The typical centrifugal pump will begin to exhibit a drop in the head‑capacity curve with as little as 1 percent (by volume) of free air in the pumpage, and will be limited in its minimum capacity to prevent the pump from becoming "air‑bound" (2). . A Horizontal Centrifugal Pump with an Inducer. This auxiliary impeller is called an .
Centrifugal pumps are widely used in various industries for fluid transportation and circulation. One crucial component of a centrifugal pump is the driver, which provides the necessary power to operate the pump efficiently. In this article, we will explore the role of the driver in a centrifugal pump system, including its operation, parts, pressure head, shaft, and common problems.
The Centrifugal pumpis working based on the centrifugal force and the name follows the same. Fluid enters into the pumps, gets the energy from the centrifugal force of the impeller, and raised its velocity and pressure. Due to this pressure, the liquid is transferred from one place to another. See more
Centrifugal Pump Operation
The driver on a centrifugal pump, typically a three-phase alternating-current induction motor, plays a vital role in converting electrical energy into mechanical energy to drive the pump impeller. When the motor is powered, it rotates the pump shaft, which in turn spins the impeller inside the pump casing. The rotating impeller creates a centrifugal force that pushes the fluid towards the pump outlet, generating the desired flow rate.
Centrifugal Pump Diagram
A typical centrifugal pump consists of several key components, including the pump casing, impeller, driver, shaft, and bearings. The driver, usually located at the top of the pump, is connected to the pump shaft via a coupling. The diagram below illustrates the basic layout of a centrifugal pump with the driver positioned above the pump casing.

Centrifugal Pump Parts
The driver on a centrifugal pump is composed of various parts that work together to ensure smooth pump operation. Some of the essential components of the driver include the motor housing, stator, rotor, bearings, cooling system, and electrical connections. Each part plays a crucial role in converting electrical energy into mechanical energy to drive the pump.
Centrifugal Pump Pressure Head
The pressure head generated by a centrifugal pump is directly influenced by the driver's power output. A more powerful driver can drive the pump impeller at higher speeds, resulting in increased pressure head and flow rate. It is essential to match the driver's horsepower to the pump's requirements to achieve optimal performance and efficiency.
Centrifugal Pump Shaft
The pump shaft is a critical component that connects the driver to the pump impeller. It transmits the rotational motion from the driver to the impeller, allowing the pump to transfer energy to the fluid. The shaft must be properly aligned and supported by bearings to prevent vibration and ensure smooth operation of the pump.
Vertical Centrifugal Pump
In some applications, vertical centrifugal pumps are used where space is limited or where the pump needs to lift fluid from a lower level. The driver on a vertical centrifugal pump is typically positioned at the top of the pump, driving the impeller through a vertical shaft. This configuration allows for efficient fluid transfer in vertical pipelines.
Centrifugal Pump Problems
Despite their reliability, centrifugal pumps can experience various issues related to the driver. Common problems include motor overheating, bearing failure, shaft misalignment, and electrical faults. Regular maintenance and monitoring of the driver are essential to prevent these issues and ensure the pump's continuous operation.
Centrifugal Pump Capacity
The main parts of the Centrifugal Pump are: 1. Impeller 2. Casing 3. Backplate 4. Suction & Discharge Nozzles 5. Suction pipe 6. A foot valve 7. Strainer 8. Suction nozzle or suction
In my experience, most centers use roller pumps for routine CPB, centrifugal for long term ECMO and cases with long predicted CPB times (redos, DHCA) or patients refusing blood products. Some centers used so little centrifugal that they just completely stopped using them for surgery CPB and use them solely for ECMO.
