How Does A Hydraulic Ram Pump Work?

Hydraulic ram pump may sound daunting, too technical, and scientific, but it is quite simple.

The simplicity behind the actual ram pump makes it ideal for communities and even for homes and farms. The principle behind the pump makes it reliable, affordable, and easy to maintain.

For a better understanding of how it works, certain words need to be described; 

Gravity – is a force that leads the body of water to the river

Kinetic energy – the energy an object has or produces for motion or movement.

Water hammer effect – or hydraulic shock. This is the effect of the sudden release of pressure on a gauge float.

How does it work?

First, remember that for the ram pump to work, the pump itself must be installed at the deepest part of the water source (for rivers and springs) or a lower elevation than the source of the flowing water. Then, water will enter the pump, pressure builds up and pushes him out into the higher elevations. Here is a simple way of how the whole cycle of work.

Collecting water – Pump must be positioned lower than the water source to catch the water through the pipe drive. Water is drawn into the pump by gravity; this is why there is a need for electricity or diesel.

Creating pressure – Water flowing move down through the drive pipe has kinetic energy. This energy will build up pressure in the pipeline.

Build more pressure – pressure on the pipeline will create a water hammer effects build the pressure. The pump will work by using all available pressure to deliver water up the pipe. 

Delivering water – At this point, the water in the delivery pipe can reach “a great distance or altitude is even higher than the original water source.”

These steps occur about 100 times per minute. To help you visualize, here is a video link, “How Ram Pump Works.”

How to build up the pressure in the pump?

Let’s dissect the parts of the pump is simplified to see how each piece works to create the required pressure.

Drive pipe- this is where the water from the source entry. It is usually buried to prevent damage by people or pets. It is essential to trip the pump not to have any corners. Bends will compromise the efficiency and durability of the pump.

Excess water valve – This section controls the amount of water the pump can deliver. If the valve is open too long or closing too quickly, then there will be less water delivered. Be sure to hire only the best Ram Pump installer, such as those of the Gilman Ram Pump and Enterprises, brand valves appropriately installed or break the efficiency of the pump.

Delivery pipe- this is where the water flows from the pump to the water consumers.

Impulse valve -Do not let its small size fool you; this part of the pump has a lot to do in the entire pumping cycle. Impulse valve left open and was forced to shut down the water pressure — this action of the valve impulse causing a shock wave at the pump. The shock wave propels the water delivery pipes. The impulse valve opens again after the pressure subsides. As a general rule, the heavier boost valve stroke creates slower, and more water is pumped.

Delivery valve- serves as a gateway between the pump and the pressure vessel or directly to the delivery pipe (depending on how the pump is made). A delivery valve can be anything from “a ball, swinging, diaphragm, or lift-check.” This valve opens to the pressure vessel or the delivery pipe as soon as there is enough pressure in the pump to push it open. Just close the back as soon as pressure subsides.

Vessel- pressure water is pushed through the valve into the delivery here. Air met with the air inside the vessel, causing it to compress and create the effect of water hammer.


The number of water consumers will get at the end of the delivery pipe is dependent on “rations delivery head to head supply.” Suppliers such as may be able to give the client an estimate of the expected volume is based on their calculations, after consultation.

On the other hand, the ram pumps energy efficiency of about 60% to 80%.

A ram pump is the best choice?

Ram pumps are energy efficient and sustainable. Operates continuously and can serve the public or your family for a few generations, depending on materials used or the installer’s skills. It is very reliable and easy to maintain, as well.

However, not all locations have the necessary water resources. There is also the issue of sedimentation, and a large amount of water is wasted.

Fortunately, many people from all over the world look for ways to solve some of the issues about the ram pump. There is a growing looking into making automatic control valves to accommodate different types of water sources and “enable maximum utilization of the water supply.”

Again, the simplicity principle ram pump makes it a device that can be easily redesigned to answer to the needs of today’s modern world while at the same time keeping things back to basics and more sustainable.
