I recently picked up 2 large jet-pumps and an aerator. I have no information on the pumps and was hoping someone could give me some answers...

How many GPH are they? they say 2.5hp on the otherside if that helps anyone.

I would like to use these on a 700 gallon set up. Are they enough?

My concept is that gravity will feed water through a valve near the top of the tank and drop it down to a filter, the water will leave the filter and fall into a 50g tank, and the pump will resubmit it into the main tank.
If a motor fails, the water line will only drop to the level of the inlet, and will settle in the 50g tank until the motors are corrected.
I will probably only use one motor and have the other integrated as a backup system of valves and switches.

My idea for regulating the power (since they are 230v fed) is to have their own power sources, with a 230v compatible dimmer controlling their speed. I am concerned if this is feasible as the wiring diagram indicates that there are only 2 available speed options...

The aerator runs off standard 120v, and a basic dimmer will not cause an issue. For the aerator, I will run a 1" piece of PVC along the back of the tank, and drill holes every so inches. I am going for a natural theme so I want to descise the mechanic somehow. Taking Ideas now... Probably going to just have the drilled PVC hidden under a higher pile of riverstones.

Can anyone help me?
 
The pumps were in a 600 gallon hot tub, also, if that helps.

This is the closest I could get to the label without over exposing it.

so by zooming in, this is the most I can make out of the image...

Dimmers I plan on using for the pumps...

This is a single Leviton #IPI10-2LW white Illumatech slide dimmer. It is Commercial Specification Grade with preset ON/OFF switch - for 220VAC 50Hz ONLY (do not buy these if you do not have 220VAC 50Hz power). Features include:
  • Single-pole and multi-location lighting control when used with a 3-way switch
  • Rated 1000W 220VAC 50Hz incandescent - this is ONLY for 220VAC 50Hz power
  • Fluid slide movement allows fine adjustment of light level with minimal effort
  • Captured, wrap-around slide bar stays in place and cannot fall off during use
  • Easy-to-use pushbutton ON/OFF preset switch
  • LED locator light provides load status and makes it easier to find the switch in the dark
  • Power failure recovery ensures retention of last setting before power interruption
  • Built-in radio/TV interference filter
  • Compatible with Leviton color change kits so switching to a new color is a snap
  • Wallplates sold separately
 
I think that may be a problem in "dimming" the electricity going to the motor. I do not believe it works that way. You would giving the motor a controlled "brownout". I may be wrong.

You may want to try simply adding a tee to the return with a shut off going back to the sump, that you can easily open up to reduce the flow into the tank with out taxing/burning out the motor. As a side note do not put a shut off on the return alone to reduce the flow, that will also stain the motor.
Let it run free, baby.

why do you believe choking the output would strain the motor....it will pump less and reduce power consumption........a centrifigal pump works the hardest wide open as it is moving the maxium amount of water and hence doing the max amount of work.

you should not choke other types of pumps to the best of my knowledge.

if you choke the input it will cause cavitation and ruin the pump.

wouldnt the motors running constantly at high speed cause a heating issue?


no AC motors are designed to work at a specific speed see motor lable

1800 rpm, 3450 rpm etc
