Strange Pump

Trying to find the wee brass hand pump that I use to pump the sump oil out of the dip stick hole. Couldn't find it on the usual chandler sites so Googled 'Brass Hand Pump'. Found this site

How to size your pump

Well, I'll gu' 't foot on are stairs!

I was thinking of purchasing a sump pump too, only today. Though the pumps on the site could well be adapted to do the job, they do look a bit pricey.

'appen a sump pump could be adapted to perform other functions too, I don't fancy running me Volvo on KY jelly though.

Best pump is the one where the pump is fitted inside the sphere which also holds the waste oil, or what ever is been pumped out.
Cant remember the name of it, but Duncan's yacht chandlers sell them at a reasonable price.
Certainly no mess with them, Sealy tools do a bigger one which is cylinderical in shape.
I had a loan of the latter type from a friend to change the engine oil, it is a really handy peice of kit.

Found it. You don't need to worry about following this link

The only reason that I started looking for one was because I had been telling Aquaplane that I used mine to draw a diesel sample from the bottom of my fuel tank.

I think the Pella is one type, there are several of these combined extraction and storage systems available. The problem is you still have to empty the container into something disposable.
I've had a variety of sump pumping systems on my various boats but by far the best was on the Perkins 4108 in my 41' ketch. It was an electric pump mounted inside the engine compartment and permanently piped to the sump. I held an empty milk carton or other container under the pump outlet, pressed the button and it did the business. It made what had previously been a pain in the arse into a simple, clean, operation.

Yes John a permenant pump is a great idea, but tho point you mention about milk container is where the chances of making a mess between filling it and disposing of its contents,, come into the equation,( Nick, you know all about that, dont you? )
With the Pella for instance its pumped, contained and transported with the minimal risk of spillage, even if it has to be emptied outwith the boat and a second pump out has to be done.
Incidently I am almost certain the pump at Duncan's is a Seago, probably made by Pella or someone else.

For sampling diesel I did consider using a 50ml syringe. The trouble with syringes is the leuer adapter on the end, they are a bit thin for large quantities of thick oil, OK for diesel though.

I was looking for a brass jobbie for the oil change.

Why not adapt a plastic bicycle pump by alerting the piston and fitting a more rigid suction pipe.

Whichever pump (apart from the resevoir-pump combinations,) it pays to have a nice flexible extension fitted so the receptacle can be placed in a mangeable position.
It's amazing the change between an empty gallon can precariously balanced, and a full hot one at arms length!

I work in a lab so syringes are readily available and cheap. For oil I think I'll splash out and get something that makes the job easier, sometimes I try to be too cheap and it makes life harder than the saving is worth.

I'm going to try to pump the majority of the water out of the bilge with one of these:

though thinking about it the bilge pump should do it.

Due to the viscosity of the oil, even when warm, it's probably better to get a peristaltic pump.
There used to be some hand-driven versions available to transfer fuel for models.
It needs to go slow or the pipes implode, having softened with the heat.

a peristaltic pump.

I had to google it, then found that I should have already known it.



Wikipedia

No3 son has one to transfer RO water into his salt water aquarium.

Commercial dishwashers in hotel kitchens for example use them to add the wash and rinse chemicals into the machine.

Aquaplane didn't give a link to go with the photo of his drill driven pump, but chasing it back gives

DIYTools.

Seems a useful site, anyone have experience of using it?

With the brass pump which I linked to above, I find that when you pull the piston out on the suction stroke you need to hold it there for a while until the piston fills up. This is more obvious if the oil isn't warm enough, or if you've forgotten to take the filler cap off the top of the engine!!!

As it happens, I can get hold of a peristaltic pump easily too My main problem is power, not that it's a problem, I just don't have access to any.

I thought of an application in the lab and got one of those drill pumps to see if it would work, it does. It's not utilsed much so it's available for loan most weekends if anyone needs to see if it works on other jobs. I can't remember where it was sourced, I couldn't find it in the RS catalogue, or B&Q online when I was looking for a picture though.

Again I am sure Silverline tools do them.

My drill-driven impellor pump self-destructed PDQ. that's why I mentioned the old intestinal job, it goes slowly enough to cope with the viscous content.

I use a brass pump as pictured above - about £12. It works very well with hot oil, and don't try to do it too quickly.
