Closed Loop Pump Sugestions

[RoGeTa]

I needed some quick suggestions on a pump for a closed loop system. I would like a fairly quiet pump that does Approximately 1000 gallons per hour. There will be 5-6 ft of head pressure as well.

that head loss will almost be negated by the pressure of the drain water pushing down on the pump. one of the beauties of closed loop :)

for external pumps, i recommend the Pan World pumps - they are very quiet and they look awesome. I have the 50PX-X and it is rated at like 1100 gph.

For quiet, the Poseiden (previously called Velocity) pumps are silent. They do add some heat into a system (1-2 degrees F. ...at least that's what they say)... although, I've never had a problem with heat. My system is 78-80^F right now. I guess it depends on what you set your house AC temp. I do have a small fan on the each of the pumps in case that does help cool it down. I don't know if that works or not... or what my tank temp would be if I turned off the fans. Sounds like an experiment. :D

My closed loop T4 has been running for 5 years and my sump pump T3 for 4 years.

You cannot hear them running.

Awesome! I was hoping for some feedback on these two pumps, they were high on my list :D

ha. cool.

I did have a Quiet One sump pump that I bought in 02'. And it worked fine till 12 months later.... it split in half. Yes, the outer casing cracked in half. Luckily, the saltwater didn't escape or I would of had a flood. So, I replaced it with the Velocity T3 pump.

But, keep in mind... this Quiet One was an 02' model. I have no experience with the new ones.

yeah if you are going to buy a pump that is critical to the system, you shouldn't be afraid to spend some money on it. spending a little more is an investment that will pay off overtime.

those are awesome pricey and worth it pumps.

the only problem is they go from 800 to 1200 gph, and the original poster was looking for 1000gph. probably not a big deal, though.

I really don't consider the Poseidon pumps to be expensive. The Iwaki pumps I consider to be expensive.

Also, the 1200gph is at 4 ft of head and rogeta has 5-6 ft of head.

I don't have any experience with any other pumps, but it is an ease to clean my Velocity pumps. I use Muriatic acid (20 % solution of HCL). You can buy it at most Swimming pool products business. It is, even at 20%, a very strong acid, much stronger than vinegar. It is very important that one use extreme caution when using this acid – it will burn holes in clothing and severely burn human skin.

The calcium deposits are gone in seconds and left with a smooth surface.
