best and most silent powerful pump.

jdthomas24 · 03/24/2010, 07:48 PM

Im looking for about 1000 gph once to the DT. I have a UV and chiller run inline with the pump and wiht the compact 5000 i bet i only get 400 or so to the tank. Head pressure is killing it. I seen some video on the red dragon pumps.. omg!! but they are to high for me. i need something virtually silent though.

sjm817 · 03/24/2010, 08:35 PM

There are other less expensive Askoll Laguna 1500 based pumps. The Red Dragons are not the only pumps based on this motor.

You can get the basic Laguna 1500 and MSX 1500 from Marine Solutions

All of those pumps mentioned aren't going to be good for any kind of head pressure. These pumps are absolutely silent and have decent head pressure ratings. People say they add alot of heat, but I have one of these as the return pump on my 120, its T-ed off running a phosban reactor and I have can keep my tank about 77-78 degrees without anything but a fan that blows over the top of the water and cools my T5 bulbs. The loudest part of my tank is the MP40w.

The poseidon pump above is very very quiet. I have one and you can barely tell its running. It raise my water temperature about 6 degrees though, I took it out of the system.

sjm817 · 03/24/2010, 09:05 PM

I also run a Poseidon PS4 pump. Dead silent. It looks the the OP was looking for a submersible. The PS4 is a 140W pump, the Askolls are ~ 75W. That is quiet a bit of difference in heat. Submersibles are not that great for high head use. You often have to compromise since it can be hard to get everything you want (quiet, high head, and low heat xfer).

thejuggernaut · 03/25/2010, 12:53 AM

Well what is your total system volume. You can do a little math to figure out how much heat the poseidon pump will add. First off its a 140 watt pump. Now lets say that the motor operates at 70% effeciency(its probably a little higher than that). But what that means is that only 98 watts of the 140 is actually converted into mechanical energy, the rest is released as noise and heat from both electrical resistance and friction. For the sake of this lets say that all of those 42 watts are converted to heat. And lets say that all 42 of those watts of heat are converted to the water, they aren't though, because much of the heat is released out of the metal case into the air, but to keep things simple lets say all the heat is released into the water.

In order to find out the amount of heat that is we need to convert it to BTUs. 1 watt is equal to 3.413 units of BTU energy, so that means that our 42 watts are actually converted into 143.346 BTUs. It takes 8.34 BTUs to raise 1 gallon of water 1 degree over one hour. Now lets just say you have a 100 gallon total water volume. In order to raise that 100 gallons of water 1 degree you would need 834 btu of heat, or 244.326 watts. So that pump would add less that 2 tenths of a degree of heat over a pump that somehow releases all of its motor heat into the air.

BlueStag · 03/25/2010, 01:03 AM

It's pretty well documented that the posieden pump puts out a little extra heat. It also is the quietest pump. A pretty good trade off. I run two of them on a 180 gallon tank. They do raise the temp of the water, more than other pumps I have used.

I also run a Askoll Maxflo 2000(one size bigger than the 1500). It handles 6' of head fine. I have to bleed a little because its to much flow for a 1.5" overflow. 1/2 the price of a red dragon, same motor. More flow than the 1500. Dead quite Why pay the extra price? I think the flow your looking for would be fine with the 1500

jdthomas24 · 03/25/2010, 07:37 PM

To all thank you for the input, i have been struggling with this for weeks and have been up in the air about it all. i wasted 180 bucks on a eheim compact that just doesn't do the job. I would like a drop in but if i have to go external then so be it. I looked into snapper reeflows today but just wanted to see the GPH versus sound levels.

The Poseiden Pumps seem to offer better range but more heat while the flow is good, i figure that with UV AND CHILLER I would need something like 200-2500 GPH to get 1000 GPH to the DT. What do you think? Right now i have 1400 GPH pump on their and i mayyyyyy get 500 out of it at the DT.

What? LOL... no i get it but everyone states that their temps would raise anywhere form 2-6 degrees.

mx270 · 03/25/2010, 08:02 PM

I just ordered a red dragon from marine depot. I have it ready to be connected up tomarrow. It was on clearance if that helps you. 2200gph @ 75w. I am removing a quiet one 9000. The 9000 is so loud I could no longer stand it. It also uses 140w.

jdthomas24 · 03/25/2010, 08:09 PM

i missed a RD 6.5 m3 on ebay- used for 250 the other day. I had to make measurement to see if i could submerge it in the pocket and when i was doing that it sold.. i would love to have one but they are to high for me right now.

on the flip side the Askroll pumps are based on the same motor per sjm817. I have looked at them also and they are a little expensive but not as much as the RD ones are. HMMMMMMMMMMMM DECISIONS DECISIONS

it doesnt seem that this pump has a higher GPH one. Its only rated for 480 Gallons at 16 feet. Im sure my calculations are not that great but i figured that i added at least 9 since i have a UV and chiller and about 8 feet of horizontal line and 8 feet of vertical with a T on it- 4 feet on both sides

mx270 · 03/25/2010, 08:24 PM

Good luck on your hunt. What uv light do you have that will handle that kind of flow?

Mounda · 03/25/2010, 08:35 PM

Yeah, that is definitely another variable to put in mind. In order for your UV to run effectively there must be enough contact time with the water, if it's too fast the it's useless. Why not get a dedicated pump for your chiller and UV ? Another Eheim ?

jdthomas24 · 03/25/2010, 08:52 PM

i have the aqua 40 watt unit. States it will handle up to 2900 GPH. So i would be good to go there. hopefully

jdthomas24 · 03/25/2010, 08:58 PM

I had the UV light inline with the overflow to the sump. Then the local fish store guy told me it needed to be on the return pump. I was only using one leg of the overflow for the sterilizer so this way i hit everything as it goes back to the tank. In theory a better way i guess. Thats when all of this started. the chiller hurt it bu both together killed my GPH

thejuggernaut · 03/26/2010, 12:36 AM

Well if you think you have close to 10 feet of head and still need 1000 gph flow your probably going to need a high pressure pump. Reeflo make the Tarpon which makes 1176 GPH at 9'. I hear they are a little louder than a Dart but shouldn't have much heat transfer from the motor. Honestly I think your going to have a hard time finding a pump that produces that much flow under that much pressure that doesnt create some amount of noise.

mx270 · 03/26/2010, 05:33 AM

It is a good idea to filter the water before running it through the uv light. I have 2 lifegard 40 watt units run seperate of my main pump. I run around 500 gal through them. I saw at Dr F&S that you only want around 300 gal through 40 watts to control parasites. I have mine pulling water from the skimmer compartment, dumping it in my refuge, and draining from the fuge via gravity back to the main pump compartment. This way the pods don't get a sun tan on their trip to the main tank!

pecan2phat · 03/26/2010, 12:22 PM

Sorry to butt in here but everyone seems very knowledgable on the subject.
I wanted to replace my Blue Line 40 HD due to the noise. It is extremely loud when used in a pressure enviroment. If I run the pump as a flow pump, it's not as bad but I am pumping up from a basement sump to a 1st floor display. Roughly about 12' vertical and maybe 8' horizontal.
I was also looking at the RD and Flowstar pumps but don't think that these pumps have enough head pressure so I was asking around about the Tunze 1073.90
Sounds good but Roger from Tunze stated that these pumps need to have regular maintenance in the impellar area so that kind of turned my interest.
Any suggestions?

jdthomas24 · 03/27/2010, 08:51 AM

Hmmm, I thought about the RIO 32Hyperflow pump but then i hear that some do not like their pumps. I wanted a drop in but if i need to go external then so be it, i will make some for it. So im on these pumps so far

Reeflo - Snapper
Dart
Red Dragon - to $$$$$$$
Poseidon

Askoll/ laguna pumps are only rated at 1500 GPH which may be a little low for my applications but who knows.

Av8bluewater · 03/27/2010, 09:14 AM

The dart is a great pump and very quite.. Just keep in mind that it takes up A LOT of room with the 2" in 1.5" out fittings. I didn't realize how much space it would take up.... especially if you install double union ball valves like I did. It's very energy efficient too.. 150W on my kill-0-watt. I had it running everything... Skimmer, return, reactors.

dolphin are not pressure rated, so the output will be drastically lowered.

I installed my Red Dragon pump this weekend. I can not hear it over my overflow. If I put my head up next to it, it sounds like a CD player spinning a disc. I am very impressed with the pump so far.

Have you considered running 2 quiet one 4000s. I have run these pumps and they are great for the money invested. They are rated over 1000 each at 50 watts. Maybe use one on your chiller and one on your UV?

tegee · 03/29/2010, 05:46 AM

Blueline recirculating pump have performed very well for me for years. Have three of them running in my livingroom (40hd-x) and are great, quiet and reliable pump from my experience.
