Centrifugal pumps are one of the most common and reliable machines used in industries today. They are widely used in food, beverage, pharmaceutical, and chemical plants because of their simple design, steady flow, and ability to handle a wide range of liquids.
But even the most efficient pumps gradually lose their efficiency if not properly chosen, operated, or maintained. Poor performance can lead to higher energy bills, product losses, and unnecessary downtime.

Understanding Centrifugal Pump Working
Before we discuss enhancements, let's quickly learn how a centrifugal pump functions.
A centrifugal pump working mechanism is simple in nature: it employs a rotating impeller to drive liquid using centrifugal force. The liquid is drawn in through the suction side, is accelerated by the impeller, and is expelled through the discharge at increased pressure.
Fristam's Hygienic centrifugal pumps are precision-engineered with high-grade stainless steel to provide efficient, smooth, and hygienic pumping even in challenging environments.
Why Focus on Efficiency?
An efficient pump conserves energy, lasts longer before maintenance, and provides consistent product quality. Inefficient pumps consume power wastefully, degrade more quickly, and may become an issue in the process stream.
Here are some easy yet useful tips to enhance your centrifugal pump performance and efficiency.
1. Select the Proper Pump
Efficiency begins with the right pump selection for your application. A pump that is oversized wastes unnecessary energy, while one that is too small cannot supply the demand.
Fristam assists customers in selecting a pump based on flow rate, head, pressure, temperature, and viscosity. This results in the pump operating near its best efficiency point (BEP), where it produces optimum flow using the least amount of energy.
2. Operate Near the Best Efficiency Point (BEP)
Each pump has a specific point on its performance curve known as the BEP. Operating the pump away from this point results in increased energy consumption, vibration, and wear.
Fristam pumps can work well at variable flow rates. But the closer you keep it to BEP, the better the performance and the longer the life of your pump.
3. Regularly Maintain Your Pump
Regular centrifugal pump maintenance is necessary to maintain high efficiency. Minor problems such as worn-out impellers or seals, plugged passages, or loose bearings can lower efficiency.
Below are some basic checks to incorporate in your maintenance program:
- Check and clean impellers.
- Inspect for leaks where seals are located.
- Listen for strange noise or vibration.
- Look for signs of wear or corrosion.
Fristam pumps are easy to maintain with hygienic designs facilitating Clean-in-Place (CIP) , which makes cleaning and maintenance much easier.
4. Design the Piping System Well
Poor piping design can waste a lot of energy and hurt centrifugal pump performance. Undersized pipes, tight curves, and long runs add resistance and compel the pump to labour more.
For improved efficiency:
- Keep the pipe as short and straight as possible.
- Use bigger diameter pipes where possible.
- Minimise unnecessary bends and valves.
- Ensure the suction line is adequate in size and not clogged.
5. Prevent Cavitation
Cavitation occurs when the pressure at the inlet of the pump falls below a level where it creates vapour bubbles that implode and damage the impeller. This not only lowers centrifugal pump efficiency but also shortens its lifespan.
To avoid cavitation:
- Ensure adequate liquid level in the suction tank.
- Keep the suction line short and smooth.
- Avoid running the pump at excessive speeds.
- High efficiency by design, saving energy and costs.
- Hygienic construction with stainless steel for food, beverage, and pharma applications.
- Smooth and quiet operation even at high speeds.
- Easy to clean and maintain, with CIP and SIP functionality.
- Durable components are made to last even in tough environments.
Fristam pumps are designed to limit cavitation risk when installed properly.
6. Consider Using a Variable Frequency Drive (VFD)
If your process requirements vary during the course of a day, a VFD can modulate the pump speed to meet flow demands. Energy consumption and mechanical stress are minimized.
Fristam pumps work seamlessly with VFDs, giving you more control over your operation and helping save on operating costs.
