Introduction

Ram-type pumps, also known as hydraulic ram pumps, utilize the energy of a large amount of low-head water to lift a smaller amount of water to a significantly higher head. These pumps have been employed for their reliability and efficiency in rural and off-grid water supply systems.

Operation Principle of Ram-Type Pumps

The ram-type pump operates using a cyclic water hammer effect. When water flows through the drive pipe, it builds up momentum. This water is abruptly halted by a check valve, causing a pressure spike or water hammer that allows a portion of water to be pushed through another valve and into an air chamber. The air chamber compresses due to this action, creating a stable and continuous flow of water into the delivery pipe.

Key Components of a Ram-Type Pump

• Drive Pipe: Directs the source water to the pump and is crucial in building the necessary velocity.
• Waste Valve: Intermittently closes to generate water hammer.
• Delivery Valve: Allows water to flow into the air chamber.
• Air Chamber: Stores energy as compressed air, stabilizing the discharge.
• Delivery Pipe: Transports water from the pump to the destination.

Performance Analysis and Specifications

Performance of a ram-type pump is influenced by several factors, including:

• Drive Head: The vertical drop available from the supply source, usually ranging from 1 to 3 meters.
• Delivery Head: The height water is lifted, potentially reaching up to 10 times the drive head.
• Efficiency: Typically around 60-80%, depending on precise construction and installation conditions.

Numerical Example:

Assuming a drive head of 2 meters and a drive flow rate of 150 liters/minute, with a delivery head of 15 meters:

Water Delivered = (150 liters/min) x 0.7 (efficiency) x (2/15) = 14 liters/min
