What is a Hydraulic Ram?

Hydraulic ram, commonly referred to as a Hydram, are water pumps that work by harnessing the momentum of moving water. They're an ideal choice for homesteaders and off-grid lifestylers since they require no external power source to run.

In essence, a ram pumps the flow of water from its source uphill through one delivery pipe and then back down again. This cyclic process wastes some water each time the delivery valve closes abruptly.

Hydraulic rams are a type of single-acting hydraulic cylinder

Hydraulic rams are a type of single-acting hydraulic cylinder used in many industrial machinery and mobile equipment applications.

Construction vehicles like excavators and bulldozers often employ hydraulic press operators for pressing presses and injection molders.

The hydraulic ram works on the principle of a "water hammer." When water is suddenly stopped, its momentum changes, creating an intense surge of pressure that can propel fluid to greater heights.

Single-acting cylinders tend to be smaller and more compact than their double-acting counterparts, which makes them ideal for various reasons such as lower manufacturing, installation and repair costs.

They're less costly to purchase and require fewer seals than double-acting versions, though they could leak if particles get inside the hydraulic cylinder. This could cause an incremental loss in performance as well as damage to its hydraulic seals.

They are used to raise water

Hydraulic rams are devices that utilize hydropower to lift water. To operate, you close a valve and use the kinetic energy of flowing water to pump a tube.

This type of pump requires no external power source and can lift water to great heights without the assistance of an electric motor. The ram is commonly used to provide drinking water for livestock in rural areas where access to reliable sources may be difficult or impossible.

Hydraulic rams have been around for over 200 years. In 1772, John Whitehurst created the first manually-operated version of this device which was later improved upon by Joseph Montgolfier in 1796.1

They are a pump

Hydraulic rams act like pumps, transporting water from one level to another without the need for external energy sources. They rely on built-up pressure in the water that passes through them for lifting it up and can run for extended periods before needing recharge with new liquid.

In the pumping process, water flows down a pipe from its source to an impulse valve (or waste valve) of a hydram. Friction draws it up and forces it shut, creating negative pressure within the pump body.

This creates a "pressure spike" in the stand pipe and drops across the swing check valve (where water exits), creating an "airlock." After this event occurs, water returns to flowing through the pump - about once or twice every second.

They are a device

Hydraulic rams are devices that use water's force to lift products. They may also be employed to program a machine's movement.

The ram works by harnessing the pressure energy created by a shock wave that occurs when water in a pipe is abruptly stopped. This shock wave causes some of the water to rise to higher levels, creating kinetic energy.

A hydraulic ram's effect is controlled by a valve on its delivery pipe. This enables it to cycle automatically if its weight or spring pressure are adjusted correctly.

Manually starting the ram is also possible by pushing it down several times until it cycles continuously. However, this process may take some time depending on its length and diameter.
