what is the centrifugal pump
Centrifugal pumps are the most common and straightforward hydraulic equipment used across various industrial applications. They efficiently transfer fluids, including water, oils, and solvents, through converting electrical energy into mechanical energy. Their versatility, reputation for reliability and ability to provide a smooth flow make them a preferred choice in many industries. Centrifugal pumps come in different sizes and configurations, including single-stage for low-pressure applications, two-stage for medium-head tasks, and multi-stage pumps for high-head operations, catering to a wide range of fluid transport needs.
How does a centrifugal pump work?
The centrifugal pumps come in many shapes and sizes and consist of a pump and a motor. The electrical motor allows us to convert electrical energy into mechanical energy; the mechanical energy is used to drive the pump and move the liquid. The pump pulls the liquid in through the inlet and pushes it out through the outlet.
TYPES OF CENTRIFUGAL PUMPS
Centrifugal pumps are categorized based on stage, suction type, split case, shaft orientation, and standard specifications.The classification of centrifugal pumps by stage depends on the device’s number of impellers.
- Single-stage: The single-stage centrifugal pump has just one impeller housed within its casing. This makes it ideal for low-pressure operations as it maintains a substantial flow rate.
- Two-stage: This centrifugal pump type has two impellers functioning together to pump liquids. This device is well-suited to medium head applications.
- Multi-stage: Multi-stage pumps have three or more impellers used to achieve optimal efficiency. This particular centrifugal pump is recommended for high-head applications.
Benefits of the centrifugal pump
Centrifugal pumps offer many benefits. These include:
Ease of maintenance: Centrifugal pumps have low routine maintenance requirements. They have fewer moving parts than other pumps, which means less maintenance, lower costs and reduced downtime.
Smooth flow: Often, with conventional fluid-flowing pumps, they can pulsate, which can cause vibrations in piping systems. This concern is not associated with centrifugal pumps, as they can effectively mitigate this problem.
Wide range of sizes: Unlike other pumps, it occupies much less floor space for the same capacity. If you’d prefer a centrifugal pump with a large capacity, all you need to do is amplify the impeller speed and adjust the inlet diameter and outlet diameter accordingly.
Application Versatility: Centrifugal pump configuration is not a one-size-fits-all deal for all applications. The pumps can be adjusted to meet varying industry needs depending on the project. At Tricel, we offer a diverse range of pumps suited for multiple uses and catering to various project requirements.
Factors to Consider When Choosing a centrifugal Pump
Range and Condition
Centrifugal pumps are most efficient and minimise energy consumption when they operate in close proximity to their Best Efficiency Point (BEP). Operating outside this range can result in diminished efficiency, heightened energy usage, and premature wear and tear on the pump.
When it comes to selecting the appropriate size for a centrifugal pump, the flow is a crucial factor to consider. There are various ways to measure the flow, such as m³ per hour, litres per second, or gallons per minute.
The suction height is the distance between the start of the suction tube and the centrifugal pump. If this height exceeds ten metres, it is advisable to either choose or consider using a submersible pump.
