What is chain pump?

A chain pump is a type of water pump that uses a continuous loop of chain to lift water from a lower to a higher elevation. The chain pump consists of a series of linked metal or plastic discs that are attached to a chain, which is driven by a crank or a motor.

Chain pumps have been used for centuries to lift water for irrigation, drainage, and other purposes. They are simple in design and can be easily constructed using basic materials. Chain pumps are commonly used in rural areas where access to electricity or other modern pumping technologies may be limited.

One of the key advantages of chain pumps is their ability to lift water over long distances and to higher elevations without requiring a large amount of power. However, chain pumps can be inefficient compared to other types of pumps, as they are limited in the amount of water they can lift and the height they can reach.

Overall, chain pumps are a cost-effective and reliable solution for lifting water in low-resource settings, and they continue to be used in many parts of the world today.
