The development of the rotary jet pump has a rich and evolving history, with its working principle, structure, characteristics, and applications continuously improving over time. The concept of the rotary jet pump can be traced back to 1923 when F. W. Krogh introduced the idea of applying the Pitot tube principle to pump design, which led to the creation of what was then called a "Pitot pump." The initial version of this pump was open and had several limitations, such as poor efficiency and limited pressure capabilities.
By the 1920s, engineers began developing a closed version of the Pitot pump, which improved performance and reliability. During World War II, both Germany and Britain started researching rotary jet pumps for use in rocket and missile technology. However, after the war, interest in rotary jet pump research declined significantly.
It wasn't until the 1960s that significant progress was made with the invention of the enclosed runner and cover, which allowed for the formation of a radial rotating impeller. This innovation marked the beginning of more advanced rotary jet pump designs and eventually led to the modern Pitot-tube-based jet pump model we know today.
As industries grew more demanding, there was an increasing need for high-pressure pumps that could operate efficiently across a wide range of flow rates and lift curves. These requirements were particularly evident in the food industry, where cleaning systems needed reliable, high-pressure pumps for applications such as meat packaging, brewing, fruit and vegetable canning, and beverage processing. Rotary jet pumps proved to be an ideal solution due to their ability to deliver consistent performance under varying conditions.
Beyond the food industry, similar needs existed in sectors like paper production, petrochemical refining, and power generation. In response to these demands, the first patented rotary jet pump was developed in the United States during the 1960s. By the 1970s, Kobe Corporation launched the first commercially available rotary jet pump, marking the start of its widespread adoption in industrial settings.
Throughout the 1970s and 1980s, there was a global surge in patenting activities related to rotary jet pumps, reflecting growing interest and technological advancements. Today, rotary jet pumps are widely recognized for their efficiency, durability, and adaptability, making them a key component in various industrial applications around the world.
