6. A typical hydraulic ram pump system. Water from the source flows through the drive pipe (A) into the ram pump at (B). The ram pump functions as described above and forces some of the water up the delivery pipe (C) to the destination at (D). (L) is the length of the drive pipe, (F) is the head or vertical fall from the water source to the ram pump, while (E) is the vertical distance the water must be lifted.
