Pneumatic Cream Liquid Plunger Pump

A ram pump, also known as a hydraulic ram, is a type of water pump that operates using the force of flowing water. It does not require external power sources like electricity or fuel. The ram pump utilizes the kinetic energy of a large water flow to pump a smaller portion of water to a higher elevation. The basic principle behind a ram pump involves a series of valves and a momentum exchange process.

When water flows into the pump, a valve called the "waste valve" opens, allowing a fast-moving stream of water to enter and build up momentum. As the water reaches its maximum velocity, the waste valve suddenly closes, causing a pressure surge.

This pressure surge forces another valve, known as the "delivery valve," to open, allowing water to be pumped to a higher elevation. The momentum of the incoming water creates a pressure differential that pushes a portion of the water upwards against gravity.

As the delivery valve closes, the process repeats, creating a cyclic pumping action. Ram pumps are often used in areas where a constant and reliable water supply is needed, such as agricultural irrigation or rural water systems.

They are relatively simple and durable devices that require minimal maintenance. However, their efficiency depends on factors such as flow rate, elevation difference, and pipe diameters.

It's important to note that the use of ram pumps may have practical limitations in certain situations, and other pumping methods might be more suitable depending on the specific requirements and conditions.
