where r u seeing the oil and water mixed??? the pump and gear reduction should both have seals to keep oil from leaking. if u see oil and water in the oil cup on the pump, you put the diaphrams in wrong or broke them doing it

diaphram pumps need water(spray solution) on 1 side of the diaphram and oil on the other side. running it dry on either one can damage the diaphrams
