The drawing shows a Lifter connected to a piston water pump. Using a Lifter to collect and store energy is what a Lifter does best and here the weight carried by the Carriage is raised to a sufficient height that, when released, can drive the pump.
The weight of the water in the pipe is a product of the pipe diameter and depth. A 4 inch pipe reaching a water source 500 feet below ground would contain water weighing about 2700 pounds. This is way too heavy to be lifted manually. However, with a Lifter the power needed can incrementally be applied in small tilting actions. A Lifter configured with one of several different tilting mechanisms can tilt up a 2700 lb Carriage and when allowed to drop from a specified height, bring up an equivalent amount of water based on the height of the Lifter. If a Lifter of this size were 33 feet high then each drop cycle would bring up:
( 33 / 500 ) x 2700 lbs = 178 lbs of water or 21 gallons
One may vary the weight in the Carriage, Lifter height and the Power Transfer Assembly to achieve a desired water delivery output based upon the depth of the well and the size of the pipe.
Lifter Used to Pump Deep Static Water
Other types of reciprocating pumps might also be used. Water moving systems such as paddle-wheels, screws, water ladders, etc. might all benefit by making a Lifter its prime mover.
The World Health Organization has a PDF describing several pumps that might be mechanized with a Lifter. Water-lifting devices
