Here are its main roles: Suction of Fluid: The eye of the impeller acts as an entrance point for fluid into the impeller. It is located at the center of the impeller and connects … Suction Cavitation. Occurs when a pump is under low pressure or high vacuum conditions. Signs of suction cavitation will be around the eye of the impeller that will have .

Centrifugal pumps are most effective with low-viscosity fluids. When dealing with higher viscosity fluids, pump performance decreases significantly, requiring adjustments to the design or a different pump type altogether. 3. Suction Lift Limitations. Most centrifugal pumps have limited suction lift capabilities.
Eye of the Impeller Function

The impeller eye is a crucial component of a centrifugal pump, playing a key role in the pump's overall performance and efficiency. In single end suction pump types, the impeller eye serves as the entry point for the liquid being pumped. It is where the fluid is introduced to the impeller, which then imparts kinetic energy to the liquid, increasing its velocity and pressure as it moves through the pump.
One of the primary functions of the impeller eye is to ensure a balanced and uniform flow of liquid to the impeller blades. When the flow entering the impeller eye is not evenly distributed, it can lead to unbalanced thrust forces within the pump. This imbalance can result in increased bearing loads, reduced pump efficiency, and potential premature wear and failure of pump components.
Eye of the Impeller Diagram
A typical centrifugal pump impeller consists of several components, including the eye, blades, and hub. The impeller eye is located at the center of the impeller and is designed to facilitate the smooth entry of liquid into the impeller. Below is a diagram illustrating the key components of a centrifugal pump impeller, with a focus on the impeller eye:
Centrifugal Pumping Diagram
To better understand the operation of a centrifugal pump, it is essential to examine a centrifugal pumping diagram. This diagram provides a visual representation of how a centrifugal pump works, from the intake of fluid through the impeller eye to the discharge of pressurized fluid. Below is a simplified centrifugal pumping diagram highlighting the flow path of liquid through a centrifugal pump:
Centrifugal Pump Formula
In the design and operation of centrifugal pumps, various formulas are used to calculate key parameters such as pump head, flow rate, and efficiency. One of the fundamental formulas related to centrifugal pumps is the pump affinity laws, which describe the relationship between pump speed, flow rate, head, and power consumption. The formula for the pump affinity laws is as follows:
\[ Q2/Q1 = (N2/N1) \]
\[ H2/H1 = (N2/N1)^2 \]
\[ P2/P1 = (N2/N1)^3 \]
Where:
- \( Q \) = Flow rate
- \( H \) = Pump head
- \( P \) = Power consumption
- \( N \) = Pump speed
