Vacuum degassing worked fairly well and when combined with sonication, was effective for most applications. But degassing was always a bother and even with good lab habits, bubble problems were still number one .

Centrifugal pumps are widely used in various industries for transferring fluids from one place to another. They work on the principle of converting rotational kinetic energy into hydrodynamic energy to move the fluid. Understanding the main parts of a centrifugal pump is essential for its proper operation and maintenance. Centrifugal pumps can be classified into many types based on various factors such as the number of impellers or stages, impeller design, case-split orientation, type of volute, bearing support, shaft orientation, and other miscellaneous features.

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

Number of Impellers or Stages

The number of impellers or stages in a centrifugal pump determines its capacity to generate pressure and flow rate. Single-stage pumps have only one impeller and are suitable for low to moderate pressure applications. On the other hand, multi-stage pumps have multiple impellers arranged in series to achieve higher pressure levels. Each impeller in a multi-stage pump contributes to increasing the overall pressure of the fluid.

Impeller Design

The design of the impeller plays a crucial role in the performance of a centrifugal pump. Different impeller designs, such as closed, semi-open, and open, are used based on the application requirements. Closed impellers provide higher efficiency and are suitable for handling clean fluids, while open impellers are used for pumping liquids with solid particles.

Case-Split Orientation

The orientation of the case-split in a centrifugal pump can be horizontal or vertical. Horizontal split-case pumps have a horizontally split casing, making it easier to access and maintain the internal components. Vertical split-case pumps, on the other hand, have a vertically split casing and are commonly used in applications where space is limited.

Type of Volute

The volute is a crucial part of a centrifugal pump that converts the kinetic energy of the fluid into pressure. Different types of volutes, such as single volute and double volute, are used based on the pump's design and performance requirements. The volute helps in reducing the velocity of the fluid and directing it towards the discharge outlet.

Bearing Support

Bearing support is essential for the smooth operation of a centrifugal pump. Bearings help in supporting the rotating shaft and impeller assembly, reducing friction and ensuring proper alignment. The type of bearing support used in a pump can impact its reliability and maintenance requirements.

Shaft Orientation

The orientation of the shaft in a centrifugal pump can be horizontal or vertical. Horizontal shaft pumps are commonly used in industrial applications where the pump is mounted on a horizontal surface. Vertical shaft pumps are used in applications where space is limited, and the pump needs to be installed vertically.
