water pump for electric motor?

about 2200 watts, depending what you pay for power it's close to $2000 per year to run 24-7

Hydro cost doesn't concern me, but by this concept I am looking at 40ish feet of head pressure. Like I said, I simply want to see what the pump heads cost, or even what they are called. From there I can continue my decision making.

You might want to try this calculator on reefcentral, I really doubt that you have anywhere close to "40ish feet of head pressure". http://reefcentral.com/index.php/head-loss-calculator

A horizontal foot of run counts for very little in the terms of loss and head pressure.

That's with the motor producing 3HP for that entire time, which it wouldn't be. I agree, it probably makes more sense to buy a purpose built water pump assembly with a smaller motor but aside from a few internal inneficiencies a motor will only pull the power necessary to run the load. When a motor is rated for 3hp that means it can safely sustain a workload of 3hp without overheating or being physically damaged, not necessarily how much power it will draw.

Actually the 2200 watts is being very conservative and assuming that it is not delivering peak power. Peak consumption of a 3 hp single phase motor would be closer to 4080 volt-amps, or a draw of close to 17 amps at a voltage of 240 volts.

Way more money in electricity than most people including myself would be willing to pay.

Yeah 2200 is conservative, the hammerhead for example uses a 1/3HP motor but realistically runs closer to 1/2HP.

Even if power wasn't a concern finding a pump head approved for aquarium use, especially saltwater, will be extremely difficult and the cost involved will be far beyond what you would pay for a pump that was actually made for the job and uses a fraction of the power.

Reeflo also has a high pressure pump (tigershark):

Pumps up to 84' using a max of 1065W.

You may also be able to find a panworld pump that can go up that high but your options are limited when it comes to pumping over 25'.

I have been looking at purpose built pumps, just figured I would weigh out my options. The reeflo has a pretty steep slope after 50'. Im thinking it will make more sense to just make a man closet in the other end of the basement. It will be much less hassle than running 40' of lateral pipe on top of the vertical parts too.
