The old fashioned “pitcher pump” had a handle, rod with a bucket piston on the bottom, barrel, casing, and check valve. Each stroke down on the handle pulled the rod upward in the barrel, which drew water up past the check valve. When the rod was raise, the bucket piston’s “leathers” allowed more water above them by compressing slightly away from the barrel, and this water was pushed upward and out the spout. This setup will lift water from about 30 feet.
Other hand operated water pumps use a diaphragm to suck in and then discharge water, and can be more efficient than pitcher pumps. The principal of the diaphragm sucking in water is similar to the pitcher pump, in that it draws in water and then pushes it out in the opposite direction.
