Liquid Jet Ejectors , also known as jet pumps or eductors, are devices used to pump, mix, and transport liquids, gases, and solids. They work based on the principle of fluid dynamics, where a high-velocity fluid is used to entrain and transport a lower-velocity fluid. The high-velocity fluid is usually referred to as the motive fluid, while the lower-velocity fluid is known as the suction fluid or the entrained fluid. Liquid Jet Ejectors are commonly used in various industries, including chemical, pharmaceutical, petrochemical, food and beverage, and wastewater treatment, among others. In this article, we will discuss the working principle of liquid jet ejectors, their applications, advantages, and disadvantages. Working Principle Liquid Jet Ejectors operate on the Bernoulli principle, which states that an increase in the velocity of a fluid results in a decrease in its pressure. The motive fluid is supplied at high pressure and velocity through a nozzle, creating a low-pressure zo
