Pumping systems are used extensively in industry to provide cooling and lubrication services, to transfer fluids for processing, and to provide the motive force in hydraulic systems. In fact, many manufacturing plants rely on pumping systems for their daily operations. In the manufacturing sector, pumps represent 27% of the electricity used by industrial systems[1]. Pumps are also used extensively for water and wastewater transfer and treatment.
Energy-efficient operation of industrial pumping systems requires a system-level approach that takes into account both the supply and demand sides of the system and how each of the components interacts in relation to shifting demand patterns and operating conditions.
Top Ten Energy Efficiency Measures for Pumping Systems
- Shut down pumps when not needed by manufacturing processes
- Operate the minimum number of pumps that systems require
- Use variable speed control instead of throttle valves for flow control
- Trim or change pump impellers on oversized pumps
- Reduce pipe and valve pressure loss
- Re-optimize pumping system when system requirements change
- Restore internal clearances
- Replace worn throat bushings, wear rings, impellers, pump bowls
- When purchasing new pumps ensure that they are of proper sized/selection
- When fully worn, replace standard efficiency motors serving pumps with NEMA premium
