Declared overall Eff.

Min. overall Eff. for field condition

21-40 50 >57% >54.15%

41-100 75-97 >61% >57.95%

The above mentioned Overall Efficiency is minimum required for Field condition as per GEDA Norms.

IRMA Findings

Only 21% of EE pumps of average age of 1 yr and 35% of average age of 3 months met with GEDA efficiency norms

Increase in failure rate with age may be related to poor design efficiency of the pumps.

EE pumps are more energy efficient (combined median 49.82%) than non EE Pumps (combined median 40.87).
