How the High Lifter Water Pump Works


Low pressure water from your water source enters the High Lifter and pushes against the Low Pressure Piston. As the Low Pressure Piston moves, water is squeezed against the High Pressure Piston. As the water is squeezed, pressure builds up in the High Pressure Cylinder. It is the difference in size between the large, Low Pressure Piston, and small High Pressure Piston which multiplies the pressure according to the principle of the Hydraulic Lever, discovered by Pascal in 1646. The pressurized water enters the Central Tube, goes through a check valve, and exits the High Lifter. It then flows up a pipe to your tank. The tank can be as high as 1000 feet above your water source.

The High Lifter Water Pump is the centerpiece of a gravity water pump system. It is a water pump that uses no power. The energy comes your spring, creek, or pond, which must be located above the pump. It has many advantages over a ram pump. It is quiet and automatically restarts itself if there is an interruption in the water source. It can operate on very low flows and can pump over 1000 feet Total Lift. Also it doesn’t need a big, heavy, steel drive pipe. Ordinary 3/4” black poly pipe will work fine in most instances. It is designed for residential and agricultural use. The output depends on a combination of Fall and Net Lift, The average is 200 to 740 gallons per day for the for the 9:1 model, and 400 to 1500 gallons per day for the 4.5:1 model. See the Output Chart for details.
