When pumping water at depth in our project, we sometimes degas the water. This air and sometimes water ends up inside of a small presure vessel. The volume of the pressure vessel is about 30 liters. It would be desirable to discharge the air and the water into the surrounding seawater. The submerged depth is about 400 meters. The pressure vessel would generally be at about 10 to 40 psi or so. This sump pump would have to be very small and would not have to pump much volume, but it would have to handle both water and essentially air. It would be pumping against an approximate 600 psi presure head. Once the air and water are discharged, in an ideal case, there would only be something approximating a vacuum or patial vacuum in the presure vessel. Any comments on the existance of such a pump would be appreciated.
