The advantages of a centrifugal pump over positive displacement pumps are as follows
- Efficiency: Centrifugal pumps are generally more efficient than positive displacement pumps, especially at higher flow rates.
- Maintenance: Centrifugal pumps typically require less maintenance than positive displacement pumps.
- Wear and tear: Positive displacement pumps are more prone to wear and tear as the mechanical parts are in contact with the fluid, while centrifugal pumps have less wear and tear.
- Size and cost: Centrifugal pumps are typically smaller and less expensive than positive displacement pumps.
- Flow rate: Centrifugal pumps have a variable flow rate, which can change with the pressure and head of the system, while positive displacement pumps have a fixed flow rate.
- Vibration and noise: Positive displacement pumps tend to have more vibration and noise than centrifugal pumps.
- Suction lift: Centrifugal pumps typically have a higher suction lift than positive displacement pumps, which means they can lift fluid higher.
- Handling of low-viscosity fluids: Centrifugal pumps are more suitable for handling low-viscosity fluids.
- Handling of large particles: Centrifugal pumps have less chances to get clogged with larger particles compared to positive displacement pumps.
- Handling of fluctuating flow rates: Centrifugal pumps can handle fluctuating flow rates more effectively than positive displacement pumps.
