Darren, hehe your telling me.. althought it is a little different for a car.. all the losses in a care are after the motor that is rated.. and it is not hidden that it is flywheel horse power.

I agree that the Dolphin looks like a cool pump also.

JFYI, hot tub pumps are never rated at 0 head so infact there out put in all realaty will probably blow the dolphin away.. here is a example of my pump on my hot tub to show you what I mean. mine is a little more powerfull than a dolphin but it shows you how they are rated.

HP 1.5
Volts 120/240
gpm@30 ft.(head) 127
gpm@40 ft.(head) 105
gpm@50 ft.(head) 50

so that is over 7600gph @ 30 feet of head ( I want to see Titus put that baby on his tank :D :D ), and it cost me 180.00 for motor and pump. it does use a lot of power though.. 8.2 amps on high speed and 2.2 amps on low speed using 220 power (this is MAX DRAW ratings.. now wattage rating whatsoever) and is a little more noise.. not to bad though.. a insulated cabnet would quiet it right up.. the best thing is thease pumps are designed to run 24/7 for 10 years. in the situation of a sump in the basement I think this would be the way to go on a big tank.

the dolphin pumps look very simuler to a hot tub pump motor but what I suspect is that it is a smaller power motor with a smaller pump end..and you are paying for the quietness of the unit. hell it is still better than any other pump in the fish industry from what i have seen though [img]smile.gif[/img] another thing I noticed is they the aquarium industry is infatuated with wattage to the point of what we have seen here.. using almost useless #'s for the sake of compatition.

I almost wonder if I could buy the same thing for 1/2 the price at my local hot tub dealer... hmmm are there any #'s stamped in to the plastic pump end on your dolphin? would most likely be on the outside of the impeller housing.. I get good deals at the local hot tub place maby I could order the pump ends in.. then it is just a matter of getting a good pump to hook it to [img]smile.gif[/img]

Oh I am going to see if they have any pumps there that are 1/2 HP or less so I can see if they would work also [img]smile.gif[/img]
