I'm using this in a recirculating water setup with a homemade shaker table setup. It is suspended high in a 55 gallon plastic garbage can with a divider and holy cow this is a serious water mover. 1.5" layflat hosing snugly slips over the outlet's beaded rim perfectly.I also have a 12 volt speed control hooked up to it and this Seaflo pump responds beautifully to any variable speed, which is necessary for the different flow rates needed to the shaker table's 1" spray bar 5/16" holes. It is exactly what I needed for having lots of adjustable headroom volume. it's a key function on my table for controlling the flour gold separation.This pump also delivers enough volume EASILY to run a rocker box sluice which I also use it for now,after seeing what this pump can do.it's hooked up there with an intermittent on off switch I work with my foot instead of dumping buckets of water down the rocker.The pump delivers a huge wash just by itself better than dealing with dumping buckets any day!I have two T 1.5" outlets drowning the 1/2" screen grizzly. All I do now is step on the switchand grab the rocker handle to shake a couple big shovelfuls.When I first got this pump I tested it with a 12foot 1.5" layflat connected to it, it filled the hose up quick!I pinched the end of the layflat closed half way and it easily shot that water stream 12' plus.Its an awesome powerful and SUPER QUIET pump.I already have on the work table the ultimate little bedrock crack cleaner utilizing classification in a bucketthat puts that stupid little Snare sluice gimmick to shame.It is successfully running my custom 3/4" to 1.5" Venturi I made out of clear vinyl hosingwith extreme suction.This 12volt 3700gph Seaflo pump surely delivers!!
