It will do it easily although a little less than rated capacity. I pump 3 times as far and 5 times higher with a 5gpm pump on 1/2" line. The RV grade pumps commonly used for maple sap pumps are not waterproof but there are marine grade pumps that are available which are rated as waterproof. For example, Shurflo makes a model 4148 which is a waterproof version of their 4048 model. Cost is a little higher. I have ordered some different ones to test.
