Heavy duty submersible slurry pump

This thing could run off of a 5.5 kVA generator and pumps 100 gpm up a 35' head. It seems like it could drive a sluice pretty good. Don't know if this would work or not but it claims to be clog proof, sea water ready, and damned efficient.
This thing is brand new but it looks like like ITT bought them out. Here's a brochere:

Re: Heavy duty submersible slurry pump
This pump requires a 3 phase 460V generator. Did you have a specific 5.5kVA generator in mind?

Re: Heavy duty submersible slurry pump
This type of pump would work better. It has more head lift, and more Gal. per minute, also it is 115 volts.

If you look at their line of pumps you can find a good deal on the type you need. I am not endorsing them just the price range on their products and the power needed to run the pumps.
They carry more pumps than just this one.

Nathren:
While the Gorman Rupp seems to have a higher gpm rating I don't think it would perform as well in Nome. For one thing the largest solid it can take is 1.2". The Robot Pump weighs in at a hefty 470 pounds and can take 2" solids. The 460v / 3-phase electrical system while a little harder to deal with for a generator is nonetheless much more efficient. 10 amps full load current means that #12 wire would be enough to carry starting currents. The GR pump is rated for sewage. I don't know if it is listed for seawater.

The robot pump is actually available for $2500 at this site:

I think that a good make offer price could get this thing cheaper. I'm going to try and find the lift/volume curves for this pump. I'd guess that it is going to do lots better than 100 gpm at 20 feet underwater.
