Pumps are used in various application and of various capacity.Pumps can give us energy savings if we maintain then , select the correct type of pumps.Below metioned tips can result in substatial energy savings in pumps
Schedule pumps to turn off whenever possible .Putting up level sensors , float valves or pressure switchs
Avoid recirculation through bypass lines
Minimize throttling
Assess pumping system suitability for current application. Many installed systems are oversized, providing an opportunity to:
Install a smaller impeller or trim the existing one
Remove stages
Downsize pump
Install a smaller and/or a more efficient pump motor
Replace worn impellers
Reduce pump speed or install appropriate speed control devices
Install a slower speed motor
Change sheave diameters
Consider variable frequency drives
Consider alternative pump configurations
Pony pumps
Multiple pumps in parallel
Improve O&M practices
Establish basic system maintenance checklists and schedules
Establish a predictive maintenance program
Improve piping configuration
Use larger pipe sizes
Eliminate unnecessary turns, valves, accessories
Optimize pump inlet and outlet piping
Use monobloc pumps instead of motor coupled pumps wherever possible .
