A newly granted patent (Publication Number: US11953018B2) discloses a pump assembly that includes a pump body, a motor shaft, and two pump stages with impellers connected to the motor shaft. The assembly also features a mixing chamber between the pump stages, isolated from the first stage, and a valve assembly for fluidic connections. The valve assembly can switch between different positions to control the flow of fluid through the pump assembly, allowing for various configurations of fluid inlet and outlet connections. The pump motor rotates the impellers at the same speed, providing efficient fluid acceleration and boosting capabilities.

Furthermore, the patent describes a method for switching fluid flow through the pump assembly by rotating the motor shaft and adjusting the valve assembly. The method involves connecting different fluid inlets to the pump stages, mixing fluids in the chamber, and directing the mixed fluid to different outlets based on the position of the valve assembly. By moving the valve assembly into different switched positions, the method enables precise control over the flow of fluids through the pump assembly, ensuring efficient pumping and mixing processes. Overall, the patented pump assembly and method offer a versatile and effective solution for managing fluid flow in various applications.
