Using the force of gravity. In essence, a disc stack separator is a settling tank whose base is wrapped around the center line of the bowl. Rapid rotation of separator bowl means that the effect of gravity is replaced by a controllable centrifugal force, or gravitational force known as G-force, that can have an effect up to 10,000 times greater than the force of gravity.Proven and high efficient disk stack technology of large pharma production separators. Now available as compact single-use skid.

DISCS STACK SEPARATORS. Centrifugal separators are intended for mechanical separation of solid-liquid or solid-liquid-liquid suspensions. Separators are widely used in olive oil, dairy products, food and beverage production, juice production, oil refining and oil recovery. . The light phase flows in the center through the light phase paring .
Centrifugal pumps are widely used in various industries worldwide for their efficiency and reliability in moving fluids. These pumps work on the principle of converting mechanical energy from a motor into kinetic energy in the fluid being pumped. Understanding the working principle of a centrifugal pump is essential for ensuring optimal performance and maintenance. Let's delve into the different types of centrifugal pumps and how they work.
It is one of the simple and exciting topics in fluid mechanics.What is the need for a pump? We require a pump to transmit water from a region of low pressure to a region of higher pressure. The centrifugal pump defines as a hydraulic machine that converts mechanical energy into hydraulic energyby means of
Types of Centrifugal Pumps
Centrifugal pumps are classified based on various factors such as the number of impellers, type of casing, orientation, and position. Understanding these classifications can help in selecting the right pump for a specific application.
# Based on the Number of Impellers
1. **Single Stage Impeller:** A centrifugal pump with a single impeller is known as a single-stage pump. These pumps are commonly used for applications where low to moderate flow rates are required.
2. **Multistage Impeller:** In contrast, multistage centrifugal pumps have multiple impellers stacked in series. These pumps are suitable for high-pressure applications where the fluid needs to be pumped over long distances or to higher elevations.
# Based on the Type of Casing
1. **Volute Casing:** Centrifugal pumps with a volute casing have a spiral-shaped casing that gradually expands in diameter to convert velocity energy into pressure energy efficiently.
2. **Diffuser Casing:** In pumps with a diffuser casing, the casing contains a series of vanes that help in converting kinetic energy into pressure energy more effectively.
# Based on Orientation and Position
1. **Horizontal Centrifugal Pump:** These pumps have a horizontal shaft orientation and are commonly used in industrial applications where space is limited.
2. **Vertical Centrifugal Pump:** Vertical pumps have a vertical shaft orientation and are often used in applications where the pump needs to be submerged in the fluid being pumped.
Working Principle of a Centrifugal Pump
A centrifugal pump consists of several key components, including an impeller, casing, shaft, bearings, and a motor. The working principle of a centrifugal pump can be explained in the following steps:
1. **Impeller Rotation:** When the motor drives the shaft, the impeller attached to the shaft rotates at high speeds within the casing.
2. **Centrifugal Force:** As the impeller rotates, it creates a centrifugal force that pushes the fluid towards the outer edges of the impeller blades.
3. **Fluid Inlet:** The fluid enters the pump through the suction inlet located at the center of the impeller.
4. **Acceleration:** The rotating impeller accelerates the fluid radially outward, increasing its kinetic energy.
5. **Conversion of Kinetic Energy to Pressure Energy:** As the fluid moves through the impeller and into the casing, the expanding volute or diffuser casing converts the kinetic energy of the fluid into pressure energy.
6. **Discharge:** The pressurized fluid is then discharged through the pump outlet to the desired location.
