    A serious water mover!
  

*by 4***N on Reviewed in the United States on 26 April 2018*

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!!

    Small modification makes this pump fire up EVERY time.
  

*by D***Y on Reviewed in the United States on 27 February 2017*

I am using this pump in a catch basin (not in a boat). Initially I found that it would run, but not pump on some (seemingly) random basis. (Others have reported the same experience). After testing several theories as to why, I finally landed on the problem and (simple) solution. Turns out that all centrifugal pumps (like this one) are 'non self priming'... period. What happens is... when the surrounding area the pump is located in (the catch basin in my case) dries out, then fills with water, air is trapped in the volute (the casing that surrounds the impeller). Then when the water rises and float switch closes and fires up the pump,  a form of cavitation occurs and the pump runs forever without pumping water, despite being surrounded with the stuff because all its pumping is air, which is not what it is designed to pump. As the dry sump fills with water it cannot enter the volute because the air in the volute has nowhere to go. My solution? I used a short length of 1/4" drip irrigation tubing and one of those barbed fitting. I cut off the barbed part on one end, drilled the outlet port on the pump #22 and pressed the fitting into the the top of the port and attached the tubing (see photos). Now when the dry catch basin fills with water the air in the volute can escape through that tube and by the time the catch basis fills with enough water to trip the float switch all the air in the volute has been expelled through the added tube and the pump works every time. Of course there is a small amount of water that is recirculated but given the capacity of this pump, its probably not even measurable.

*by R***Y on Reviewed in the United States on 7 August 2015*

The first one I purchased died during second use, overheated blistering the top and frying wiring. This is the replacement and it is getting babied in the hopes it will last. Only pumping filtered water, flushed with tap water after every use, and monitored constantly during use. This is not a pump I would use in a boat. It cannot handle the debris found in any bilge. My guess is grass shut down the first one. It is used to supply water to a sluice and the only debris available was bits of grass found in the paydirt.
