Starting to build my wmo collection/filtration setup .

[homelessduck]

I am now realizing a big mistake that I made. My 2" pump is too large to collect oil from most tanks and any drum without the top removed. Oops...

Do you guys think I could reduce the end of the hose to a 1 1/2" or whatever is needed to fit through a 2" hole, or would it cause problems with the pump? I think I read in the owners manual that you should NOT reduce it any ..

All this time I thought I had a 60ish per gallon/hour 'fuge but after looking at Pabiodiesel's site to confirm, it looks like I have the 108 gph. Did they change up recently and stop carrying a fuge that was between the 55 and 108? Anyway, it's definitely bigger than the 55gph model....

What size is your centrifuge? Mine is only a 55gph , maybe the size makes a difference in whether or not you hear it lift?

I think you'd be fine by reducing it to 1.5", I can't see how a 4' long 1.5" wand on the end of a 2" hose would break the pump....if anything it seems like it would make it suck harder. That said, aren't most bung holes 2"?

2" pipe thread, but i'm not sure the actual diameter of the opening...

 

[homelessduck]

Yep, 2" pipe thread so a 2" PVC suction stick wouldn't fit. I'm not sure about the fuge sizes, I am pretty sure they offered one slightly larger than mine. I remember thinking I should have spent the extra $10-20 for the larger one.

 

[Kalashnikov]

I reduced my 2" pump to 1" hose and it will fit in a 55 gallon drum hole with a 1/2"ish OD depth stick attached. Probably a few thousand gallons on it with no issues.

 

[leswhitt]

I just checked my previous order and sure enough, I have a 108 gph 'fuge. For the last few months I've been calculating my cleaning at 65gpm so I've been cleaning at roughly double the passes that I thought! It's nice when you make a mistake in your favor every once in awhile

My sucker is 1.5" and has no problems fitting in bung holes or the smaller lids on top of totes....I used it just today as a matter of fact. I don't know that I'd reduce from 2" all the way down to 1", it seems like your speed will suffer quite a bit.

Kalishnikov; Do you see a big speed difference from 2" down to 1"? Does the pump sound like it's having a really hard time or does it chug along as usual?

And thanks for correcting me on the 2", I don't know why I was thinking a 2" pipe would slip into a 2" hole...old age I guess and probably the same brain malfunction that had me thinking my 'fuge was 65gph when it's really 108gph. Duh!

 

[homelessduck]

I reduced it down to 1 1/2" . It fits now. Hopefully it won't cause any issues but if it does, I have a warranty on the pump .

The one thing that I see being annoying is that my suction hose is EXTREMELY stiff. It is very heavy duty which makes it rock hard. Should be fun trying to maneuver it around.


Edit: I only reduced the end of the hose where the PVC is connected. It is still a 2" hose.

 

[leswhitt]

I feel for ya on the stiff hose, mine is moderately stiff partly because of the diameter and weight but it's still a pain trying to position it when I only want to suck from the high corner of a tote. The wand is great though, it makes it so I can store the hoses inside my truck (I have quick connects and just connect the hose ends) so they'll be warm and a little more flexible and leave the wand outside.

The only part I have left to do is put a strainer on my wand so I can protect my pump impeller. Strainers are expensive though so I think I might just use flexible window screen and a band clamp instead.

 

[homelessduck]

I was thinking the same thing for the strainer . I have a quick disconnect at the pump but not at the wand. I didn't think ahead and I'm just going to deal with it. I also only have a foot valve at the pump on the suction side. I will add a valve on the wand later.

 

[homelessduck]

Also, I capped the end of my wand and I'm going to drill a hole 1-2" up so that I can just toss it in the drum and not worry about sucking the junk on the bottom.

 

[leswhitt]

FWIW, I had a foot valve too and never even put it on. After about 20 secs, my pump starts sucking fluid and away she goes. If I think the oil is thick or the weather is cold, I'll put 3 or 4 qts in my suction hose and then it'll start right up. I know a foot valve is only about $7 but with these pumps, you can save that money

 

[homelessduck]

The cheapest foot valve I could fine was $15 , but everything is over priced around here. The hose clamps alone were $2.50 each. I couldn't believe it. I mainly wanted one so that oil wouldn't drain out and make a mess when I took the hose off. We'll see if it actually prevents that

I went straight to 1" suction and 3/4" output hose. In the colder temps you can hear the pump load up some with straight WMO but it still flow plenty fast. Thinned out it's a lot less but it alway keeps chugging.

Are these foot valves the same thing as a check valve or anti drain back valve?

What kind of quick disconnects are you using? I'd like to set mine up with some but the ones I was looking at leave the hose open after you disconnect which would be a pain to drain all the oil out everytime.

 

[homelessduck]

I just have a camlock fitting. The foot valve is the same as a check valve. I got in the habit of calling it a foot valve because no one knew what I was asking for until I called it a foot valve haha.
