What pump did you end up with for this baby?

Thanks DD!
So I guess you could say for safety's sake that it could weigh in at around 3500# + if full of 300 gallons of oil and 22L of methanol...
I would say the feet and bolts would need to be good for 1000# each minimum? Maybe 1/2" plate with a 3/4" or 1" bolt would be better?

I scored 2 MP Series 110 pumps for $100 USD! Used of course from an industrial surplus outlet. They are 130GPM open impeller cast iron pedestal pumps, they are no mag drive but I am sure they will work fine for the price! I am prretty happy about that deal!
I will likely use one for my boiler feed just with a smaller motor since I have it. I wont really know what kind of flow I will need through the boiler until I get it built and start using it I guess...

-I answered via PM, not sure how to link it here for others to see Tom

Thanks Tom!
Here is what Tom PM'd me for others...

quote:

the way I would approach this is NO bolt type legs. You are looking at about 5000 lbs total loaded processor weight with 4 x 4 plates that would be exerting a force of about 78 lbs/squ inch on the floor. If you add 5/8 bolts for legs (which are not big enough), the weight transfer is more like 1250 lbs/sq in. (5/8 nut is about 1 squ in)
-I would for sure want that size of tank bolted to the concreate floor. Use a min of 5/8 anchors. use 3/8 steel for feet, and use shims to level. the shims should be the same size as the feet with corresponding holes.
-You are dealing with weight that can KILL instantly, please play safe Big Grin Tom
PS -If for some reson you must use leveling legs, use 1 1/4 bolts and secure the tank to the shed in a safe manner.

Cheers,
Jon

My processor has 1/4 inch plate pads with 5/8 bolts for levelers, no problems, it sits on a four inch thick concrete floor, there's no way a 5/8 bolt head is punching through a concrete floor, the bolts get screwed tight to the pads then turned out to level, on any given bolt there may be one or two threads outside the bolt.

fab Jon
-I've been in the manufacuring business for a loooong time! 5/8 as discribed be fab would work, but screw them out a half inch or so and you could be in trouble, bend a bolt and that tank is going down! I have a roller table by my cut off saw, it has 5/8 screw legs that are bent to chit, never had more than 1500 lbs on it. Tom

Edit info on the 5/8 bolt 11 threads per inch: diameter at the thead root = .507", area in square inches at the thread root .202, hmmm less than 1/4 square inch!! Tensile strenght =1,210 lbs. Source Machinery's Handbook

Thanks guy's!
I have the weight liberally figured in at 4000 lbs total full of 300 gallons of oil and 22 gallons of methanol, and that is still leaving 500 lbs for any errors I may have made, the actual calculated weight of 325 gallons of oil is (7.6lbs/gallon) 2470lbs + 1000 for the tank is around 3500lbs.
So if a 5/8" bolt is good for 1210 lbs, with 4 legs, they should support the weight fine providing they are kept short like mentioned and no lateral forces are applied... However they will be at their limit and I already have some hardened 1" nuts and bolts so I may just use them.
Whomever poured the floor in my shop was either drunk or blind, or both as there is not a level piece of floor to be found! I also intend to have the processor plumbed solid with black iron to the boiler so I will need a bit of adjustment to line it all up.
The processor will be in no danger of being knocked over as it will be in the back corner of my shop (until I can afford to build a pole barn ) and I am nowhere near an earthquake zone.

Jon

Just put three legs on the tank. Then you would only need adjusters on two legs.

YIKES!!!!!!!!!! I don't like that idea FF, three legs is scary unstable.

holy crap batman no way!! Tom

My FOUR-legged 44g reactor loaded with 150L of oil, on 39" legs, went through a 6.8 earthquake here in December 2007 and stayed upright. Ever been through a big earthquake? I'm with Robin, lol.

What are you trying to kill me FF?? LoL

Holy fudge! How did your home fair?
What are your processor legs made out of?
Good info!
Who's Robin?

Lots of other things in the shed fell over, including a load of steel shelving against a wall. Everything - contents - was a jumble. But standing in the middle of it all, upright and fully loaded, without any damage at all, was the reactor. Legs are 1-1/4" galv water pipe. They attach at the bottom cone at 39" from floor, and continue running up the drum to the lower reinforcing band, and are gussetted in between on each side onto the drum sides with 5mm steel bar. All tigged.

Full marks to Murphy, it's his design .

As for the house, it's timber and fared very well, but also the original front and back verandahs are now concrete and held the house in place.

A big earthquake is a very scary and violent thing. Everything around comes crashing down, the floor tilts and it's next to impossible to stand. Without warning.

WOW!
Thats quite a story!
Glad you and yours are OK...Including your batch of bio!
