SEAFLO 12V Self Priming Impeller Gear Pump - 3.2 GPM Oil Change Diesel Fuel Transfer Pump, Reversible Flow, Copper Impeller, Rugged Metal Gears, Self Priming Design, 4 Year Warranty

This SEAFLO 12v Self-Priming Impeller Gear Pump has been an absolute lifesaver for my Chrysler 300 supercharger oil scavenging project! Finding a reliable and compact pump for this specific application can be tricky, but this SEAFLO unit has performed flawlessly. The self-priming feature is fantastic. It makes the initial setup and operation so much easier, as I don't have to worry about manually priming the pump. Once connected, it quickly and efficiently draws the oil out of the supercharger. The 3.2 GPM flow rate is more than adequate for this task, making oil changes and maintenance a breeze. The build quality of the pump feels robust and durable, exactly what you need for handling lubricants. The 12v power draw is manageable and integrates easily into the car's electrical system. I was particularly impressed with how consistently it operates, providing a steady and reliable flow every time I've used it. For anyone with a supercharged vehicle, especially Chrysler 300 owners tackling oil scavenging, this SEAFLO pump is a game-changer. It simplifies the process, is built to last, and performs exactly as advertised. It's a well-engineered piece of equipment that has made maintaining my supercharger significantly easier. Highly recommended!

Works great, I read the negative reviews of leaks on threads. Easy fix with the British threads add metric o-ring to the fitting and all is well. Pumps well with no leaks. I bought nitrile o-ring kit from Harbor Freight because the large assortment kit is cheap.

I use this pump to drain and refill oil on generators. I don't use it on a daily basis, but when I've had the need for it, it's definitely helped out in those situations. Almost takes longer to set up and get going than it does to drain out the oil. It can fill up/drain a 5 gallon bucket in about 90 seconds (just an estimation, I haven't timed it). The pump comes pretty bare bones though, only the barb fittings and two short cables for connecting to a battery, you have to put in the work to make it more convenient to use like extending the battery cables and adding an on/off switch if you wanted. If you want to change out the barb fittings that come with the pump to something else, good luck trying to use the info on the box because it's wrong. Like other reviewers have mentioned, the threads on the pump are not 3/8" NPT (National Pipe Thread), but actually 3/8" BSPP (British Standard Pipe Parallel). I added some quick disconnects, but first I had to take one of the barb fittings to a local hydraulic shop so they could tell me what the actual thread type was. If you use a 3/8" male NPT fitting, it will thread into the housing, but you won't get a good seal and it will probably leak. So overall, a pretty decent pump for what you pay, but I wish they would correct the info on the packaging so people can avoid wasting money buying fittings that aren't the right thread type.

Use pump to perform oil changes in small to large Generators. The gear pump design is holding up better than the rubber impeller models. Used in diesel fuel, waste oil, clean oil (15W40) and antifreeze. So far I am impressed.

The pump worked okay initially but quit after only a few uses and just outside of the window to return it. I would not recommend this pump

Just what I needed

Used this for oil changes in a boat make sure to prime for first pull and inlet side use reinforced automotive rubber hose do not use tugging inless heavy wall will collapse about 2 to 3 min to clear a 10 qt oil pan

I used it less than a dozen times and it went out. Only used it for hydraulic fluid, it did not like it.

Anfangs war ich doch zufrieden, jetzt nach dem vielleicht 4. mal Öl umpumpen aus dem Auffangbehälter in das Sammelfass hat sie ihren Dienst quittiert! Lief kurz an, dann ein Brummen, Rauchwolke und Ende, schade fast 100€ in die Tonne

I'm using this on a waste oil system and it pumps so much I had to buy a controller to ramp down the flow. (and that's after I used a tee to direct half the oil back into the reservoir..)

Fonctionne très bien pour l'instant

Bought it went to install it and rust in the impeller and no orings for the fittings

This the first pump that worked with heavy diesel lub oil. Should have bought it 20 years ago and saved myself a lot of misery
