feedback on pumps

[luckyarbuc]

Anyone have experience with a Velocity T4 or T? pump? I read they ran very hot which is a concern. The compact size and a flow rate between 1100 and 1300 is good for my application but I would like to make an informed buying decision. Any thoughts on other pumps?

Velocity pumps do run warm. You may want to look into Gen-X PCX-40 pumps, or Blueline 40 (I believe that is the correct model). Both are very quiet and workhorses.

is this for a sump return or a closed loop?

i use the t4 for my return and on a 210g i didnt notice any added heat issues. and the pump is dead silent.

I will be using the pump for amclosed loop system.

 

[joeycadre]

get a sequence for closed loop. dart. i have one on my 90 and i love it.

 

[luckyarbuc]

I looked at the Sequence pumps but the flow rate is too high. My return is coming into a 1" Sea Swirl with a maximum flow rate of 1150 GPH.

I am watching a Gen-X PCX-40 and an Iwake MD-55RLT on e-bay right now.

If someone has one they want to sell let me know.

Depending on how your closed loop is arranged and based on your output desires , I'd choose the PCX40. I've got a couple that have been running since 1995. They are almost bullet proof.

With the exception of the Tarpon and 55RXLT I have used or still use all the pumps listed above.

Thanks Dave, this is great information. I am building a 1" DIY intake that will flow through the pump as well as a chiller and return to the tank through a 1" Sea Swirl; any reason to have a pressure rated pump for this application? I don't think so, but I thought I would ask.

 

[just dave]

Because you are running it through a chiller and a Sea Swirl I would want a pressure rated pump. The pumps output would need to be tailored to the chillers flow rating ( including all the restrictions it will encounter) and you can use the calculator found on RC to best determine the pump size you will need based on your layout.

i have a dart running through a 1" seaswirl. i also have 3 3/4" outlets. it works fine.

I am at work. I'm putting together orders.

You can cut it up and use it in the reactor or you can roll it around the center tube.

 

[joeycadre]

roll it around? hmmmm. i never would have thought of that. so it doesn't matter if i have the white side in a certain direction?

dave, the man with the answers.

i've been hitting you up for info since 1994. you know i sold chris his first reef tank way back when?? i had forgotten until he told me a couple months back. and i bought that tank from you.
