vesivesipumpun

Vesivesipumpun is a Finnish term that translates to "water pump" or "water-jet pump". It refers to a type of pump that utilizes a high-speed jet of water to move or lift a fluid, often a lower-pressure liquid or a gas. The principle behind its operation is similar to that of an ejector or injector. A primary fluid, typically water, is accelerated through a nozzle, creating a region of low pressure. This low-pressure area then draws in the secondary fluid, which is then entrained by the high-speed primary jet and propelled forward.

Vesivesipumpun can be constructed from various materials, depending on the application and the fluids being handled. They are known for their simplicity, lack of moving parts (apart from the fluid flow itself), and reliability. This makes them suitable for use in environments where traditional mechanical pumps might fail or require excessive maintenance. Their efficiency can vary depending on the specific design and operating conditions, but they are often employed when a simple and robust solution is needed for fluid transfer. Applications can range from industrial processes to laboratory equipment, and even in some domestic water systems for specific purposes. The term emphasizes the use of water as the driving force for pumping.
