Centrifugal pumps are designed to operate at one system condition like fixed speed, flow rate, head and fluid properties. But in actual scenarios pump operation may change or operate at different points and conditions like head and flow rate so performance may also be changed accordingly.Creating a resistance to the flow controls the kinetic energy of a liquid coming out of an impeller. The first resistance is created by the pump volute (casing), which catches the liquid and slows it down. When the liquid slows down in the pump casing, some of the kinetic energy is converted to pressure energy. It is the . See more

It is the maximum pressure a pump can produce. It is the pressure at the left side of the performance curve equivalent to a near zero flow rate. This metric is important for .
On August 2, 2022, a study was conducted to investigate the mechanism of the rotor-stator interaction in a centrifugal pump. This research delved into the intricate workings of the centrifugal pump stator, a crucial component in the operation of these pumps. In this article, we will explore the significance of the pump stator, its design, and its role in various types of pumps such as screw pumps, mono positive displacement pumps, and progressive cavity pumps.
In this paper, the mechanism of the rotor–stator interaction in a centrifugal pump
Pump Stator Definition
The pump stator is a stationary component in a centrifugal pump that works in conjunction with the rotating impeller to impart energy to the fluid being pumped. It is designed to guide and direct the flow of the fluid through the pump, converting mechanical energy from the motor into kinetic energy in the fluid. The stator is typically made of materials that can withstand the abrasive and corrosive nature of the fluids being pumped.
Stator Pump Diagram
A stator pump diagram illustrates the components of the pump stator and how it interacts with the impeller. The diagram shows the stationary housing of the stator, which contains the volute or diffuser that helps to convert velocity energy into pressure energy. The diagram also highlights the clearance between the impeller and the stator, which is crucial for efficient pump operation.
Screw Pump Rotor and Stator
In screw pumps, the rotor and stator play a critical role in the pumping process. The rotor is a helical screw that rotates within the stator, creating chambers between the rotor and stator walls. As the rotor turns, these chambers progress along the length of the pump, trapping and moving the fluid from the suction side to the discharge side. The close tolerance between the rotor and stator ensures efficient pumping with minimal leakage.
Mono Positive Displacement Pump
Mono positive displacement pumps, also known as progressing cavity pumps, utilize a single helical rotor within a double helical stator to generate a progressive cavity. This design allows for the gentle handling of shear-sensitive fluids and the ability to pump viscous or abrasive materials with ease. The positive displacement action of the pump ensures a consistent flow rate regardless of changes in pressure or viscosity.
Starter for Submersible Pump
The starter for a submersible pump is an essential component that controls the electrical supply to the pump motor. It regulates the starting and stopping of the pump, protects the motor from overload conditions, and ensures smooth operation of the pump system. The starter may incorporate features such as thermal protection, phase loss detection, and motor soft-start functions to enhance the reliability and longevity of the submersible pump.
Progressive Pump Stator Diagram
A progressive pump stator diagram showcases the unique design of the stator in a progressive cavity pump. The diagram illustrates the helical shape of the stator, which complements the rotation of the rotor to create a series of sealed cavities that progress along the length of the pump. This progressive displacement action results in a steady flow of fluid with minimal pulsation and shear, making it ideal for handling sensitive or viscous fluids.
Stator Pump Parts
The stator pump parts include the stator housing, stator core, stator windings, and insulation materials. The stator housing provides a protective enclosure for the stator core and windings, ensuring proper alignment and support for the components. The stator core is typically made of laminated steel to minimize eddy current losses and improve magnetic efficiency. The stator windings are coils of wire that carry the electrical current to generate the magnetic field necessary for pump operation.
