Efficient Pumps and Motors

Pump efficiency may degrade 10 to 25% in its lifetime. Therefore, it can sometimes be more efficient to buy a new pump, also because newer models are more efficient. A number of pumps are available for specific pressure head and flow rate capacity requirements.Industry experts point out that this degrading performance is not necessarily due to the aging of the pump but can also be caused by changes in the process. Therefore, the decision for pump replacement requires thorough examination of different factors.

Similarly, a higher efficiency electric motor will deliver energy savings. Similar to the pumps, prior to making a decision to replace a motor, a number of factors need to be taken into consideration - including the size of the motor, and the demand dynamics.

Efficient Pumps and MotorsCosts & Benefits

Parent Process: Cross Cutting Technology
Energy Savings Potential

Replacing a pump with a new efficient one reduces the energy use by 2% to 10%.

Higher efficiency motors have been shown to increase the efficiency of the pump system by 2 to 5%.

CO2 Emission Reduction Potential
Costs

For a given duty, a pump that runs at the highest speed suitable for the application will generally be the most efficient option with the lowest initial cost.
