Seeking ultimate pump efficiency
3 Feb 2014
Every plant owner wants their pumps to be energy efficient, but there is sometimes a trade-off to be made to ensure greater operational reliability.
Operating reliability and greater energy efficiency would appear to be the prime concerns of many pump users.
The two concerns are not wholly incompatible, for greater reliability means less downtime and fewer spare parts, while more efficient motors contribute to reduced energy costs.
Once pumps are installed and commissioned, it is expected that other than for regular activities such as greasing, cleaning etc, they should not need to be touched again until planned maintenance comes around.
Sacrificing some degree of energy efficiency if there are fewer breakdowns is typically acceptable. Simply attaching the latest energy efficient motor will not necessarily reduce energy costs significantly.
