Fluid Transfer Pump

[MolaKule]

Here is Mola's Almost Dripless Fluid Transfer System.

Here is a simple diaphram pump setup that I use, and it is good to about SAE 140 oils, warmed-up of course.

Materials List:

Item 1: Superflo diaphram pump - 12 Volts, SLV10 series, with On-Off switch on rear of pump case.

Item 2: 10 feet 3/8" ID vinyl tubing (the clear flexible stuff)
Item 3: 28" of polytethylene tubing 1/4" ID (Stiff, cloudy looking stuff).
Item 4: 2 - 3" Battery Clamps and 3 feet of 18 guage stranded wire, Red and Black.
Item 5: 2 - 3/8" hose clamps.

Tighten small Philip's screw on pump to prevent any leakage. found quite a few of these pumps came from factory with loose screws.

Solder wire to Battery clamps, and use inline connectors (or solder) Red pump wire to Red battery clamp wire and Black battery clamp wire to black pump wire.

Cut 3/8" vinyl tubing (Item 2) in half, so that you have 2 - 5 foot sections.
Slip Item 3 (polyethylene tubing) into the end of one of the vinyl tubing section's, up about 6-8."

Place Other end of Item 2 onto 3/8" barbs of pump's inlet and outlet, securing the hose connection with Item 5. The hose with the smaller poly tubing is the inlet hose, and the other of course is the outlet hose. You must have hose clamps at the barbs to prevent air from being sucked into inlet, and to keep hose from coming off outlet end when under pressure.

For removing fluids:

Put outlet end of vinyl hose into empty container. Put poly hose (inlet) into dipstick. If poly tube is too stiff to curve around dipstick bends, shove it down into diptick until it warms up, then push down some more.

Connect battery clamps to battery and turn on switch. I transferred one gallon of hot ATF fluid from a GM 4L60E in about 1.5 minutes.

For inserting fluid via dipstick:
Place inlet hose into clean fluid, outlet into dump bottle or tank to rinse system. A pint of clean fluid is usually sufficient.

Place outlet hose into dipstick and turn on switch. For automatic transmissions, make sure air is leaking past outlet hose so fluid flows into tranny and not out of top of the dipstick.

Hi MoleKule,

Thanks for the great device. A couple of questions:
Where can we buy this pump? Is it available for sale online? How much does it cost?

I should be extremely useful, especially for people like me with 4T40E transmission which doesn't have a dipstick.

Thank you,

I purchased mine at a Farm/Ranch store, but you should be able to find one at places like

3W.northerntool.com.

BTW, a correction on the pump name:

It is a Shurflo pump, not a Superflo pump.

You mentioned pump with a switch. But in your link the model SLV10-AA41 doesn't say it has an on/off switch. Model SLV10-AA40, however, has an integral on/off switch. So as I understand with model SLV10-AA41 you have to cut off the power supply, whereas with model SLV10-AA40 you just have to turn the switch off to shut the pump down. Otherwise both models are identical, is that correct?

Thanks,

The transfer unit that I made used an old filter housing that I found at the dump.

I drilled a hole and soldered in a standpipe that goes nearly all the way to the bottom, and drilled a hole and fitted a schraeder valve on the other side.

I fill it with whatever, put a hose on the standpipe, and into the diff, hook up a foot pump, and give it a few pumps, pressurising it.

The air pressure forces it out of the vessel, and into the diff. And the spitting gurgling sound that it makes tells you that the reservoir needs replenishing.

Titanium,

Good catch. The link should have been to the
Model SLV10-AA40 with the integral on/off switch.

I just verified that the one I am using is indeed the Model SLV10-AA40.

They will both work, but with the Model SLV10-AA40 you don't have to connect and disconnect the battery clamps to turn it on or off.

Thanks

The mityvac will only remove fluids, it can't pump it back in. My transmission fluid needs to be pumped in from below
