A Couple Stream Questions

First, I'd like the specs for the 6000's, spefically the wattages consumed by them -the variations between full power and low.

And secondly, I'd like to ask why the 6100 uses comparatively so much power as compared to the 6080. (Give or take some) the 6080 gives me 2250 gal/ hr consuming 17-watts of electricity while the 6100 will give me 3150 gal/ hr consuming 45-watts. That extra 900 gal/ hr takes almost 3 times the power to achieve, I was wondering why? The info I've seen about the 6000's (15 or 17-watts, depending on source, for 1850 gal/ hr) didn't seem to have such a big difference between power consumption of the "smaller" versions as did the "larger"ones.

Thanks.

And another thought, is there a reason why the "propeller" isn't larger filling more of the space inside the "cage" housing? Wouldn't a larger one move more water at nearly the same electrical load?

Motors operate on an inductive load- short of giving a full electrical engineering lesson, the propellor is the correct size a bigger one will irreperably damage the coil and ruin the pump, a european motor uses a bigger prop because it spins at 50Hz and the us 60Hz- 20% faster so 20% smaller. You cannot haphazardly modify pumps without trouble, a watt meter reading is required to verify you are not overdrawing the pump- the cause of RIO meltdown syndrome (hmm, could I say China Syndrome) The 6000 and 6100 are low voltage electronic pumps and the use of power is exponential. They use the same motor and the same electronics. The power is supplied in low voltage AC format, it is a completely different construction with a computer providing the HZ pattern. The pumps have a different size transformer to increase the power and trnasformers and computers use power to do their jobs. So you know, due to the higher resistance of 115V a US 6080 uses 21W. The electronic pump is unaffected by cycles or voltage and with the right transformer works the same the world over. I have no curve for energy consumption but it would be 8-45w for the 6100 and 6-15w for the 6000.

Thanks for the response. You know, actually the first thing I noticed about the pair of 6080's I got was all the open space surrounding the propeller. I was curious about it.

Again thanks.
