a beer's time each

They can be useful for extracting liquids from other awkward places as well. When I changed the heads pipework, I used my Pela pump to extract standing water in the low points of the pipework to prevent the contents being discharged into the bilge.

I use a Pela pump on my Volvo TAMD41P engine. I believe it holds 11 litres but I never get more than 6 or 7 litres out. Do I try to find a longer extraction pipe or has anyone found another solution?

 

[Little Dorrit]

Now I am not sure, I may get a manual one, they do a 4 Litre manual pumps on Amazo for around £20.

Safety: The vacuum pump, working only by you pumping, is safe for petrol and other inflammable - a 12v driven thing would need to be double insulated and approved for it to be safe.

A big advantage of an electric one is being able to pump oil from a bottle into a hard to get to item like a gearbox.

I bought a 12v oil and diesel pump from Lidl for I think £9.99 a couple of weeks ago.

On the Yanmar the dipstick goes inside a built in tube which goes right to the bottom of the sump. Rather than using a thin flex tube down the pipe I use a fatter plastic one which just goes inside the collar on top of the dipstick tube area. I seal round this , including the tiny breather hole near the top collar bottom , with self amalgamating tape. This speeds up the job no end as you are drawing through a much bigger diameter. It may be the same on your bukh.

We empty every drop of water from our bilges with Pela.... I like our bilges nice and dry if possible, plus Pela is great to drain oil from the engine

On the VP TAMD41P the dipstick tube goes almost to the bottom of the sump so i use one of these
Sealey Drill Powered Water Pump 1000 Litre / Hour Drill Powered Pump TP51 5024209040594 | eBay with my Makita drill using 1/2 inch hose clipped over the outside of the top of the dipstick tube. Only takes a few minutes with hot oil due to the larger bore size compared with a pela. I get about 8 litres out. No idea if some is left behind or if the quoted capacity is wrong.
