Has anybody used one of these pumps with WMO during collection or filtration? I'm thinking of getting one for starting my filtration setup.
Harbor Freight 1 inch clear water pump

I've run just about everything thru that pump with no problems. the only issue I really had was priming the pump. then everything was ok. I still have 2 of them if your interested. A friend of mine used one for several years as a WMO transfer pump with no issues.

are you using one for filtering. Mine is still in the box. I am wondering if I should set it up for pushing or pulling on the filter system (before or after the filters). My WAG says it should work fine in the before (push) mode.
I guess I am gonna give that hog a try on pick up. I did not think it would handle the goey stuff.

I use one on my WMO filtration system. It sits on the same platform the mix oil drum sits on so it is usually below the oil level (thus it starts out gravity fed / primed when I open the valve at the bottom of the drum). I push the W85 up a pipe to two 5 micron string wound filters then back into the top of the drum.
I am new to this so I have only had it running for a total of approx 60-90 minutes with no problems so far.
It flows just fine and if I want it a bit slower I just close the ball valve at the bottom of the drum a bit.
When done, I turn a diff. valve and it pushes throught the same two 5 mic filters then a 5 mic absolute filter into a gas can. It slows it down considerably going through all three filters (maybe 1-2 Gal/min w/ valve full open) but seems to work perfect.
It has been said "if you use a centrifical pump like the one shown, and you run into any water anywhere, the tips of the impeller can make homogonized oil/water milkshake crap which ruins the oil."
The single batch I have done showed no sign of water but I keep this in mind.

I have been using the HF 1" 110 clear water pump for 3 yrs. I was using it to filter my oil/rug/dino mix then pump to my truck. I was using a HF 12 volt pump for oil collection.
I now have a centrfuge for oil cleaning and picked up the 2" gas powered water pump from HF for oil collection. It works great. I can pick up 55 gallon drum in 5 mins.
I still use the 1" water pump to filter my mix thru a 10 micron fuel filter and a 5 micron water block before pumping into my truck. You can't beat HF for the prices and i use
20% off coupons found in the back of most mens mags.

I first had one set up as a push system for wvo thru 2 whole house filters. filters clogged very easily and was very messy. next set up was just as a transfer pump after a centrifuge and it worked great with every type of oil. my buddy ran his as a pull off a 300 gal wmo tank. worked good for about a yr then died.

Oil must be thinned to go thru and of those whole water filters They are made for water. Pumping thick oil don't work well. Same goes for the water pumps. They work better if the oil is thinned first. For $40 a pump if you get a year out of it thats fine. Get the replacment plan at HF and take it back before the plan ends. Get a new one.
I just tried my modified SBC pump tonight. All I can say is "WOW" this thing rocks. About 20 seconds to fill a 5 gallon pail with D2 running it with a $20.00 1/2" drill motor . I am really looking forward to picking up my first batch of WMO with it. I threaded the pick-up port with a 3/8 NPT and plugged the mounting port then drilled the pump body below the outlet and threaded it with a 3/8 NPT. I installed a 3/8 close nipple on the inlet and then a 3/8 - 1/2 reducer then a 4' nipple for the pickup wand. On the outlet I installed a 3/8 NPT to 1/2 barb with a 1/2 hose. My drill would not fit the drive shaft because of the factory drive slot so I had the boys at my machine shop to make an adapter from a piece of 1" round stock with set screws to secure to the pump drive and turned it down to fit my 1/2" drill. This is going to work real well for my oil pick up.

On the HF 1" 120v pump, are you having any issues with the flow being too fast for the filters during mixing? Since this will move oil near 10 gpm I wonder if that will push contaminates past a 10" whole house filter.

For best results I filter at about 50-75% of the filters rated flow rate and my filters are on the suction side of my pumps. There is no way a 10" cartridge will handle 10gpm unless it's coarse like 100-150 or more. I've got my process pump geared down with pulleys to run about 1.5 gpm and it works great. In a pinch a few weeks back I used my other pump, pulled through the stringwounds and pushed the absolute at about 3-4 gpm. I collapsed the absolute and got crud in both my tank and the neighbors. Cost us about 3-4 filters each. I will never put my final filter on the pressure side of a gear pump again! LOL

I was wondering about this too. Right now I push through the filters with this pump but I close the valve before the pump to slow the flow. It does slow the flow down quit a bit, but I haven't measured it. I'm still nervous about weather or not its pushing stuff past the filters. This is my first batch and I don't want to screw it up.
After rsr911's post I am going out right now to check the filters. At least make sure they are not collapsed.
rsr911, would putting this pump on the suction side of the filters slow it down better? 10gpm is its MAX rated with water. It's probably half that (at least) pulling/pushing W85 through filters. I guess I will pump to a bucket and time it.

With the filters on the suction side the most you can pull is one negative atmosphere (14.7psi) on the pressure side you can push what ever the pump can. I don't know how much pressure the HF pump can build but I know that gear pumps can easily go over 100. My guess is the HF pump can't build a lot of pressure so you may be fine. I like to do a bucket in about 2.5-3 minutes. Sure it takes longer but it works with the size filters I have. I recently got the 20" housing for my absolute and may go that way with the others as well but I'm producing 100-150 gallons a week right now. A big benefit to having the filters on the suction side is they will sort of self regulate, as they clog they slow the flow. On the pressure side of my pumps I can easily blow right past them without knowing it but on the suction side I can't.

I have seen this in the past while filtering some veggi fuel on a buddys set up. You can push sediment thru a whole house filter. Yes the 1" HF pump has the power to pump thru them.
whoah thanks for that word of caution. I think I will reverse my hoses.

It's up to but i only pull thru filters. Like rsr said then you know when the filters are get filled with dirt. I now use a centrfuge to clean my oil. But still use a 2 mic cimtek fuel filter and a 5 mic waterblock before pumping into my truck. Just to be safe.

Careful, most filters are not reversibile. Don't reverse the hoses, move the filters.
good comment rsr. I shoulda thought my comment out a little more and said something like move the plumbing around so the motor sucks the fuel through the filters instead of pushing it.
