new pump for the sump..

[meshman10]

so, I'm setting up my first sump system and was wandering if you guy's and gal's had any any thought's on a sump pump.. now for the spec's
90 gal main
30 gal sump
6' to 6.5' of head (+/-)some 90's. this is where I'm at so far:helm2:
Iwaki MD Water Pump (Japanese Motor)

Is the tank reef ready or using an overflow

 

[meshman10]

overflow..

 

[Reefrookie]

Based on the motor you linked to after your head loss( I used 3ft vertical,3 ft horizontal, and 2 elbows) I think you wind up with about 415 gph.. You can use a hang on overflow rated up to 600 gph like this on CPR CS Overflow Boxes or you can use a return pump that is run from in the sump and not external ......Hope this helped!

the main tank is drilled with a built in overflow .so after talking with an IWAKI rep I now realize that, that pump will not work it's made for flow only (no head pressure) so I think I'm going with this model instead.

Iwaki MD-30RLT Pump . if my calculation's are correct I should get around 7-8 GPM and that = 420 - 480 GPH.any thought's??

go to bulkreefsupply.com and check out their panworld pumps they are the exact same pump but the panworld pumps are cheaper

wow those look nice and half the price of the Iwaki I will have to remember that for my next build.

the same person that designed most of the iwaki pumps designed the panworld pumps also

Does anyone know how much heat a panworld external pump may add to the water: I am upgrading my tank to a setup very similar to meshman10 (20 gallon sump with another 20 gallon refug with the 90 gal tank) so the panworld pumps look good but I house seahorses where I need to keep the temp at 74 or under so not having to run my chiller as often saves me tons of money. Trying to find a good external pump that will not add much heat.

Thanks

my father-in-law has a blueline(same as the panworld) and it does not add any heat to the tank.
