Well Water Pumps - Force & Lifting Pumps

Pumps. Picture 44 shows a section of an ordinary lifting pump, in which, as the piston P is raised, the valve V is opened and water is drawn up into the cylinder, and at the next stroke it is drawn through the valve W and is thus conducted to the delivery pipe D. Picture 45 is a section through a force pump, in which the plunger is solid, and the water after being raised in the cylinder is forced up the delivery pipe D. Picture 46 is a force pump with a plunger in lieu of a piston, and is generally preferred because the packing is easily renewed.
