you pull now 50LPM= 3060LPH it's great result and i don't believe you will get it with the metala , you can make other test try to cut from the matala half size from the thickness to see how this material perform compare to the PF4. |

at least 15-20% more than I can measure. When I put the air meter on the pump it raises the wattage by about 15 watts. More air equals less wattage. It has the 3/4 in hose pretty loud sucking air. When restricted with the meter, the Dwyer literally whistles and the water level drops a bit. Mike |

i need to check the size of the pump compare to the RD 6500 liter , i want to know if the pump high the same i thinking to order now the ATB big skimmer i am waiting for some answer.....
but this is the skimmer ( 30" high - 17" base): ![]() |

When are you getting it? I think this pump will fit it. It looks like a 1 inch inlet on the bubble diffuser pan.

Hah... whaddya know... the idea worked. Lol. Better than expected too. I mean, sure, well have to see how these things wear over time, but even if the shafts break every year or something... its still a deal.
I dont know that a custom volute would be of any improvement, as the asymetric design and contoured interior of the Laguna is a good design as is, and if smjtkj will do me a favor of measuring the interior diameter of the volute... that may be all we need.

Ime, one different between stock volute and large diy volute is the noise. With stock volute, when the pump is used externally you can hear the noise within it, while large volute is almost silent.

If its due to size rather than material thickness, then the 2400/2905 versions with the larger volutes might not have the noise problem either.

It is under water right now, but the 2400 is silent. Now the air intake hose is something different! Maybe it is the larger volute
that helps. Quangtam, I know you have shown pics, but I would like a list of materials used for the volute you made. Thanks in advance! Mike |

Not sure where you are buying the Max-Flo 2400's but I found that they are on sale at Foster & Smith.
Also wanted to ask if anyone has see these pumps, I found them on the same site and they look to have a nice large volute. They are the HY-Drive Waterfall Pumps. The smallest one is rated for 3,250 gph @ 150w. ![]() |

Yes, I saw those, but the wattage is a little better on the Lagunas.
The volute is nice and large though. |

Yeah the wattage is not as good and the pump is larger too.
Where did you get your 2400 |

Look at the second pic. Just a 3/4 barb cut at an angle.

Does anyone have a max-flo 900? The 2400 is nice, but I don't thnk my modified NW-200 has any hope of handling 100 scfh! I am interested in modding a 900 with hopes of getting 60 scfh @ <40 watts. Is the volute large like it is on the 2400?
Anyone have pictures of a max-flo 900 so we can assess it's potential for being a smaller DIY red dragon? |

Hey guys, I havent done it yet, but I think if you take a 3 inch PVC coupler and cut it down so that the ring of pvc in the center is where the O- ring is around the base of the laguna pump, it will be snugg, at least on a 5000, and is an easy PVC shroud that can be used for preliminary tests without having to go CNC yet. Will post pics when I get mine done

kroe,
I dont thing that the Max flow has a floating impeller, ie it has a shaft that goes all the way through so it will be harder to make a customized impeller shroud |

Cool dudedudedude! I will be watching.

hmm i should mod my 5000 tonight. So we just use a dremel and slowly cut away from the center until the brass tension ring is off. Do we keep the original plate or do we replace it with a disk the same size?
