Query
Submersible pump is being selected for a project, but in ECBC, only details pertaining to induction pumps are provided. What details to consider in case for submersible pumps to demonstrate compliance with ECBC?
Solution
ECBC compliance must be followed for overall motor assembly, Which is as following according to the Efficiency curve :
1. 3 HP - 2.2 kW - 4 Pole - to meet ECBC compliance motor efficiency must be 85 or above (from table 8.4)
2. 2 HP - 1.5 kW - 6 Pole - to meet ECBC compliance motor efficiency must be 82.2 or above (from table 8.5)
The type of pump i.e. submersible or any other is insignificant as long as ECBC mandates are met.
