    do ye think you could put an extension on the bottom of a pump agitator to complete empty a tank as in the last two or three feet.i think it would have to be above impelor starting off but would it keep sucking if there was a 2 ft *9" pipe on it to bring to the bottom

    I don't think it would work, the impeller is designed to push rather than pull. It would be easier to use a vac tank for the last few feet;)

    If the seat's wet, sit on yer hat, a cool head is better than a wet ar5e.

    An agitator works on displacement so it pumps the slurry away from the impellor at pressure that then creates negative pressure on the underside of the impellor and that pressure needs to be filled thus sucking in more slurry. What you want to do in theory would be possible however before you start pumping the slurry the slurry level would have to be above the level of the impellor so as to force the air in the extension under the impellor out and fill the impellor with slurry (IE prime the pump). In other words If there is air between the top of the slurry and the bottom of the impellor even if its in the extension the impellor wont draw in the slurry. But if you could start pumping once the pump get liquid through it it will stay pumping. But if you stop pumping the impellor will empty and you wont be able to start again. Does this make any sense. Air is the enemy. Also the extension and even the bottom plate under the impellor need to be air tight so when the slurry goes below the level of the impellor that the air have no way in.

    Well said, agree with you 100%

    PS you're not an engineer by any chance?:o

    thanks i was thinking along similar lines .i was thinking of making a new plate for the bottom with the extension welded on.do a bit of moving slurry between tanks and it would be nice to empty a tank with out putting on the slurry tank-alot faster too
