Pump

[dj_pnevans]

I am looking for a pump that is light, has a suction of 10mtr's, can be air or power driven, not to big. Can any one help me out with ideas. It will only be use for sea water and not used to much but must work when needed.

If I understand your abbreviation correctly, you want to be able to lift sea water about 10 meters.

The problem is that a perfect vacuum will lift distilled water about 10.6 meters. Sea water, with dissolved salt is heavier and therefore the maximum height would be less. It's just a simple physics problem.

[.RC.]

i thought the maximum lift was about 27 feet???

Utterly impossible. Better to use a submersible or sump pump at the bottom of the container. An air or water-driven venturi can work from above, but efficiency is terrible, assuming you have a place to discharge the voluminous outflow. This applies to any pumping system, BTW.

Cheers,
