A hydraulic ram is a simple but effective device that can be used to lift water from a lower elevation to a higher elevation without the need for electricity or fuel. It is a self-acting pump that utilizes the energy of flowing water to create a pressure surge that forces water uphill. Hydraulic rams have been used for centuries, and they are still a valuable tool for providing water in remote or off-grid locations.
A hydraulic ram consists of a drive pipe, a waste valve, a delivery pipe, and an air chamber (see Figure 1). Water flows through the drive pipe and causes the waste valve to open. This creates a pressure surge that forces water into the delivery pipe. The air chamber cushions the pressure surge and helps to maintain a steady flow of water.

The efficiency of a hydraulic ram is determined by a number of factors, including the flow rate of the water, the height of the lift, and the friction loss in the pipes. The typical efficiency of a hydraulic ram is between 50% and 80%.
Hydraulic rams are used in a variety of applications, including:
Hydraulic rams are particularly well-suited for use in locations where there is a reliable source of flowing water, such as a river, stream, or spring. They can also be used to lift water from wells, but the flow rate must be sufficient to operate the ram.
Hydraulic rams offer a number of advantages over other water lifting devices, including:
Hydraulic rams also have some disadvantages, including:
When selecting a hydraulic ram, it is important to consider the following factors:
It is also important to select a ram that is made from durable materials and that is backed by a warranty.
Installing a hydraulic ram is a relatively simple process, but it is important to follow the manufacturer's instructions carefully. The following steps provide a general overview of the installation process:
Hydraulic rams are relatively trouble-free devices, but they can occasionally experience problems. The following are some common troubleshooting tips:
Hydraulic rams are a simple, effective, and sustainable way to lift water. They are ideal for use in remote or off-grid locations, and they can provide a reliable source of water for many years.
