minimum efficiency values for water pumps, with the target of reducing energy consumption. From now on, only pumps and motors which satisfy the energy efficiency requirements of the EU’s ErP Directive may be sold. MEI, the minimum efficiency index for standardized water pumps, was set up to be ≥ 0.4 since beginning of 2015.

Characteristics of a Centrifugal Pump
Centrifugal pumps are known for their simplicity, reliability, and high flow rates. They are capable of handling a wide range of liquids, from water to corrosive chemicals. Some key characteristics of centrifugal pumps include:
- Ability to generate high flow rates
- Relatively low maintenance requirements
- Suitable for a wide range of applications
- Efficiency in converting mechanical energy into hydraulic energy
Centrifugal Pump: How It Works
The basic principle behind the operation of a centrifugal pump is the conversion of mechanical energy from a motor or engine into kinetic energy in the liquid being pumped. The process can be summarized in the following steps:
1. The pump's impeller rotates, creating a centrifugal force that pushes the liquid towards the outer edges of the impeller.
2. As the liquid moves through the impeller, it gains kinetic energy and is thrown outwards into the pump volute.
3. The liquid exits the pump volute into the discharge piping, where it can be transported to its intended destination.
Types of Centrifugal Pump
There are several types of centrifugal pumps, each designed for specific applications and operating conditions. Some common types include:
- Single-stage centrifugal pump
- Multi-stage centrifugal pump
- Horizontal split-case centrifugal pump
- Vertical turbine centrifugal pump
- Submersible centrifugal pump
Each type has its unique features and advantages, making it suitable for different requirements in industries such as water treatment, oil and gas, and chemical processing.
Centrifugal Pump Parts and Function
A centrifugal pump consists of various components that work together to facilitate the pumping process. Some essential parts and their functions include:
- Impeller: Rotates to impart kinetic energy to the liquid.
- Volute Casing: Collects the liquid from the impeller and directs it towards the discharge piping.
- Shaft: Transfers rotational energy from the motor to the impeller.
- Bearings: Support the shaft and reduce friction during operation.
- Seal: Prevents leakage of liquid from the pump.
Understanding the role of each part is crucial for proper maintenance and troubleshooting of centrifugal pumps.
What Does Centrifugal Pump Mean?
A centrifugal pump is a mechanical device that uses centrifugal force to transfer liquids from one place to another. It is widely used in industries where the movement of liquids is required, such as water supply, irrigation, wastewater treatment, and chemical processing. The term "centrifugal" refers to the force generated by the rotation of the impeller, which propels the liquid through the pump.
Explain Working of Centrifugal Pump
The working of a centrifugal pump can be explained by the conversion of mechanical energy into kinetic energy in the liquid being pumped. As the impeller rotates, it creates a centrifugal force that pushes the liquid towards the outer edges of the impeller, imparting kinetic energy to the liquid. This kinetic energy is then utilized to move the liquid through the pump volute and into the discharge piping. The efficiency of a centrifugal pump depends on factors such as impeller design, pump speed, and operating conditions.
