my diy deltec skimmer (lots of pics)

[spazz]

i did a test with the watt meter to see what it drew for power. they state that the pumps are 38watts each but mine only pulled 35 watts each for a total of 140 watts. thats a plesent suprise.
its nice that they are effecient and quiet to boot. plus cost less than a sedra.

Looks great! Could you put up some more info on the OR pumps -

What did you use as a venturi? Are the output of the pumps metric? I've heard great things about them and I'm excited that you ended up using them.

 

[JMAONE]

More than well done spazz! I'm also gonna build something like that but still looking around for parts... puh!

I love your skimmer! I'm a big fan of the OR 2700s since I used one to replace the Sedra 5000 on my CS 6-2+. Do you have details on the air intake for the OR 2700s?

ejasmrhere, you can get the OR 2700s for $49.95 from Custom Aquatic.

Nice. I will have to look into picking one of those up soon. Now we'll have to keep bugging spazz to give us more info on the plumbing and the venturi

give me a few hours and i will give you all the info on how i built the venturi. im in the middle of gluing a 4"x4"x1" clam tank for a friend. and cant be away long. its so cheap and simple it will shock you.
just a hint to give you something to reasearch, marinedepot in the john gust fitting section is where i got the fitting and did some intence mods to it. i will post pics of the mods and tools to make it.

sorry guys i started to look for that fitting at marine depot and i realized i got it at priemum aquatics. here is the exact fitting. if you sand off the washer in the middle so its just a tube with a barbed end then sand the end at a 45 deg angle. and to add just a little more air drill very small holed down the end of it .

i drilled the 1/4" hole on the metric fitting that is threaded to the pump housing.
i will make a fitting and post a pic tomorrow. im so busy with this tank right now.

As you mount OR pumps on a skimmer.. Do you have any problems if air stay in pump when the pump is switched off.
Is there any possibility to stay enough air in the pump and then when you start pump it pinwheel spin around in air and therefore pump can not suck any water?

You are using OR2700 pumps form Aqua Medic with internal pin wheel impeller?

 

[merlock116]

make sure you support the airline tubes up towards the top of the skimmer or the water will spill out if you ever turn the recirculating pumps off but I'm sure you already know that.

yep this was just a wet test in the driveway. wanted to test for leaks in the plumming.

i turned them on and off a couple of times and all the pumps restarted with no problem. there was a little air in the pumps but it wasent enough to cavate them completely.

I only had that problem when I put a 90 on the outlet, inside the skimmer in hopes of directing the foam down to gain more contact time. It trapped air between the pump and 90. This could be solved by drilling a small hole in it to vent the air.

 

[ejamsrhere]

yo spazz... a bit more detail on the venturi please

 

[spazz]

sorry i forgot. i have built 2 different tank (1 4'x4'x2' and 1 4'x4'x1') in the last 48 hrs. i have been in the shop 18 hrs a day. i will try and get the pics and a full discription of them tomorrow.

 

[ejamsrhere]

Nice. Thanks spazz. I envy you. I wish I could spend days at a time in a workshop.

sorry i have been so busy lately. here is the pics of the venturie i made for my skimmer. also here is a pic of the keyed flanges igot from the cnc guy. it only took him 2 months to make them. then he didnt cut the oring grove deep enough. so i had to recut them deeper. but after the refitting of the flange its almost ready for the tank.


this is the ventirie i built for my pumps. i bought the fittings (on right) and drilled super small holes down it. then angle cut the end. the washer was sanded off also.

here it is almost ready for the tank. i cant wait to see the skimming power of this baby.

 

[Lunchbucket]

wow buddy that is really looking nice.

hmm interesting venturi's. hope they work good

[ejamsrhere]

So did you just drill a hole for that and let the size of the JG fitting make a reuction in pipe size? Ineresting way of getting it done. Can you measure air intake when you get the beast working? Looks great!

 

[spazz]

i tested it a little and im getting too much air right now. the bubbles fill the body right to the bottom of the skimmer. i have to make the inflow and out flow yet but i have to also figure out a way to restrict the in flowing water to the pumps. the venturies take a 1/4" hole on the main pipe. there is no specal way to mount them. think of a carburator on a car. the venturie is made the same way.

well i finaly got my skimmer up and running yesterday. so far so good. it didnt start to produce smimmate untill the next day but its making up for it.
