Got my pump.

Cieprus · 05-23-2002, 09:49 PM

Its a flotek 350 GPH 120v, Anyone heard of it.

Petsmart didnt have any Danner

Cyco-Dude · 05-23-2002, 10:31 PM

well, is it mag-drive or does it have a seal? if it has a seal, it could be a problem down the line. but that pump seems very powerful (60GPH @ 40 feet!?? damn!). i wonder what its GPH is at 0 or 1 foot?

Its GPH at 0-1 is 350.

How can I find out if its mag drive, or seal ??

From the diagram, it looks like the motor is housed alone, and the inlet-outlet is housed toward the end, the motor will virtually contribute no heat to the water, because the water will come nowhere near it.

Cyco-Dude · 05-23-2002, 10:37 PM

look for a spec speet or a parts list. you could take the housing off and see if its got a magnetic shaft / impeller assembly. im thinking its not a mag-drive tho from the description "brush style motor".

about how much space does this thing take up?

Well its about the size of the Eniem. It has a metal bracket to keep it flat, which could be taken off.

Its pretty small, small enough to fit in my case.

Yes the pump does have an impeller.

Cieprus · 05-24-2002, 08:26 AM

My pump is sooo loud!!!

It is soo soo soooooo loud! WHat should I do????

bigben2k · 05-24-2002, 11:57 AM

Return it.

You didn't get a mag drive, you got a direct drive... It's the most powerfull you can get, save a piston, but it is (as you found out) the loudest.

Cyco-Dude · 05-24-2002, 12:27 PM

not to mention the brushed and seals will eventually wear out and need to be replaced.
are there any Petsmart stores near you? they would probably have the 250GPH danner.....

So its powerful?

But what do you mean by save a piston?

I can build something to contain the noise.

Cyco-Dude · 05-24-2002, 12:31 PM

he means a piston-powered pump.
and by looking at that flow chart, id say that pump is powerful.

Powerful how?

It is VERY heavey for its size, its heavier then the 950 GPH that I returned, and a little less than half the size.

ambient · 05-24-2002, 01:14 PM

you would probably have to grease that pump too. Where the mag drive needs no grease.

bigben2k · 05-24-2002, 01:40 PM

Yes, I meant a piston-powered pump. It's like an engine block, but instead of air-gas, uses water. It is usually gas driven. It's also not usually meant for 100% duty cycle, and requires regular maintenance.

Cieprus, I know you want the best, but you're gonna have to trust us on this, the direct drive or piston-driven is not the best choice. Power is good, but not that much power!!!

What you need is to shop for a pump that:
(pick and choose yourself here)
1-is quiet
2-has a decent flow rate
3-can run continously (i.e. 100% duty cycle) (i.e. is reliable)
4-Requires no (or little) maintenance.
5-Has fittings for your tubing size (or can easily be adapted)
6-Consumes very little power (around 10 to 20Watts is good)
7-Cost little
8-Has been used (therefore proven) for the application that you intend for it (this covers all the other bases I may not have mentionned)

There. What you do from now on is up to you. If you want to use the one you have now, that's just fine. If you want tips on how to isolate it for noise, here's a few:

(but first, keep in mind that if you have to perform maintenance, you'll have to have easy access, and that if your pump requires ventilation, it'll have to be built in. Also, you'll have to route the electric cord)

Basics: to isolate noise...
if you're trying to isolate a high pitched noise (i.e. a beep), then solid objects do that best.
If you're trying to isolate a low frequency noise (i.e. a low rumble), then soft materials do that best.

I can't hear your pump from here, so I'll just give you a few ideas.

a) a wooden box.
b) a steel box
c) a heavy cardboard box
d) a plastic box

You can then add padding, inside or out. You can build a latched cover, if you need access for maintenance. You can cut long slim vents, if it needs ventilation, etc...

bigben2k · 05-24-2002, 01:51 PM

One more thing...

Boxes have this nasty tendency to turn into resonating boxes, at a specific frequency range. This would actually make your assembly/setup LOUDER. There's ways of calculating that, if you're interested. It's often easier to avoid that effect by leaving one of the 6 sides open, or by cutting some openings.

Cieprus · 05-24-2002, 02:33 PM

Everything you tell me is taken into consideration, but are you sure its a piston powered pump?

That is really odd, I mean, its a motor, so...Piston powered?

The maintenance is really simple, 2 screws to grease it up nicly.

Someday Ill save up some money and get an Ehiem.

Ya, I went to Petsmart, and Petco, they didnt carry ANY Danner pumps.

They didnt have anything good either.

Cieprus · 05-24-2002, 02:59 PM

One more thing.

It saids right on the pump.

Motor operated pump.

&

Thermally protected (Which is great.)

bigben2k · 05-24-2002, 03:31 PM

"Thermally protected" means that if the pump overheats, it will automatically shut down. (You're going to run MBM, right?)

I don't believe that your pump is piston driven, I just meant it as an example. Your pump is direct driven, meaning that the motor shaft drives the impeller directly. Your impeller is probably sealed in some type of housing attached to the end of the electric motor. If you look closely, you can probably see the motor shaft.

A mag driven pump doesn't have a motor shaft, it moves a shaft by magnetic induction. (the advantage of which is electric isolation from the fluid). The shaft is completely encased in its own housing, which is surrounded by electric coils.

The site had the one you have, which I want, but I need it fast.

Ya i know about the thermal protection

Ya I just thought you thought it was piston driven. And I didnt know why.

i guess Ill have to deal with it. Till I can get a Ehiem, or Danner.

But its a good pump, should last awhile, and after I get a better one, I can use this one to drain the pool

bigben2k · 05-25-2002, 09:07 AM

Ok, Cieprus, I'm glad we cleared that up!

I have another tip for you:
Make sure that you clamp all your hoses very tightly.

Here's why: Many people use an aquarium type pump (like an Eheim or Rio) and these match the requirements that I listed earlier. What I didn't mention is that the drawback to those pumps is that they are not very efficient. (That's why Cyco-Dude is impressed with your choice). If you got an Eheim 1250, rated at 317 gph, you'd also notice in the specs that the 1250 CANNOT flow water 40 feet up.

Using an Eheim 1250, the actual flow rate would be more along the lines of 100 gph (because of its low efficiency).

The pump you have will be more efficient, and I suspect that you may be able to achieve an actual flow rate somewhere between 150 and 200 gph. That's good if you want a high flow rate, but bad because it'll put a lot of pressure in your system such that a leak may spring much easier.

(this is one of those good-bad things. Your choice of pump is still very commendable)

You might have another advantage in that your pump may not put a lot of heat in the water, but I can't say for sure.

Overall, I think you're on the right track. I just hope you can put up with the noise, or find a good workaround.

ECUPirate · 05-25-2002, 11:32 AM

errr... you should still get a mag drive pump... something you can "fire & forget". "Regular maintenance" means taking the pump apart regularly to check seals and to lube it up, and that involves either draining the system, or something similar.
Ben's right about the flow rate of the 1250... it does NOT put out anywhere near 317GPH when installed in the system. But it does work quite well.

Ya. Well I plan on getting a better pump, Like Ehiem or the Danner.

But for now it will do.

Ill have to make a box for it, to keep the noise down.

Oh ya, Im using all metal screw clamps. Ugly but very strong.

Thanks guys

Cieprus · 05-25-2002, 01:53 PM

Well this is going to be hard to describe but ill go for it.

The pump im using has a housing just of the impeller, there is a metal plate that seals this all up, and I can take hte plate off to oil the impeller, unclog things, and anything else.

So it will DEF not add heat to the water, the motor is about 2-3in away from the impeller inlet/outlet housing.

But what If I put a NICE heatsink/fan on that metal plate?

Think it would help at all? Maybe if my pump was pumping the hot water?

It would look cool as hell
